Trichinosis is one of the most serious of the parasitic diseases of man and animals. It is a disease that, although it does appear in public health statistics, receives only minor consideration from some few public health officers and but little more from many others. While tests made at autopsy indicate that 16% of the pork-eating population of the United States may have some trichina infestation, the public health statistics show there are few reported diagnosed cases and fewer reported deaths ascribed to trichinosis. Furthermore, little is known of the effect on the health of the human host in some of these infestations that do not produce typical or clear-cut diagnostic symptoms of trichinosis. What is known is that at least in the United States those cases that have been traced back to their source are generally due to the consumption of raw or inadequately cooked pork.
