It’s not in her jurisdiction, but Marianne H. Gravely, webmaster for the U.S. Department of Agriculture’s Meat and Poultry Hotline, says she gets calls from people with concerns about poisonous leftover onions. “I tell consumers that it is all a hoax,” she wrote in an email.
Barry E. Parsons, a food safety expert for Robson Forensic, confirms that when it comes to contamination, onions do not have “a greater propensity to absorb bacteria.” “Handled properly, whole or cut (for a day or two), they are just as safe as other foods,”
