What causes Campylobacter enteritis?

Campylobacteriosis or Campylobacter enteritis is caused by consuming food or water contaminated with the bacteria Campylobacter jejuni. C. jejuni commonly is found in the intestinal tracts of healthy animals (especially chickens) and in untreated surface water. Raw and inadequately cooked foods of animal origin and non-chlorinated water are the most common sources of human infection (e.g., raw milk, undercooked chicken, raw hamburger, raw shellfish). The organism grows best in a reduced oxygen environment, is easily killed by heat (120 F), is inhibited by acid, salt and drying, and will not multiply at temperatures below 85 F.

What temperature does salmonella grow?

Salmonella bacteria grow at temperatures between 41 and 113 degrees F. They are readily destroyed by cooking to 160 F and do not grow at refrigerator or freezer temperatures. They do survive refrigeration and freezing, however, and will begin to grow again once warmed to room temperature.

How is salmonella spread?

Salmonella bacteria are spread through indirect or direct contact with the intestinal contents or excrement of animals, including humans. For example, they may be spread to food by hands that are not washed after using the toilet. They also may be spread to raw meat during processing so that it is contaminated when brought into the kitchen. Because of this, it is important to make sure hands and working surfaces are thoroughly washed after contact with raw meat, fish and poultry and before working with foods that require no further cooking.

What causes food intoxication?

Food intoxication results from consumption of toxins (or poisons) produced in food by bacterial growth. Toxins, not bacteria, cause illness. Toxins may not alter the appearance, odor or flavor of food. Common kinds of bacteria that produce toxins include Staphylococcus aureus and Clostridium botulinum. (See fact sheet 9.305, Botulism, for more information on its prevention.) In the case of Clostridium perfringens, illness is caused by toxins released in the gut when large numbers of vegetative cells are eaten.

What is the cause of food poisoning?

Staphylococcus and Clostridium botulinum bacteria produce a toxin (or poison) as a byproduct of growth and multiplication in food and cause food intoxication.
