The U.S. Food and Drug Administration (FDA) has announced that it will investigate the safety of caffeine in food products, especially the effects of caffeine on children and teens. The FDA’s announcement comes as an increasing number of food companies have introduced food products that contain caffeine—including gum, jelly beans, hot sauce, marshmallows and Cracker Jacks.
Caffeine can be addictive, and can lead to high blood pressure and insomnia, according to the American Academy of Pediatrics (AAP). AAP discourages the use of caffeine by kids and teens. Caffeine levels vary in the new foods on the market. According to the FDA, a caffeinated version of Wrigley’s gum contains as much caffeine as four ounces of coffee, per piece. The new caffeinated gum packs each contain eight pieces of gum.
Mammography Rates Remained Steady After Change in Guidelines
The proportion of women undergoing screening for breast cancer every year did not change after U.S. Preventive Services Task Force released recommendations saying there wasn't enough evidence to support routine mammograms for women in their 40s, according to a new study published in the journal Cancer. In 2009, the Task Force changed their recommendations to state that women aged 50 to 74 should have a mammogram every other year, and screenings for women under age 50 should be evaluated by each woman with her doctor, according to individual risk factors. "When there are conflicting versions of guidelines, providers may err on the side of screening," said David Howard, a health policy researcher from Emory University in Atlanta, in an interview with Reuters.

Latest HIV Vaccine Study Halted
The National Institutes of Health halted a study testing an experimental HIV vaccine after an independent review board found the vaccine did not prevent HIV infection and did not reduce the amount of HIV in the blood. The trial, started in 2009, is the latest in a series of failed HIV vaccine trials, according to Reuters. The halted study included more than 2,500 volunteers in 19 U.S. cities. Study populations included men who have sex with men and transgender people who have sex with men. Read more on HIV.
CDC's Food Safety Report Card: Some Foodborne Illnesses Spiked in 2012
The Centers for Disease Control and Prevention (CDC) recently released the "nation’s annual food safety report card," and it shows that 2012 rates of infections from two types of foodborne bacteria—campylobacter and Vibrio—have increased significantly when compared to a baseline period of 2006-2008, while rates of most others have not changed during the same period. The data are part of the Foodborne Diseases Active Surveillance Network report. Campylobacter infections have been linked to tranmission in many foods, including poultry, raw milk and produce. These infections were at their highest level since 2000, up 14 percent since 2006-2008. Vibrio infections, often associated with raw shellfish, were up 43 percent.
“The U.S. food supply remains one of the safest in the world,” said CDC Director Tom Frieden, MD, MPH. “However, some foodborne diseases continue to pose a challenge. We have the ability, through investments in emerging technologies, to identify outbreaks even more quickly and implement interventions even faster to protect people from the dangers posed by contaminated food.” Read more on food safety.
The U.S. Department of Agriculture (USDA) is reporting that cases of foodborne illnesses surge in the summer season, likely because bacteria multiply faster when it’s warm. Key stats from the USDA:
- Americans spend $400 million on beef alone for July 4th barbecues.
- USDA research shows that 1 out of every 4 hamburgers turns brown before it has reached a safe internal temperature.
- New FDA research done in collaboration with USDA shows that only 23 percent of Americans who own a food thermometer actually use it when grilling hamburgers
- 48 million Americans (at least 1 in 6) will get sick from foodborne illness this year, resulting in roughly 128,000 hospitalizations and 3,000 deaths
USDA also offers more resources on summer grilling and on the critical steps for food safety, as well as this handy infographic as a reminder to take steps like using separate plates for raw and cooked food when grilling:
Food safety isn't the only concern this holiday. This year, the National Safety Council estimates 17,300 serious injuries and 173 traffic deaths will occur between 6:00 p.m. Tuesday, July 3, and 11:59 p.m. Wednesday, July 4. The Consumer Product Safety Commission (CPSC) is also posing some compelling July food for thought: "Would you let your kids handle a blowtorch?" According to the CPSC, sparklers burn at the same temperature as blowtorches: 2,000 degrees. In the month surrounding July 4th, 2010, the CPSC reports that 6,300 injuries were reported involving fireworks, including burns to the hands, face and head. Additional safety tips include:
- Steer clear of fireworks packaged in brown paper, as they may be professional-grade and not safe for home use.
- Never try to re-light or pick up fireworks that have not ignited fully.
- Never carry fireworks in a pocket.
The National Safety Council has additional July 4 tips on safe driving over the holiday, preventing drowning and safety hazards from hot weather.
A new survey by the MetLife Foundation and the Partnership at DrugFree.org finds that marijuana use is becoming a more acceptable behavior among teens and heavy marijuana use is now at very high levels.
Nearly half of teens (47 percent) have ever used marijuana – a 21 percent increase since 2008, and two out of every five teens (39 percent) have tried marijuana in the past year, up from 31 percent in 2008. Past-month use has increased 42 percent from 19 percent in 2008 to 27 percent in 2011. Heavy monthly use (20 or more times) rose from 5 percent in 2008 to 9 percent in 2011. The survey also found that teen boys are more frequent users of marijuana than teen girls.
Postmenopausal women who were overweight or obese and lost at least 5 percent of their body weight had a significant reduction in markers of inflammation, according to a study published in Cancer Research.
The study authors say both obesity and inflammation have been shown to be related to several types of cancer, and that the study shows that if you reduce weight, you can reduce inflammation as well.
A salmonella outbreak linked to a frozen yellow fin tuna product has now sickened 258 people in 24 states and the District of Columbia, according to an update released by the Centers for Disease Control and Prevention on Wednesday. At least 32 people have been hospitalized but no deaths have been reported.
The CDC says it is now including two types of salmonella in the outbreak strains--Salmonella Bareilly (247 cases) and Salmonella Nchanga (11 cases).
On April 16, nearly 59,000 pounds of tuna product linked to the outbreak -- labeled Nakaochi Scrape AA or AAA -- were recalled by Moon Marine USA Corp. of Cupertino, Calif. The product, which is scraped off fish bones, was sold to grocery stores and restaurants to make dishes such as sushi, sashimi and ceviche.
The Food and Drug Administration (FDA) has released a new report that details steps the agency is taking to ensure that imported food, drugs, medical devices and other regulated products meet the same standards for safety and quality as those manufactured in the United States.
According to the agency, global production of FDA-regulated goods and materials has grown significantly in the last decade:
- FDA-regulated products originate from more than 150 countries; 130,000 importers and 300,000 foreign facilities.
- Each year from 2005 through 2011, food imports have grown by an average of 10 percent, pharmaceutical products by nearly 13 percent and device imports by more than 10 percent.
- About half of all fresh fruits and 20 percent of fresh vegetables, as well as 80 percent of the seafood consumed in America, come from abroad.
- More than 80 percent of the active pharmaceutical ingredients used to make medicines are imported.
The agency says that through its international offices in Africa, Asia, Europe, Latin America and the Middle East, the FDA is increasing its knowledge base about local regulatory systems, and improving what foreign governments and industries know about FDA regulations and standards for products that will be sold in the United States. The agency says it is also collaborating to strengthen regulatory science and evidenced-based approaches to product safety and quality.

What’s in your lettuce? The U.S. Department of Agriculture (USDA) is urging Americans to embrace the increasing fondness for fresh produce by helping to avoid and remove pests that threaten crops. "We need the public's help because these hungry pests can have a huge impact on the items we use in everyday life, from the fabric in our clothing, the food on our table, the lumber used to build our home and the flowers in our garden,” says Rebecca A. Blue, Deputy Undersecretary for USDA's Marketing and Regulatory Programs.
Invasive pests are non-native species that eat U.S. crops, trees and other plants, and cost millions of dollars in losses.
While state and federal experts are working on the problem, Blue says individuals can help stem the problem by doing their part too, starting with learning tips from a new USDA website, HungryPests.com. Tips include:
- Plant carefully. Buy your plants from a reputable source and avoid using invasive plant species at all costs.
- Do not bring or mail fresh fruits, vegetables, or plants into your state or another state unless agricultural inspectors have cleared them beforehand.
- Cooperate with any agricultural quarantine restrictions and allow authorized agricultural workers access to your property for pest or disease surveys.
- Keep it clean. Wash outdoor gear and tires between fishing, hunting or camping trips. Clean lawn furniture and other outdoor items when moving from one home to another.
- Learn the signs. If you see signs of an invasive pest or disease, write down or take a picture of what you see, and then report it online.
- Speak up. Declare all agricultural items to customs officials when returning from international travel.
Public service announcements in both English and Spanish will air on television and radio throughout April and at peak times for domestic travel this summer.
According to USDA, individuals can make a difference. The Asian long-horned beetle, detected in Illinois in 1998, was declared eradicated from Illinois in 2008 with the help of local, state and federal partners and Illinois residents. The beetle was also eradicated from Hudson County, N.J.; and Islip, N.Y. And extensive efforts by USDA and its partners in California reduced European grapevine moth populations in 2011 by 99.9 percent, two years after it was detected.
Foodborne illness continues to be in the news. This week researchers from the Centers for Disease Control and Prevention (CDC) presented research at the International Conference on Emerging Infectious Diseases that found that foodborne disease outbreaks linked to foreign imports appear to have risen dramatically in 2009 and 2010.
Other findings from the research, which has not yet been published:
- Nearly half of the outbreaks involved foods imported from areas that previously had not been associated with foodborne illness.
- Between 2005 and 2010, 39 outbreaks and 2,348 illnesses were linked to imported food from 15 countries. Of those outbreaks, nearly half (17) occurred in 2009 and 2010.
- Fish was the most common source of an outbreak; spices were the second most common.
- Nearly 45 percent of imported foods linked to outbreaks came from Asia.
“As our food supply becomes more global, people are eating foods from all over the world, potentially exposing them to germs from all corners of the world, too,” says Hannah Gould, PhD, an epidemiologist in CDC’s Division of Foodborne, Waterborne and Environmental Diseases, and the lead author of the new study.
In 2002, the Council of State and Territorial Epidemiologists (CSTE) conducted its first national food safety epidemiology capacity assessment. That assessment became the basis for development of minimum performance standards to help guide state and local foodborne disease control programs. In 2010, CSTE sent states a follow-up questionnaire and the Centers for Disease Control and Prevention recently published the results of the follow-up report. The report found that to effectively address foodborne illnesses, states need:
- More epidemiologists working on food safety;
- Additional training opportunities for existing staff;
- Greater investment in information technologies to improve detection and response capacity; and
- Continued progress in building the relationship between state and local health departments and the collaborating federal agencies responsible for the control and prevention of foodborne disease.
Other barriers to investigating foodborne outbreaks include delayed notification about the outbreak, lower prioritization of investigations and insufficient funds to pay for overtime work on the investigations.
NewPublicHealth caught up with Matthew Boulton, MD, MPH, the co-author of the MMWR report, who is an associate professor of epidemiology and internal medicine in the division of infectious diseases at the University of Michigan School of Medicine, about the report.
NewPublicHealth: What did you find beyond the general results when you looked at individual measures in the report?
Matthew Boulton: States are working hard to improve their capacity to investigate foodborne outbreaks. They generally did pretty well with e. coli and salmonella, but were a little spottier when you get into other pathogens, such as norovirus and campylobacter. What would be encouraging would be uniformity with all these pathogens, but we’re just not there yet.
NPH: Why the lack of uniformity for all pathogens?
Some farmers' markets are winding down as the weather changes and crops dwindle, but in some cities the markets continue year round. A new article by News21, an investigative reporting project at several journalism schools in the U.S., reports that chickens at farmers' markets in Washington, DC harbored bacteria that could harmful if the food were not properly cooked. The investigators also found that eggs were not kept refrigerated, as required by the U.S. Department of Agriculture.
With the growing popularity of farmers’ markets, the article can serve as a reminder to vendors to learn how to grow, store and sell their products under the safest conditions, but it’s also a reminder to consumers to follow FDA guidelines for food preparation at home. That won’t prevent all food-borne infections, but it can eliminate or reduce those bacteria that respond to safe handling during preparation and storage.
As the Food and Drug Administration starts to write new food safety rules that will go into effect early next year, the New York Times followed Michael Tayor, J.D., deputy commissioner for foods, on a farm listening tour to hear suggestions and concerns of farmers who may face significant new regulations to help protect the safety of the food supply.
