Death by Rat Urine Whenever you buy a can of coke or whatever, please make sure that you wash the top with running water and soap or, if not available, drink with a straw. A woman died after drinking a can of soda! apparently, she didn't clean the top before drinking from the can. The top was encrusted with dried rat's urine which is toxic and obviously lethal!!!!! Canned drinks and other foodstuff are stored in warehouses and containers that are usually infested with rodents and then get transported to the retail outlets without being properly cleaned. So you know what to do from now on folks........... tell someone!
