What is the term for contamination from package sources?

The term for contamination from package sources is referred to as migration. This occurs when substances from the packaging materials leach into the food, which can compromise food safety and quality. Migration can be influenced by factors such as the type of packaging material, the nature of the food being packaged (e.g., fatty foods may cause more migration), temperature, and storage conditions. Understanding this concept is crucial in the food industry, as it helps ensure that packaging is designed to prevent harmful substances from entering food products, thereby maintaining consumer safety and compliance with regulations.
