However, the use of nitrites has sparked significant health concerns. When nitrites are exposed to high temperatures, such as during cooking, they can react with amino acids to form potentially carcinogenic nitrosamines. This has led to debates regarding the safety of consuming cured meats and the acceptable levels of nitrites in food products. Regulatory bodies, such as the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), have set limits on the amount of nitrite that can be used in food to minimize health risks while still allowing for effective preservation.
While sodium metabisulfite offers benefits, there are some safety concerns to consider. Some individuals are sensitive to sulfites, including sodium metabisulfite, which can trigger allergic reactions ranging from mild to severe. Symptoms include headaches, skin rashes, and respiratory distress, particularly in asthmatics. Due to these risks, food labeling laws in many countries require the disclosure of sulfite content in food products.
