RECENT investigations have indicated that both the incidence and severity of trichinosis is waning in the United States. Studies during the 1930's demonstrated trichinous infestation in approximately 15% to 25% of autopsies,1-3 but more recently Most reported that the incidence had decreased to 5% in autopsies performed in the 1960's.4 Fatality rates approaching 50% in patients with neurologic or cardiac involvement also were common in the past, yet Gray calculated that, at present, the fatality rate in such patients was approximately 8%.5 Much of the decrease in the incidence and morbidity from trichinosis is attributable to improved feeding practices by pork raisers and greater care in the preparation of pork products. Despite this improvement, outbreaks of trichinosis still occur and result in significant morbidity. A circumscribed outbreak of trichinosis originating from a single food source was observed in Boston during September 1965. This report is presented to
