I saw on the news tonight that a way you can tell is to check the ingredients list of the food....if it contains wheat gluten then the safe thing to do is not use it. Apparently it's the wheat gluten tht is contaminated.
Thanx for posting a list. It is reasurring to know that we are not feeding our pet anything that would harm her .
Pets now in Canada are also getting sick. They say to watch for loss of appetite, lethargic behaviour and excessive vomitting. If caught early enough, it can be treated before they suffer from complete kidney failure. Thankfully my two little guys do not eat any of the brands affected.
