Medical education is still worth the cost

 

In 2000, the soaring dot.com industry crashed. Seven years later, the housing boom ended abruptly. With tuition rates swelling, could the medical education market be the next bubble to burst?

Probably not, concludes a paper published Oct. 30 in the New England Journal of Medicine and co-authored by Cornell health economist Sean Nicholson, since such a collapse would occur only if doctors’ incomes dropped sharply and before medical schools could act to rein in costs. However, for veterinarians, optometrists, pharmacists, dentists and certain types of newly minted M.D.s, the prognosis is not so encouraging.

The article, “A Medical Education Bubble Market?,” is co-authored by David A. Asch, M.D. ’84, professor of medicine at the University of Pennsylvania, and Marko Vujicic of the American Dental Association.

A bubble market occurs when a good becomes overvalued because buyers are willing to pay higher prices in hopes of selling it for a greater payoff. The bubble deflates when the asset suddenly returns to a more reasonable intrinsic value, leaving buyers from the peak of the boom with something worth far less than what they paid.

In U.S. health care, medical education costs have risen sharply in recent decades, but medical school slots remain competitive in part because applicants believe their lucrative future wages justify taking on significant debt. But the economics have become much less favorable in the past 15 years, the authors found, based on debt-to-income ratio – the average debt of a graduating student compared to the average annual income of a newly employed physician in that field.

“Debt-to-income ratios reflect what students must borrow rather than what they must pay and, given whatever other assets they may have, how much into the hole they have to go,” the authors write. “Thus, these ratios may better reflect how students actually feel about buying education.”

Family physicians and psychiatrists are the worst off their first year out of school: In 2010, their debt equaled about 85 percent and 80 percent of their yearly income, respectively. That’s roughly double the ratio new doctors in those same fields faced in 1996. Doctors in specialized fields fared much better: Orthopedists, cardiologists and radiologists held a debt-to-income ratio under 35 percent – only a slight rise from 1996 levels.

But the picture is far more troubling for other doctors. The ratio for new veterinarians climbed above 160 percent in 2010, with optometrists (130 percent), pharmacists (110 percent) and dentists (95 percent) not far behind. In fact, veterinary medicine may already be in a bubble market, the authors argue.

As long as physician salaries remain high enough to justify their debt burden, medical education should avoid a similar fate. But, the authors warn, “there are strong signs that we can’t or won’t … keep paying doctors a lot of money.”

The Affordable Care Act is funded largely by reduced Medicare payments to hospitals, part of a growing demand to cut U.S. health care costs. Doctors’ incomes, though sluggish, have been spared so far but could be targeted soon as more savings are sought.

“The main point we are trying to make is the connection between what we as a society are spending on physician services and how much medical schools can charge for tuition,” said Nicholson, professor of policy analysis and management in the College of Human Ecology. “If we are serious about reducing health care spending, then that means we also need to cut the cost of creating new doctors if we want to continue to attract the most promising applicants into the profession.”

The study was funded, in part, by the American Dental Association.

At 107, nation’s oldest veteran enjoys limelight

Richard Overton, believed to be the oldest living United States veteran at 107, accepted a box of cigars and a standing ovation Thursday with a humble demeanor and a beaming smile.

More than 100 people packed a conference room at the Stephen F. Austin building in downtown Austin to attend a pre-Veterans Day ceremony in Austin honoring Overton and Ken Wallingford, who spent 10 months in a tiger cage as a prisoner of war in Vietnam.

“I’ve gotten so many letters and so many thank yous and I enjoy every bit of it, but I’m still going to enjoy some more,” said Overton, who is planning a visit with President Barack Obama next week in Washington, D.C.

Ex-state employee

Overton, identified by the General Land Office as the nation’s oldest veteran, was born in Bastrop County. He served in the Army during World War II in the South Pacific and now lives in Austin. He sold furniture in Austin after the war and later worked for the state Treasurer’s Office.

He drives and walks without a cane. During a television interview in March, he told a reporter that he doesn’t take medicine, smokes cigars every day and takes whiskey in his morning coffee. The key to living to his age, he said, is simply “staying out of trouble.”

The day’s ceremony, sponsored by the General Land Office, also recognized Wallingford, who shared his experience in captivity in the Cambodian jungle as the audience listened in amazement.

The former Army sniper, now 65, alternately laughed and became emotional as he told the story of his imprisonment and triumphant return home.

“As we look forward to Veterans Day I hope each and every one of us can remember those who have served, and importantly, those who serve today,” said Wallingford, who is veterans liaison for the Veterans Land Board.

Emotional memories

Wallingford brought a food and water bowl, sandals, pajamas and photos from his imprisonment in April 1972 to being set free in February 1973. His voiced cracked as he described his return to the United States.

“We weren’t going to leave without you guys,” Wallingford remembered hearing in the Army helicopter on his way out.

President Lyndon B. Johnson offered Wallingford and the other POWs who returned with him the presidential suite and staff of the Brooke Army Medical Center in San Antonio, he said.

Bill McLemore, deputy commissioner for the Veterans Land Board and a retired Army colonel, served with Wallingford. “Most veterans are just looking to have someone reaffirm that what they’ve done was an honorable thing to do,” McLemore said.

Kids of less-educated moms may have noisier brains

A mother’s level of education has strong implications for a child’s development. Northwestern University researchers show in a new study that low maternal education is linked to a noisier nervous system in children, which could affect their learning.

 “You really can think of it as static on your radio that then will get in the way of hearing the announcer’s voice,” says Nina Kraus, senior author of the study and researcher at the Auditory Neuroscience Laboratory at Northwestern University.

The study, published in the Journal of Neuroscience, is part of a larger initiative working with children in public high schools in inner-city Chicago. The adolescents are tracked from ninth to 12th grade. An additional group of children in the gang-reduction zones of Los Angeles are also being tracked.

Kraus and colleagues are more broadly looking at how music experience, through classroom group-based musical experience, could offset certain negative effects of poverty.  But first, they wanted to see what biological effects poverty may have on the adolescents’ brain. In this particular study, 66 children – a small sample – in Chicago participated.

Those whose mothers had a “lower education” tended to have not graduated from high school. Kraus’s study did not directly track income of families, but most children in the study qualified for free lunch (to be eligible, a family of four must have income of about $29,000 or less).

Researchers found “children from lower-SES (socioeconomic status) backgrounds are exposed to less complex and linguistically rich input in addition to hearing fewer words per hour from their caregivers,” according to the study.

The new study shows that in a group of adolescents from inner-city Chicago, the nervous system is different, depending on an individual’s mother’s level of education– both in the absence of stimulation, and when the brain is stimulated by sound. The same children who showed more “noise” in the nervous system performed worse on standardized tests of memory and reading. Researchers used scalp electrodes to measure the ongoing electrical activity in kids’ brains.

Among children of less-educated mothers, study authors found more noise in the absence of sound, compared to those with mothers who had more education.  Additionally, the nervous system’s response to sound was less strong and less precise among children of less-educated mothers.

“You have this double whammy, if you will, of having a poorer signal coming through, and heightened background neural activity,” Kraus said. “That’s a signal-to-noise disaster.”

Kraus and colleagues also found that when children of lower-educated mother hear the same sound repeatedly, nervous system responses tended to vary, whereas those of more highly-educated mothers responded the same way each time.

“If the nervous system responds inconsistently to the same sound, how is a kid to learn what the sound means, because he’s getting this jittered input?” Kraus said.

Researchers saw that the sound waves and brain waves physically resemble each other, so they could see what components of the sounds a child’s brain is processing, or not. “The implications are very important once, vis-a-vis education. It just reinforces the idea that education is important, not just for you but for your children,” Kraus said.

You might be asking yourself: Is nature or nurture to blame? “It’s difficult to know where the deprivation starts,” Kraus said. “The data here point to environmental causes.”

Although this study did not measure other lifestyle factors directly, low maternal education is associated with poorer nutrition, less availability of books in the home, less exercise and less encouragement of children do their homework, Kraus said. All of these deficiencies could play a role in the development of a child’s nervous system.

Previous research has also indicated that a mother’s education matters in terms of a child’s auditory development and auditory language enrichment, which is necessary for language skills to develop. A study by Betty Hart and Todd R. Risley found that by the time a child from a family on welfare is 3 years old, he or she will have heard 30 million fewer words than if the parents are professionals. By the fourth year, an average child in a professional family would have accumulated experience with almost 45 million words, compared to an average child in a welfare family (13 million words).

Welfare children tend to also hear far more discouraging language than those whose parents are professionals, the research showed. When young children aren’t being exposed to a wealth of words, and the language they do hear is more negative than what their peers hear, their development can be noticeably different.

The researchers are interested to see what effect music education has on these children and the others in their study. Their hypothesis is that music will help, especially with strengthening language skills.

“In the same way as getting linguistic stimulation is a form of enrichment, because you are making sound-to-meaning connections all the time, and you are strengthening circuits in the nervous system that are important for language, music also strengthens many of these same circuits,” Kraus said.

A second study released this week in JAMA Pediatrics shows poverty also affects the hippocampus and amygdala parts of children’s brains.

A baby’s gaze may signal autism, study finds

When and how long a baby looks at other people’s eyes offers the earliest behavioral sign to date that a child is likely to develop autism, scientists are reporting.

In a study published Wednesday, researchers using eye-tracking technology found that children who were found to have autism at age 3 looked less at people’s eyes when they were babies than children who did not develop autism.

But contrary to what the researchers expected, the difference was not apparent at birth. It emerged in the next few months, and autism experts said that might suggest a window during which the progression toward autism can be halted or slowed.

The study, published online in the journal Nature, found that infants who later developed autism began spending less time looking at people’s eyes between 2 and 6 months of age and paid less attention to eyes as they grew older. By contrast, babies who did not develop autism looked increasingly at people’s eyes until about 9 months old, and then kept their attention to eyes fairly constant into toddlerhood.

“This paper is a major leap forward,” said Dr. Lonnie Zwaigenbaum, a pediatrician and autism researcher at the University of Alberta who was not involved in the study. “Documenting that there’s a developmental difference between 2 and 6 months is a major, major finding.”

The authors, Warren R. Jones and Ami Klin, both of the Marcus Autism Center and Emory University, also found that babies who showed the steepest decline in looking at people’s eyes over time developed the most severe autism.

“Kids whose eye fixation falls off most rapidly are the ones who later on are the most socially disabled and show the most symptoms,” said Jones, director of research at the autism center.

“These are the earliest known signs of social disability, and they are associated with outcome and with symptom severity. Our ultimate goal is to translate this discovery into a tool for early identification” of children with autism.

The eye-tracking differences are not something parents and pediatricians would be able to perceive without the technology and expertise of an autism clinic, Jones said. “We don’t want to create concern in parents that if a child isn’t looking them in the eyes all the time, it’s a problem,” he said. “It’s not. Children are looking all over the place.”

Autism therapies have not yet been developed for young babies, but there are efforts to adapt intensive behavioral therapy for use with children as young as 12 months, Jones said.

Diagnoses of autism have increased, according to the Centers for Disease Control and Prevention, from one child in 150 in 2002 to one in 88 in 2008. The reasons are unclear, although some factors could be greater awareness of the disorder and a growing number of older fathers.

Jones and Klin, who directs the autism center, studied two groups of babies. One group was at high risk for autism, with a 20 times greater likelihood of developing it because they had siblings with the disorder. The other group was at low risk, with no relatives with autism.

The researchers assessed 110 children, from 2 months to 2 years of age, 10 times while watching videos of friendly women acting like playful caregivers. Eye-tracking technology traced when the babies looked at the women’s eyes, mouths and bodies, as well as toys or other objects in the background. At age 3, the children were evaluated for autism. Ultimately, researchers used data from 36 boys, 11 of whom developed autism. (They excluded data from girls, because only two developed autism.)

While the number of children studied was small – and the researchers are now studying more children – experts not involved in the study said the results were significant because of the careful and repeated measurements that were not just snapshots, but showed change over time.

“It’s well done and very important,” said Dr. Geraldine Dawson, director of the Center for Autism Diagnosis and Treatment at Duke University. She said it was notable that “early on these babies look quite normal; this really gives us a clue to brain development.”

She said a possible explanation was that, early in life, activities like looking at faces are essentially reflexes “controlled by lower cortical regions of the brain that are likely intact” in children with autism. But “as the brain develops, babies begin to use these behaviors in a more intentional way. They can look at what they want to look at. We think that these higher cortical regions are the ones that are not working the same” as in typical children.

The researchers found that children who developed autism paid somewhat more attention to mouths and sustained attention to bodies past the age when typical children became less interested. Even more noticeable was that children who developed autism looked more at objects after the first year, while typical children’s interest in objects declined.

“We’re measuring what babies see, but more importantly we’re measuring what they don’t see,” Jones said.

Cornmeal Coconut Biscotti

When I use grainy flour like cornmeal I always include some fat in the biscotti, and this time I went with coconut oil, which contributes great flavor and a sweet perfume. Use fine or medium-grind cornmeal and make sure to use fine coconut flakes. I used organic sugar (not brown) for these; the sugar is off-white rather than white, and coarser than regular granulated sugar.

  • 125 grams (approximately 1 cup) whole wheat flour
  • 30 grams (approximately 1/4 cup) all-purpose flour
  • 125 grams (approximately 3/4 cup) fine or medium-ground cornmeal
  • 90 grams (approximately 1 cup) unsweetened fine coconut flakes.
  • 5 grams (approximately 1 teaspoon) baking powder
  • Pinch of salt
  • 55 grams (2 ounces) coconut oil
  • 125 grams (2/3 cup tightly packed) organic sugar
  • 165 grams (3 large) eggs
  • 5 grams (approximately 1 teaspoon) vanilla extract

1. Preheat the oven to 300 degrees. Line a baking sheet with parchment. Whisk together the flours, cornmeal, coconut flakes, baking powder and salt in a bowl.

2. In the bowl of a stand mixer, or in a large bowl with a whisk or electric beater, beat together the coconut oil and sugar at medium speed for 2 minutes. Scrape down the sides of the bowl and the beater. Add the eggs and vanilla and beat together for another minute. Scrape down the sides of the bowl and the beater. Turn off the mixer and add the flour mixture. Mix in at low speed until combined. The batter will be moist and sticky.

3. using a spatula or a bowl scraper, scrape out half the batter onto the baking sheet. Moisten your hands so the dough won’t stick, and form a log, about 10 inches long by 2 1/2 inches wide. Repeat with the other half of the batter. The logs can be on the same baking sheet but make sure there is at least 2 inches of space between them.

4. Place in the oven and bake 40 to 45 minutes, until lightly browned, beginning to crack on the top, and dry. Remove from the oven and cool on a rack for 20 minutes (or longer). Place on a cutting board and cut 1/2 inch slices straight across the logs.

5. Place the cookies on baking sheets and return, one sheet at a time, to the middle rack of the oven. Bake 15 minutes and flip the biscotti over. Bake another 10 minutes, or until lightly browned. Remove from the heat and allow cooling.

Yield: 3 dozen biscotti

Advance preparation: You can bake the logs a day ahead and slice and double bake the cookies the next day. Biscotti keep for a couple of weeks in a tin or a jar.

Nutritional information per cookie (3 dozen): 76 calories; 4 grams fat; 3 grams saturated fat; 0 grams polyunsaturated fat; 0 grams monounsaturated fat; 16 milligrams cholesterol; 10 grams carbohydrates; 1 gram dietary fiber; 22 milligrams sodium; 2 grams protein

Dr Santosh Honavar wins Jerry A Shields International Award

Dr Santosh G Honavar, director of medical services, Centre for Sight Group of Eye Hospitals, has won the Jerry A Shields International Award for Excellence in Ocular Oncology. The award will be presented to him at the International Symposium of Ophthalmology at Guangzhou, China on November 10.

Dr Honavar currently heads the Centre of Excellence in Ophthalmic and Facial Plastic Surgery and Ocular Oncology at the Centre for Sight, Hyderabad and has established the National Retinoblastoma Foundation for the comprehensive, cost-effective, and evidence-based care of children with retinoblastoma with life, eye and vision salvage.

He is picked up for the award in recognition of his work on the management of advanced retinoblastoma with improved life, eye and vision salvage. His original clinical research has culminated in safe and cost-effective management protocols for advanced retinoblastoma that have resulted in over 95 per cent patient survival, 90 per cent eye salvage, and 85 per cent vision salvage, a paradigm change from the dismal 50 per cent mortality and 70 per cent chance for loss of an eye only a few years ago, according to a media release.

Retinoblastoma is the most common cancer of the eye in children. Its significance lies in the fact that in countries like India, it is often left undiagnosed, and hence untreated for too long, resulting in high mortality. Over 75 per cent of the children present with very advanced tumours in India, and 50 per cent of them would die, before Dr Honavar applied the existing treatment protocol, the release said.

Dr Honavar’s research has had significant impact on the diagnosis and management of retinoblastoma and its outcome. His major contributions encompass all aspects of diagnosis and management of retinoblastoma including recognition of atypical manifestations, high-dose chemoreduction to optimize visual potential, refinement of the enucleation technique, identification of histopathologic high-risk factors and adjuvant therapy to reduce the risk of metastasis, multimodal therapy for orbital retinoblastoma and identification of genetic mutations.

The work on retinoblastoma led to Dr Honavar being conferred the Shanti Swaroop Bhatnagar Award by the Government of India in 2009. But it has had other, more important consequences; it has led to the consolidation of a distinct subspecialty in eye care, ocular oncology, with students completing their training, and moving on to take this approach to care to other centres in India and elsewhere, the release added.

Officials ink deal to create medical school in Las Vegas

Nevada’s university leaders have signed a partnership agreement to begin establishing a new M.D.-granting medical school in Southern Nevada.

The agreement, or memorandum of understanding, outlines a vision for UNLV and the University of Nevada School of Medicine at UNR to work together to create a four-year medical school at UNLV that would mint medical doctors.

The UNLV medical school would open under the University of Nevada medical school’s accreditation, but will eventually become its own independently operated, separately accredited and financially-sustainable medical school.

Nevada System of Higher Education Chancellor Dan Klaich, UNR President Marc Johnson, University of Nevada School of Medicine Dean Tom Schwenk and UNLV President Neal Smatresk signed the agreement on Wednesday. Nevada regents are expected to vote on the agreement at their December board meeting.

“Increasing the medical education and health care options for Nevadans has always been a top priority for the Nevada System of Higher Education,” Klaich said in a statement. “I’m proud of the collaboration between our two universities and their efforts to bring these long-discussed plans from the drawing board to reality.”

Earlier this year, Nevada’s higher education leaders — led by Regent Mark Doubrava — directed UNLV and UNR to begin developing plans for a UNLV medical school while continuing to develop the medical school at UNR. UNLV’s faculty senate and graduate student government also supported plans for an on-campus medical school.

Currently, UNR operates the University of Nevada School of Medicine; students complete their core classes in Reno and can complete their clinical training in Reno and at University Medical Center in Las Vegas.

Proponents of a UNLV medical school have long argued that the current model for medical education in Nevada has not served Southern Nevada, by solving its shortage of physicians. Las Vegas is the largest metropolitan area in the United States without an allopathic medical school.

Over the years, Nevada’s higher education leaders have proposed different ways to expand the current medical school’s footprint in Southern Nevada by purchasing a Las Vegas home for the medical dean and kicking around the idea for a $220 million academic medical center at UNLV.

Ultimately, regents decided upon creating a separate medical school for Southern Nevada that could educate high-quality physicians, spur new medical businesses and make Las Vegas a mecca for medical tourism.

“We’ve known for a long time that it is imperative that we build the health care capacity of Southern Nevada,” UNLV’s Smatresk said in a statement. “This collaborative agreement is a substantial step forward and offers a path that effectively utilizes the resources of two great institutions to address our critical needs in health care.”

The signed partnership agreement between UNR and UNLV would not only kickstart a second medical school in Nevada but help the two universities attract federal funding for medical research that would benefit northern, southern and rural communities.

“The ultimate goal is to best apply our resources and steward the investment placed in our organizations to result in improved medical care, health care services and quality of life for Nevadans,” UNR’s Johnson said in a statement.

Developing a Southern Nevada medical school will require a collaborative partnership not only between UNR and UNLV, but also among UMC, Las Vegas hospitals and the medical community. All parties must coordinate designing, financing and building a medical facility that will house clinical research and medical science training.

Building a Southern Nevada medical school will require “substantial incremental funding” from state and private sources, according to the partnership agreement. The construction cost for the UNLV medical school is expected to cost about $80 million.

The agreement calls for funding to be maintained to the UNR medical school and for more funding to create fellowships and residencies to keep physician interns in Nevada, where they are more likely to settle down and open a local practice.

“The quality of life and economic development of the state are dependent on our ability to educate more medical students, train more residents and fellows in more specialties and subspecialties, and improve the quality of care through clinical research,” Schwenk said in a statement. “This agreement is a huge step forward in accomplishing those goals.”

Earlier this year, UNLV’s Lincy Institute commissioned Tripp Umbach, a top national health care consulting firm, to conduct an economic impact study for a Southern Nevada medical school.

Tripp Umbach estimated that a UNLV School of Medicine could have a $1.9 billion total economic impact to Nevada, including the creation of 5,353 jobs and and $94 million in tax revenue by 2030. That represents six times the current economic impact of the UNR medical school, at $285 million.

The firm also recommended that UNLV medical school begin in 2016 with an initial class of 60 medical students, and grow to an incoming class of 120 students by 2030. To support its new medical school graduates and to retain them in-state, Tripp Umbach also advised that Las Vegas must create a minimum of 240 new residency positions.

In the coming months, higher education leaders will discuss the Tripp Umbach recommendations and set a timetable for the construction, programming, financing and accreditation of a UNLV medical school.

Helmets May Never Prevent Concussions

A third of Americans said they’re less likely to allow their boys to play football because they understand the head injury risks it poses, a poll showed last week. So it’s no wonder that helmet companies are racing to reassure parents that their products can lessen that risk. Meanwhile, researchers are analyzing whether helmet technology really plays a role in reducing concussions.

A current study of high school players found no differences among brand or age of helmet, said study co-author and University of Wisconsin — Madison Assistant Professor of sports medicine Alison Brooks. She will present the abstract at an American Academy of Pediatrics conference in Orlando today.

What happens to a player’s brain during hard tackles, and what can be done to keep the athletes safe?

“We were surprised that there was not a statistically significant difference in concussion incidence when comparing older age helmets (purchased in 2008 or older) to newer helmets,” she said.

But Stefan Duma, who has studied the Virginia Tech football team for years as head of the Virginia Tech-Wake Forest School of Biomedical Engineering and Sciences, says that there are big differences among helmets. His research led to a rating system, the Summation of Tests for Analysis of Risk (STAR) ratings, that ranks helmets from 1 to 5. He’s guessing that most of the players in Brooks’s study were already wearing quality helmets.

“The important thing is, there’s a big difference between the bad and the good,” he said. “There’s a big difference between a 1-star helmet and a 4-star. There’s not so much difference between a  4-star and 5-star.”

Analyzing nine years of data from Virginia Tech, in which players wore helmets equipped with sensors, Duma’s team found an 85 percent reduced risk of concussion in a 4-star helmet vs. a 1-star helmet.

Brooks’ study will factor helmet ratings in in the next year of research, which involves 1,332 players from 36 high schools, she said. Brooks also found that brands of mouth guards probably aren’t important in terms of reducing concussion risk: Players who were generic, school-issued mouth guards actually had fewer concussions than those who wore specialized mouth guards.

Helmets alone won’t solve the concussion problem. That’s partly because of the nature of the brain’s anatomy.

“The anatomy of the brain floating freely inside the skull and the subsequent mechanism of injury will make it difficult to significantly reduce concussion risk using helmet technology alone,” Brooks said. “I think focus could be better spent on rule enforcement and coaching education on tackling technique to limit/avoid contact to the head, perhaps limiting contact practices, and behavior change about the intent of tackling to injure or ‘punish’ the opponent.’”

Duma agrees that future technology probably won’t change concussion rates in football much more. Current technology in football helmets is “about as good as we can get,” he said.

Still, sports in which helmets haven’t been focused on to the same extent may have more room to benefit. Duma’s team will present a rating system for hockey helmets this fall, and they plan on rating lacrosse helmets next. And new technology, perhaps in the form of a headband, may be on the horizon for youth soccer.

Contaminated spices can cause salmonella

Imported spices are contaminated at a rate twice that of other imported food, according to an analysis by the Food and Drug Administration.

Not only were 7 percent of the spices it examined contaminated with the toxic bacteria salmonella, but 12 percent contained parts of insects, rodent hair or other filth. Salmonella is a bacterium that occurs mainly in the gut, especially a serotype causing food poisoning.

The agency’s findings “are a wake-up call” to spice producers, Jane M. Van Doren, a food and spice official at the F.D.A., told The New York Times. “It means: ‘Hey, you haven’t solved the problems.’”

During the three-year examination, the agency found more than 80 different types of salmonella. Many shipments were refused entry into the U.S.

There are almost 1.2 million annual salmonella illnesses in the United States every year, but the illness is hard to track back to spices because people don’t always keep track or remember what spices they’ve consumed. And because the amount of a spice consumed is so small, there is less of a chance of becoming ill.

How Does Salmonella Get Into Eggs?

Most of the spices eaten in the United States are imported. They come from a variety of farms and countries. Almost a quarter of spices, oils and food colors come from India. Mexico and India had the highest rates of contamination. Officials suspect that insects often find their way into spices during storage.

The FDA is “not recommending that consumers stay away from spices,” Michael Taylor, FDA’s deputy commissioner for foods, told NBC. New safety rules, he said, should help reduce the problem.
