Are parasites a concern in raw or cooked meat?
No. As long as you are using USDA approved meat, it is fine. Pork had concerns with trichinosis some years ago, but this rarely seen. Cooking or heavy freezing (as is done before pork ever hits the grocery selves) is fine. Most parasites are found in the stool, and can be a concern in some wild game meat, such as wild pigs.
