Since we've broadened the scope, I'll add some food for thought with
a little info about trichinosis caused by Trichinella species.
Georgi's Parasitology for Veterinarians says that carnivores and
omnivores become naturally infected through predation, cannibalism
and carrion feeding. Human trichinosis usually results from eating
raw or undercooked pork, bear or seal. Freezing of pork products at
-15ºC (~5ºF) for 20 days is considered to be adequate to kill T.
spiralis. Note that most home freezers are cooled to around 20ºF, so
this wouldn't begin to be adequate. An additional note in Georgi's
says that T. nativa, found in bears, can withstand storage at -20ºC
for 6 months! (ref. Pozio, et al, Journal of Parasitology 78:654-659,
1992)

[Moderator's Note: the scope was first broadened because some members were
discussing whether feeding certain wild foods would be safe or pose potential
hazards in terms of diseases and parasites, so this is on-topic and a very
useful addition to the data, but why it is on-topic may need some clarification
for those members who did not follow the earlier posts.]
