Are organically-raised or grass-finished cattle less likely to have E. coli?
No. E. coli occurs naturally in healthy animals, including cattle that are fed grain, grass or those raised according to organic standards. It’s important to know that all U.S. beef is safer than ever. The incidence of E. coli O157:H7 in ground beef has declined more than 80 percent between 2000 and 2005, according to USDA.
