Aged meat does not pose any additional risks compared to fresh meat if it is aged under controlled conditions, EFSA experts concluded in a scientific opinion released today.
Meat ageing is a process during which microbes and enzymes act upon the meat to break down the connective tissue, thereby tenderising the meat and giving it a richer flavour. This can be done through two main methods: wet ageing and dry ageing. Wet ageing is used for beef, pork and lamb that is stored and refrigerated in a vacuum package, while dry aged beef is refrigerated without packaging which results in a dry surface that is cut off before preparation.
“Aged meat has risen in popularity in recent years among the food industry and restaurants yet until now there has been a lack of knowledge about its safety. EFSA’s advice contributes to fill that gap and provides a solid scientific basis for food business operators to produce aged meat that is safe,” said the Chair of EFSA’s Panel on Biological Hazards, Prof Kostas Koutsoumanis.
There are no additional risks involved provided that the specific combination of time and temperature identified in the scientific opinion are observed during the ageing process, said EFSA’s experts. For example, dry aged beef can be considered as safe as fresh beef if ageing is done for up to 35 days at a temperature of 3°C or lower.
