Food Safety Gets Trendy: Highlights from the Annual Trend Report
Food poisoning, sometimes known as foodborne illness, can happen anywhere, to anyone, and from foods we might not expect.
The Centers for Disease Control and Prevention (CDC) works with federal, state, and local partners to collect information about how many people get sick each year from different foodborne germs, or germs found in food. The Foodborne Diseases Active Surveillance Network (FoodNet) provides important data for tracking these foodborne illnesses.
Report Card for Food Safety
Each year, FoodNet reports the changes in the number of people with foodborne infections that were confirmed by laboratory tests. This information lets CDC, its partners, and policy makers know how much progress has been made in reaching national goals for reducing foodborne illness.
Highlights of the 2012 FoodNet Data
Data from FoodNet, which accounts for 15% of the US population, provide the best measure of trends in foodborne disease in the United States. Trends show if illnesses are increasing or decreasing. Overall, the 2012 FoodNet data showed a lack of recent progress in reducing foodborne infections and highlights the need for improved prevention.
- FoodNet identified 19,531 laboratory-confirmed cases of infection.
- Campylobacter was the second most common infection reported in FoodNet. Incidence of infection was 14% higher in 2012 compared with 2006–2008.
- Vibrio infections, while rare, were 43% higher in 2012 compared with 2006–2008.
- You can prevent Vibrio infections by thoroughly cooking oysters and by not exposing wounds to warm seawater.
Long-term Trends
When compared to the first three years of FoodNet surveillance (1996–1998), the 2012 data shows some clear changes:
- The overall incidence of infection of six key foodborne pathogens (Campylobacter, Listeria, Salmonella, STEC O157, Vibrio, and Yersinia) was 22% lower.
- The overall incidence of Salmonella was unchanged.
- The incidence of Vibrio infection is now 116% higher.
Recent Efforts and Next Steps
Most foodborne illnesses can be prevented. Some progress has been made in decreasing contamination of some foods and reducing illness caused by some pathogens. Recent efforts to reduce contamination of food include:
- Establishing performance standards for Campylobacter contamination of whole broiler chickens in processing plants in 2011.
- Approving more stringent time and temperature controls for oysters after harvest to prevent Vibrio vulnificus infections.
- Passing the Food Safety Modernization Act of 2011.
- The act gives FDA additional authority to regulate food facilities, establish standards for safe produce, recall contaminated foods, and oversee imported foods.
- It calls on CDC to strengthen surveillance and outbreak response.
More can be done. It is important to determine where to target prevention efforts, which requires continued collection of information to understand sources of infection, implementation of measures known to reduce food contamination, and development of new measures.

Restaurant Safety: What You Should Know
Father’s Day is right around the corner! If you’re planning to take dad out to celebrate, keep these things in mind when choosing the right restaurant for you and your family.
Food Safety Rules
The food vendors in your community, like restaurants, delis, grocery stores, and others, must follow local food safety rules. These rules are set by your city, county, district, or state. Each community may have the same or slightly different food safety rules and requirements for food vendors. All food safety rules have similar requirements about
- Safe source: Food or food ingredients come from a safe source.
- Safe temperature: Food is held at the correct cold or hot holding temperatures.
- Proper cooking: Food is cooked properly, especially foods such as meat, poultry, and pork.
- Proper handling: Food is handled to prevent cross-contamination from the environment (for example, common work areas or common utensils).
- Proper hand washing: Food handlers know how to prevent contamination, especially food handlers who may be sick with vomiting or diarrhea.
Inspections
One of the ways food safety rules protect the public’s health is through food vendor inspections. Each community’s rules may differ on
- How often food vendor inspections are conducted.
- The type of inspection form used.
- The type of grading or scoring system used to rate the safety of food vendors.
Scores
The system to rate food vendors may be a numerical score, a letter-grade score (A, B, C), or a pass/fail rating. These scores are usually shared with the public in some way, including
- Food vendor publicly posts their full inspection reports, showing all violations and inspector notes as well as the rating.
- Food vendor publicly posts only their rating and not the full inspection report.
- Food safety regulatory agency posts food vendors’ full inspection reports along with the rating on the Internet.
- Food safety regulatory agency posts only food vendors’ ratings on the Internet.
Talk to your local food safety regulators to find out whether food vendors in your area must display inspection information and what information they must display. You can find the contact information for your local food safety regulators using the Directory of State and Local Officials website. If you can’t find a food vendor’s score or inspection report, ask the manager if you can see the most recent report.
When speaking to your local food regulatory agency about the inspection report for a particular vendor, ask if they have had any recent food safety rule violations for
- Unsafe food source.
- Improper hot-holding or cold-holding of food.
- Improperly cooked food.
- Cross contamination.
- Contamination by sick workers.
Reporting Foodborne Illness
Most people don’t report their illness. Public health officials need to know about illnesses that may be caused by food so foodborne outbreaks can be identified and stopped as quickly as possible.
Report your illness to your local food safety regulator if you think a meal from a food vendor made you sick. It is especially important to report illnesses when more than one person gets sick after eating the same meal.

Deadly Listeria Food Poisoning: Who is Most at Risk?
Stephanie strived to take care of herself and her unborn baby. As an ultrasound technologist working with high-risk pregnancies, Stephanie knew more than most what could go wrong during a pregnancy. She knew the risks of Listeria--a germ that can cause food poisoning or worse--after seeing its damaging effects firsthand while working at the hospital. Unfortunately, Stephanie developed listeriosis, an infection caused by eating Listeria-tainted food. Her beautiful son, Michael, delivered brain dead and unable to breathe on his own, died two days later--another casualty of Listeria food poisoning. (Read Stephanie’s entire story.) 
Sometimes foods we love and count on for good health are contaminated with germs that cause illness and can be deadly for certain people. A new Vital Signs report on foodborne illness looks at one of the most deadly germs spread by contaminated food—Listeria—and the people it strikes the hardest.
Rare but Deadly
Although Listeria is common in the environment, it rarely causes listeriosis. About 1,600 people in the United States get sick from Listeria each year. While the infection is rare, in 2011, a new source—cantaloupes contaminated with Listeria—caused one of the deadliest foodborne outbreaks in the US.
Most at Risk
Listeria, the third leading cause of death from food poisoning, targets pregnant women and their babies, people with weakened immune systems, and those 65 years or older. Listeria hits these groups the hardest, accounting for at least 90 percent of reported Listeria infections and resulting in higher rates of hospitalization and death than most other foodborne bacteria.
- Pregnant women, fetuses, and newborn infants
Listeria can pass from a pregnant woman to her fetus or newborn. It can cause miscarriage and still birth; in newborns it can cause bloodstream infection, meningitis, or death. The risk for pregnant women is ten times higher than for the general population. For Hispanic pregnant women, the risk is 24 times higher. More consumption of Mexican-style soft cheese, like queso fresco, may explain the higher rates among Hispanics.
Listeria Outbreak: Queso fresco
(a type of soft cheese) sickened 142 people, killed 10 newborns and 18 adults, and caused 20 miscarriages. - People with weakened immune systems
A weak immune system increases the risk of Listeria infection. Many illnesses can weaken the immune system, including different kinds of cancer, HIV/AIDS, kidney and liver disease. In addition, many medicines can weaken the immune system, including steroids, cancer chemotherapy, and drugs to treat rheumatoid arthritis and other autoimmune diseases. Listeria infection occurs more often in this group than in people with strong immune systems.
Listeria Outbreak: Pre-cut celery in chicken salad served at hospitals sickened 10 people who had other serious health problems. Five of them died as a result. - Adults 65 years or older
Listeria can spread through the bloodstream to cause meningitis and often kills. The risk for those 65 years or older is four times higher than for the general population.
Listeria Outbreak: Contaminated whole cantaloupes sickened 147 people in 28 states and caused one of the deadliest foodborne outbreaks in the US. There were 33 deaths, mostly in adults over 65, reported during the outbreak.
What Can You Do?
We have made some progress against Listeria. However, we can do more to protect those at higher risk for food poisoning and make food safer for everyone. People at higher risk and those who cook for them can reduce the threat of listeriosis by following these food safety tips.
- Learn which foods are risky and do not eat these foods.
- Do not drink raw (unpasteurized) milk or eat soft cheeses made from it.
- Be aware that Mexican-style cheeses made from pasteurized milk, such as queso fresco, likely contaminated during cheese-making, have caused Listeria infections.
- Heat deli meats and hot dogs until steaming hot before eating.
- Avoid refrigerated smoked seafood unless it is in a cooked dish, such as a casserole.
- Use ready-to-eat, refrigerated foods as soon as possible. The longer they are stored in the refrigerator, the more chance Listeria has to grow.
- Refrigerate leftovers within 2 hours in shallow covered containers and use within 3-4 days.
- Be careful to avoid cross-contamination in the refrigerator or other places in the kitchen.
- Use a thermometer to make sure your refrigerator is 40°F or lower and your freezer is 0°F or lower.
CDC wants to thank Stephanie and her family and the STOP organization
for providing public awareness about those impacted by food poisoning.
