There has been a big pet food recall for foods manufactured at a Pennsylvania facility due to possible contamination with Salmonella. These do not include the higher quality brands, but I know some people on here feed things like Pedigree, PMI Nutrition, Ol Roy, etc.
Cat foods like Special Kitty are also involved in this recall.
