Facts are with any animal they have parasites. Wild ones and domesticated animals too.
That is why your vet sales dewormer for your dogs and horses.
Cattle, Swine, and Poultry have the same worms too. Do you really think all the beef cattle running around gets dewormed on monthly basis. What about a chicken farm under contract with a major supplier that pays them less than .05 perlb. the grower can not hardly afford to feed them let alone give the Ivermec.
One good thing is that most parasites typically attack the digestive trac.
If you like eatingChitlins you should boil them first. Other than that you will probobly never ever get any worms or other parasites from the muscle tissue.
