Meat intended for freezing: EFSA assesses bacterial growth in meat before it reaches consumers EFSA assessed how bacteria grow in meat from cattle, sheep and pigs during chilling, storage and defrosting.

Our experts assessed bacterial growth in #meat intended for freezing 🥩

The way meat is stored by food business operators can affect both safety and the way meat smells and appears.

Find out how long meat can be safely stored and what this means for EU rules → link.europa.eu/PtKw9f

Deeply saddened by the passing of Kostas. He was a true leader in our field who inspired the entire community with his ideas, and energy. Beyond his immense contributions, he was a kind person. His absence leaves a great void. My thoughts are with his family and loved ones. 😢
