Trichinellosis hosts: Which of the following is NOT listed as a host for the parasite that causes trichinellosis?

Trichinellosis occurs when meat contains encysted larvae, so the animals that serve as hosts are those that harbor and pass the parasite through consumption of infected tissue. Pigs are the classic domestic host, and wildlife like black bears and cougars are known hosts because they scavenge or prey on meat containing larvae. Cows are not typically listed as hosts; infections in cattle are rare and cattle are not considered a reservoir for Trichinella in standard public health references. Therefore, cows are the host not listed for this parasite.
