Natura Pet is expanding it's voluntary recall for Salmonella. However no reports as of yet have been filed by the public.
Remember that dogs can be a carrier of salmonella so if you have multiple dogs and only some of them are getting ill it does not mean that salmonella is not the problem.
There does seem to be some specialty type foods that may be used for dogs with allergies such as herring and sweet potato or salmon and peas. Be sure to check each lot if you use this product!
