It is thought that only a few hundred cells of C. jejuni are capable of causing infection. Therefore, controlling this organism is best done by preventing cross-contamination between raw meats and poultry and foods that are consumed without further cooking. Pay particular attention to the proper use of cutting boards. Also, do not eat undercooked meats or poultry. The organism is easily killed by proper cooking.
Unpasteurized milk is also a major source of Campylobacter infections.
Although many states in the U.S. allow the sale of unpasteurized milk, it is not safe to drink. C. jejuni is not commonly carried by man. However, contact with household pets has been shown to be a cause of human infection. It is important to thoroughly wash your hands after handling pets. Of course, it is wise to keep pets out of the kitchen.
