...ts usewith beef and seafood is pending. The use of steam to briefly heat carcass surfaces to temperatures that will killE. coli O157:H7 without cooking the meat is a new, promising food safety method. Steam pasteurization has been reported to achieve up to a 1000-fold reductionof E. coli O157:H7 on treated...
