Salmonella

What is Salmonella?

Consumers expect meat and poultry that is as free as possible from bacteria. More than twenty years of research shows that it is just not economically feasible to produce bacteria-free raw meat and poultry. That's why good sanitation and careful food handling will always be necessary to prevent bacteria on raw meat products from causing illness.

Salmonellosis is the most common foodborne illness, but it is usually preventable. Foods like eggs, raw milk, and all raw foods of animal origin may carry salmonella and other bacteria. Bacteria don't have to cause illness, though. Routine food safety practices can destroy salmonella and other bacteria.

Symptoms of Salmonellosis may lead a person to believe they have the flu. The only way to tell if you are infected is through lab tests, a process that can take several days.

The salmonella family includes about 2,000 different strains of bacteria, but only ten strains cause most reported salmonella infections. Strains that may cause no symptoms in animals can make people sick, and vice versa.

A Salmonella bacterium is a one-celled organism that can't be seen, touched or tasted. The bacteria are common in the intestinal tracts and waste of livestock, poultry, dogs, cats, rats, and other warm-blooded animals. There will always be some risk of bacterial contamination from foods of animal origin. Food safety is necessary to prevent bacteria on raw foods from causing illness.

Food Safety Tip of the Day

It's safe to bite when the temperature is right

Thermy

The only way to know food has been cooked to a safe internal temperature is to use a food thermometer. Fortunately, thermometers are high-tech and easy to use. Research shows that while cooking by "color" is frequently done, it can be misleading. Correct use of the right thermometer provides confidence that foods are adequately cooked, resulting in a safe, delicious meal.
