Diaphragms of 5315 slaughter pigs from the New England states were examined for Trichinella spiralis infection between June 22 and Dec 22, 1983. 39 (0.73%) were infected. The infections were light, none exceeding 30 larvae/g of tissue with a mean of 4.7 larvae/g. Infected pigs originated from 5 of 6 New England states. The widespread occurrence of porcine trichinosis in New England indicates that the small or part-time pig farming operations frequently found in this region may be especially vulnerable to the introduction and maintenance of the parasite.
