How common is food poisoning?

Doreen Rodo

According to the National Restaurant Association, millions of people contract a foodborne illness each year, but many are not tested so cases go unreported. If it occurs in a restaurant, and two or more people contract the disease after eating the same food, a thorough investigation is conducted to find the source of the outbreak.

Food borne illness, better known as the dreaded food poisoning, causes almost 50 million illnesses and 3,000 deaths annually in the United States. A new study published in the September 2011 issue of Pediatrics should serve as a reminder that ice packs should be on the top of the list of back-to-school supplies to help prevent food borne illness in children.

In this study which examined the lunchboxes of over 700 preschoolers, researchers found that over 90 percent of the perishable items in the lunch box were at unsafe temperature by the time the children were chowing down on their packed lunch. Even more shocking, the researchers uncovered that almost 40 percent of the lunch boxes didn’t have an ice pack.

Perishable foods such as yogurt, meats, and cut up fruits and vegetables, should remain chilled at 40 degrees F or below to slow down the pathogens’ ability to multiply to dangerous levels. Perishables that are left out at room temperature for more than 2 hours should be tossed as they are unsafe to consume.

Insulated lunch boxes, along with a frozen ice pack, is your best bet to help keep your edibles at a safe temperature until lunchtime. According to the Academy of Nutrition and Dietetics, a frozen individual juice box can help serve as a cold pack, and you should instruct a child to throw away all perishable leftovers after lunch. The inside and outside of the lunch box should also be thoroughly cleaned with hot soapy water and rinsed clean in between uses.

Food poisoning affects one in six Americans each year. And up to 70 percent of the cases of food poisoning originate not in a manufacturing plant (as in many well-documented cases of contaminated produce), but in the kitchen.

One of the leading causes of illness is food poisoning. There are over 1.4 million cases of Salmonella poisoning in the US each year—most are from food. And there are about 74,000 cases of E coli poisoning per year—59,000 of which are from food. The cost of medical care for food poisoning? $378 million for E coli alone and $152 billion—you read that right—a year total for foodborne disease in the United States.

We've all been there: face down in the toilet trying to expel the toxic remains of last night's dinner. Ugly scene, ugly feeling, ugly clean-up duty. Many people assume that their so-called bug comes from a virus, but the truth is that a lot of intestinal tumult comes from something even scarier—food poisoning.

Why do people often blame the heaves on some alleged 24-hour bug or flu? One reason is that it often takes from 24 to 72 hours for food-borne illnesses to take effect, so you don't associate a potentially bad food with sickness; salmonella can take three days for symptoms to appear, and E. coli can take up to eight days.

Other various misconceptions about food poisoning also contribute to the confusion. For example, many people believe that spoiled food will always have a bad smell and taste (in fact, germs and toxins don't change the taste), and still many others think that food made at home is safer than restaurant food (not true).

No wonder that for every reported case of food poisoning, there are anywhere from 20 to 100 that go unreported, according to the Center for Disease Control. There are 50,000 to 2.5 million severe cases of food poisoning every year—and 2,500 deaths.
