I'm finishing up a book on wild hog hunting and processing, and my research has led to a surprising discovery.
Trappers can sell the pigs to processors. the processing plants have a USDA Inspector on the premises.
Each hog being shipped to Europe is tested for trichinosis, a parasite sometimes prevalent in hogs, and very widespread in bear. I thought all hogs, both domestic and feral were carriers of trichinosis. That's not so. I learned in thousands of pounds of meat, not one has tested positive for this disease.
