Brussels (Belgium) ‒ EFSA assessed the impact of time and temperature on the growth of spoilage bacteria in fresh beef, pork, lamb and poultry. Its experts used predictive models to compare the growth of spoilage bacteria with the growth of disease-causing (pathogenic) bacteria and concluded that spoilage bacteria grow faster under the same conditions.
EFSA had previously advised on the implications for meat safety if these two parameters – time and temperature – varied and provided several scenarios for ensuring safety of meat during storage and transport of meat. The Commission subsequently asked EFSA to consider what implications such scenarios would have for the growth of bacteria that cause meat to spoil.
Safety vs quality
“If the sole consideration was safety, policy makers would have more options on the table to pick from. However, scenarios that are acceptable in terms of safety may not be acceptable in terms of quality,” said Dr. Marta Hugas, Head of EFSA’s Biological Hazards and Contaminants unit.
Current legislation requires that carcasses are chilled to no more than 7 degrees C and that this temperature is maintained until mincing. The European Commission wants to revise this legislation to provide industry with more flexibility and asked EFSA’s scientific advice on safety and quality aspects. Experts also said that effective hygienic measures during slaughter and processing help control contamination with spoilage bacteria.
