Ignoring the labels can lead to very serious illnesses. Here are some recent examples.
Unrefrigerated Soup Tied to Botulism Cases
Recently, a consumer in the South bought a plastic container of soup from a salad bar in a supermarket. It was sold cold and clearly labeled:
HEAT & SERVE / KEEP REFRIGERATED
The soup sat unrefrigerated for a day or two before it was heated. The consumer tasted it and threw it out because it was "sour." Despite having eaten very little of the soup, the consumer ended up in the hospital with botulism.
A similar case occurred in the Midwest last February. The consumer bought soup in a pack of two-plastic containers. It also was sold cold, and the labels also said to keep it refrigerated. One container was consumed immediately, with no ill effects. But, the consumer left the other container unrefrigerated for a week. Again, the consumer heated it, tasted it, and threw it out. And, again, that consumer also was hospitalized with botulism.
Botulism is as serious as food poisoning gets. It can result in respiratory failure and death. Even when patients survive, they may be hospitalized and on a ventilator for months, and they may suffer permanent neurological damage. So when a label says KEEP REFRIGERATED, keep the product refrigerated!
Follow the Label to Defeat Bacteria
While botulism is one of the most menacing foodborne illnesses, others are potentially quite serious as well, and product labels can help you avoid them. For example, if you pick up a package of hamburger in the grocery store, you'll find a label with "Safe Handling Instructions" which say to cook ground beef thoroughly. Don't trust the color of the meat - use a food thermometer to be sure that the internal temperature is 160 degrees Fahrenheit.
"Cook thoroughly" means that you need to cook to a safe minimum cooking temperature - 160 degrees Fahrenheit for hamburger. Don't trust the color of the meat - use a food thermometer to be sure.
What if you don't follow the label and the food is undercooked? Then you and your family are at risk of food poisoning from bacteria like E. coli. The worst type of E. coli can lead to kidney failure and even death. Children age four and under are particularly susceptible.
Microwave Labels Protect You, Too
Always read and follow the cooking instructions on frozen microwave dinners to kill any dangerous bacteria that may be in the food.
