High number of Yersinia enterocolitica 4/O:3 in cold-stored modified atmosphere-packed pig cheek meat

► Y. enterocolitica 4/O:3 can grow well under MA (30% CO2, 70% O2) at 6 °C. ► High number of lactic acid bacteria did not inhibit the growth of Y. enterocolitica 4/O:3. ► Raw pig head meat should not be stored under MA. ► Pig head meat should only be used for heat-treated products.
