This really annoys me. They have an obligation, in my opinion, to ensure that their ingredient suppliers are following safe pesticide management practices. Pesticide residues in foods (if it is indeed due to treatment of the wheat, which was supposedly imported - that pesticide is banned in the US). This is a hot button issue in human foods; it's just as important here. Imagine if this was baby food! Equally stringent testing standards should be imposed.
Nutro "natural" choice, bah. Product labeling is just as misleading in animal foods as it is in human foods. Aminopterin is a folic acid derivative, so ya, it's natural - by all means use products treated with all kinds of "natural" pesticides. Of course, rotenone is technically OK in organic farming, so is pyrethrum and copper sulfate. I'm just saying they should be testing the darned crops for residues before use in the food, whether it's for humans or animals.
Imagine how contaminated these crops must have been for an individual food sample, after all that processing, to be to be 40 ppm. And, is this stuff sprayed on? I've never heard of rodent control via spraying, but then again I'm not used to dealing with rodents in fields.
Sorry for the long post, I'm pretty annoyed - I had 24 packages waiting to feed my cats. I'm practically in tears thinking about what was close to happening to me and what has happened to others. I feel so very badly for them.
