If I had this reaction, I would be concerned as well. Since I eat pork rinds with only pork and salt, and I've never had a bad reaction, I can only sympathize and hope that you don't experience this reaction again.

Specifically, I've never had a bad reaction to any meats. To be clear, the meats that I eat are whole pastured foods without additives or chemicals. As for pork rinds, I'll continue to eat the brands that I've been eating.
