To determine if your HDPE is food grade, look for the recycling symbol with a number '2' on it. Check for any labels or certifications, such as 'USDA approved' or 'FDA approved,' which indicate it is safe for food contact. Additionally, food-grade HDPE often has a smooth surface, is free from harmful chemicals, and might be marked specifically for food storage purposes.
