It was in the news lately about handling dog and cat food by children which has made children sick with loose bowels. (It was also making some pets sick.) They said that it was found to have e-coli. So, if you use the dog and cat food bags, I would suggest that you first wipe it down with clorox to disinfect, then wipe with water to make sure you no longer have clorox which would take the color out of material. Then it would be safe to use and more than likely, the smell would be gone also.
