VERIFICATION OF GOOD PRODUCTION PRACTICES WHICH REDUCE THE RISK OF EXPOSURE OF PIGS TO TRICHINELLA

摘要

Trichinella spiralis, a nematode parasite, is found throughout the world and is capable of infecting many warm-blooded animals. Swine, fox, wolf, bear, rat, dog, cat, raccoon, skunk, opossum, and marine mammals are known reservoirs of Trichinella spiralis (1). The trichinae life cycle demonstrates how any meat eating, warm-blooded animal can acquire the organism (see Figure 1). Swine are infected with trichinae by consuming meat containing encysted larvae. Some of the most common modes of transmission to swine are: 1. Feeding uncooked garbage containing meat or meat wrappers 2. Consumption of wildlife carcasses including rats 3. Cannibalism of infected swine carcasses.
