Officials are recalling certain brands of dog food made in Louisiana after a toxin that killed many of the animals 5 years ago was found in the brands. Agribusiness company Cargill says its recalling a year's output of River Run and Marksman brands that were made at one of their plants between December of last year and now. Aflatoxin killed more than 75 dog deaths in 2006. The toxin can cause liver failure or death. So far, Cargill says no illnesses have been reported. The toxin is sometimes a by-product of a corn fungus which is often found in the southern United States. A list of the recalled products is on the Cargill web site.
