Are there any safety concerns when using non-stick coatings on food covers or containers?

Non-stick coatings on food covers or containers are generally safe when used as directed. However, there are some concerns. High heat can cause these coatings to release potentially harmful fumes or chemicals, such as perfluorooctanoic acid (PFOA), which has been linked to health issues. It's important to avoid overheating non-stick items and to not use them in the oven or broiler. Always follow the manufacturer's guidelines for safe use and cleaning. If the coating is scratched or peeling, it's best to replace the item to prevent ingestion of the coating particles.
