This claim is very misleading. The link talks about a specific product that was recalled and was found to have caused salmonella. This article is not stating that dog treats cause salmonella, just one specific case where this happened. Another important thing to note is how this page is sponsored by a food safety law firm, likely meaning they advertise these claims so they can get clients. The site is also loaded with ads, possibly meaning they make articles about certain topics and products because of their advertisers. It is very important to look at not only the information presented in a claim, but the site and the way in which it is presented to the reader.
