Yes, this has been going on for a while. What gets me is that some of the packages say distributed by such & such company but don't say where they are made. I don't buy those either. When I worked for the commercial fishing company Purina and Nabisco were very particular about the fish meal they bought. I was told their pet food was fit for human consumption, not that you would want to eat it. lol
My DH was giving Hank pig ears from Tractor Supply which I didn't think was a good idea either. The cajun mentality is that if a little is good a whole lot would be better. He got him so constipated that we had to start giving him canned food for a while to get him moving again.
A couple of months ago there was a recall on Iams cat food and I was having trouble finding what I feed the house cats. There was some on the shelf at Walmart but they had entered the recall in their computers so they wouldn't sell it. I hate to change their food because I would have 6 cats hacking up presents all over.
