There aren't too many raw feeders left on here. I personal feed PMR so I don't use grinds except for tripe. If they're maintaining the 8:1:1 ratio and source locally then I say go for it. The best way to get info on the food to determine if you want to feed it, is to contact the manufacturer directly. Ask them if they source locally, ask them how they produce the product, etc. They will answer you. If they don't, then go with a different brand.
