(28)The technology used in the freezing of foods has developed significantly during recent decades and has become widely used both to improve the circulation of goods on the Union internal market, and to reduce food safety risks. However, the freezing and later defrosting of certain foods, especially meat and fishery products, limits their possible further use and may also have an effect on their safety, taste and physical quality. Conversely, for other products, especially butter, freezing has no such effects. Therefore, where a product has been defrosted, the final consumer should be appropriately informed of its condition.
