Actually there are still 3 companies that were shipped the contaminated rice protein that haven't been identified. The FDA and wholesaler know who they are but haven't released the info.
Also the FDA has a master list of all the recalled pet food products that you can download just go to this link and scroll down to the bottom of the page and you can download the list. The list contains 5,167 items broken down by date codes and brand and variety etc..you might want to print it out and take it with you if you shop. and if you see any of the items on the self you could tell the store manager.
