How does the presence of ammonia in meat affect its quality and safety for consumption?

The presence of high levels of ammonia in meat can indicate spoilage and bacterial contamination, which can affect its quality and safety for consumption. Ammonia can cause off-flavors and odors in meat, making it unappetizing. Additionally, ammonia can be a byproduct of bacterial growth, which can lead to foodborne illnesses if consumed. It is important to properly store and handle meat to prevent the buildup of harmful levels of ammonia.
