Yes, it is generally safe to use aluminum foil when handling raw meat or fish, as long as it is food-grade aluminum foil. Aluminum foil is designed to be non-toxic and resistant to corrosion, making it suitable for cooking and food preparation. However, it's important to ensure that the foil does not tear or puncture, as this could allow bacteria to contaminate the food. Additionally, avoid using aluminum foil in direct contact with acidic foods, as this can cause the foil to corrode and potentially release aluminum into the food. Always follow proper food safety guidelines when preparing and cooking with raw meats and fish.
