Response to Your Membership Inquiry re: RatX 0 B. Vigon Thanks from both Laura Swanson and myself to all of the WTAG Members who provided thoughts and information on the recent inquiry from a wild bird management group regarding a product called RatX.  Here's the response that SETAC provided -- Thanks so much for inquiring about the Rat-X product.  We reached out to our experts in Wildlife Toxicology and quite a few provided information and perspectives on the ingredients in the product and its claimed mode of action. Please be aware that this commentary from SETAC experts does not constitute an endorsement or indictment of the product.  There is simply too little research on it to be definitive and in any case SETAC does not endorse or make claims about commercial products.  As you probably know from the label, the product consists of two active ingredients – corn meal gluten and salt.  The gluten is essentially a type of starch that is derived from corn processing and obviously salt is natural.  These ingredients are “Generally Recognized As Safe” (GRAS), so this is a minimum risk pesticide exempt from FIFRA (Federal law covering insecticides, fungicides and rodenticides).  According to EPA, minimum risk pesticides that meet certain criteria are exempt under section 25(b) of FIFRA.  That means the information supplied by the manufacturer (and the testing behind it) does not have to be complete or address all of the considerations applicable to more traditional pesticides.  This product is also recognized at the state level – Washington being the closest to you where I received a response.  Several of our experts commented that this product is certainly better than the anti-coagulant type active ingredients commonly found in rat poisons, which are indiscriminate and notorious for poisoning non-target birds and other wildlife, both primarily and secondarily.  That said, several experts weighed in that the EPA designation does not rule out, much less prove, there aren’t any adverse effects on non-target organisms.  One commented that this material is essentially non-nutritional toward birds and if they ate it to the exclusion of other foods, it could harm them long term.  Also, the salt content might be an issue, but estimates of ingestion dose would have to be made.  One expert indicated that he thought the likelihood of damage to raptors from eating rats who consumed the products seemed low, but this has not been researched. I hope this is helpful to you – even if possibly not as definitive as you might have hoped.   Bruce Vigon, SETAC Scientific Affairs Manager
