Meat preservation and food safety practices

Guidance regarding meat preservation and safety has focused on the risks associated with improper thawing and freezing techniques.

Initial warnings highlighted that thawing frozen meat at room temperature can promote the growth of harmful bacteria like Salmonella or Escherichia coli. Because the process is uneven, the exterior may reach temperatures favorable for microbial multiplication while the center remains frozen. To prevent food poisoning, specialists recommend slow thawing inside the refrigerator to maintain safe, low temperatures.

Subsequent expert advice expanded on these practices, noting that while freezing at -18 °C stops bacterial growth, it does not preserve meat indefinitely due to moisture migration and ice crystal formation. To minimize degradation and fat oxidation, vacuum packaging is recommended over standard retail trays. For thawing, experts suggest submerging vacuum-sealed meat in cool or lukewarm water (not exceeding 40 °C) as a gentler alternative to counter-top thawing, while cautioning that hot water causes protein denaturation and moisture loss.
