This “meat glue” is then often used as a binding agent in various processed products, such as sausages, canned meats, and even some cooked sausages, allowing manufacturers to create consistent texture and structure without adding additional fat or chemicals. While MRM has raised some concerns about food safety and authenticity, it is important to note that many reputable manufacturers adhere to strict quality control measures and regulatory guidelines, ensuring the end product meets consumer expectations for taste, texture, and quality.

Can glued meat result in bacterial contamination?

When it comes to food safety, a crucial concern is the potential for bacterial contamination, particularly when handling and storing meat. Glued meat, also known as mechanically recovered meat (MRM), can indeed lead to bacterial contamination if not handled and stored properly. MRM is created by mechanically separating cooked meat from bones, cartilage, and connective tissue, which can transfer bacteria from the raw meat onto the cooked product. If not cooked to the recommended internal temperature, MRM can harbor harmful bacteria like Salmonella, Listeria, and E. coli. Furthermore, insufficient refrigeration or improper storage can enable the growth of these bacteria, increasing the risk of foodborne illness. To minimize this risk, it’s essential to handle MRM products with care, ensuring they are cooked to the recommended temperature and stored at a safe temperature below 40°F (4°C). Additionally, consumers should always follow safe food handling practices, such as handling raw meat separately from ready-to-eat foods, washing hands frequently, and avoiding cross-contamination. By taking these precautions, consumers can enjoy their meals with minimal risk of bacterial contamination.
