Cooking
Commercial preparation of pork products by cooking
requires that meat be cooked to internal temperatures which
have been shown to inactivate trichinae (Fig. 2). Using these
and other data, T. spiralis has been shown to be killed in
47 min at 52°C, in 6 min at 55°C and in less than a minute aThe USDA recommends that consumers of fresh pork cook
the product to an internal temperature of 77°C. Although
considerably higher than temperatures at which trichinae are
killed (60°C), this temperature allows for different methods of
cooking which do not always result in even distribution of
temperature throughout the meat.
No information is available on possible differential
susceptibility of the different species types of Trichinella to
heating.
