Enteritidis are the most common in the United States. Contaminated foods usually look and smell normal. Contaminated foods are often of animal origin, such as beef, poultry, milk, or eggs, but all foods, including vegetables may become contaminated. Food may also become contaminated by the unwashed hands of an infected person handling such food. Salmonella may also be found in the feces of some pets.
Reptiles are particularly likely to harbor the bacteria.
Some Salmonella bacteria have become resistant to antibiotics, largely as a result of the use of antibiotics to promote the growth of feed animals. There is no vaccine to prevent Salmonella . Therefore, to prevent infection Do not eat raw or undercooked eggs, poultry, or meat. Raw eggs may be unrecognized in some foods such as homemade hollandaise sauce, caesar and other salad dressings, tiramisu, homemade ice cream, homemade mayonnaise, cookie dough, and frostings. Poultry and meat, including hamburgers, should be well-cooked, not pink in the middle.
