Right now, the best idea I can think of is to keep abreast of the news regarding pet food recalls.
Go to Google News and type in pet food recall (and possibly the brand you feed and want to monitor) and click “Search News”.
The search results are usually presented by relevance, but you can request that the most recent stories be presented first. (Google constantly updates with just-posted news stories). These options are toward the upper right of the screen.
Please check frequently for updates, read critically and from multiple sources, and please share the info with friends, neighbors and co-workers.
May your pets be well-fed and healthy.
