Is trichinae a problem in pigs raised in the United States?
The Centers for Disease Control and Prevention reported that cases of human trichinellosis have declined to below 25 annually over the past several years. Only a few of these cases have been traced and associated with consumption of pork. A USDA, National Animal Health Monitoring System national swine survey conducted in 1995 reported the infection rate in United States swine to be 0.013%. Modern swine management systems have virtually eliminated trichinae as a problem in domestic pigs.
