    Food grade and commercial food grade serve distinct purposes. While it is possible to store food in various types of plastic containers, increased awareness of the potential adverse effects of BPA has led to a preference for stainless steel in food-grade applications. Stainless steel containers for food must be seamless without any creases or corners that could trap food particles, making them easy to clean. In the context of commercial use, it's essential to avoid sharp corners and creases where food can get stuck, ensuring easy cleaning and maintenance. The emphasis in commercial food-grade containers is on rounded edges and seamless construction, eliminating welding joints, and facilitating a thorough cleaning process. Therefore, the criteria for food grade and commercial food grade differ to meet specific cleanliness and hygiene standards.

    Not necessarily. While HDPE plastics are typically food safe, they are sometimes rendered unsafe during the recycling process or with the addition of certain dyes. Objects made with HDPE plastics have to be evaluated for food safety on a case-by-case basis, so check the product specifications before using an HDPE bucket for food.

    You can purchase food grade buckets at Home Depot (such as the 5 Gallon White Pail), but the standard orange “Homer Bucket” is not rated for food. Always check the product specifications before using any bucket to store food.

    Food grade buckets must be made of plastics that are safe for contact with food and won’t contaminate the food with toxic chemicals on contact. In order for a container to be food grade, it must also be able to hold up to specific food-related uses—for instance, if a bucket or other container is intended to hold hot foods, the plastic has to be able to withstand high temperatures without melting or releasing toxins. Non-food grade buckets aren’t necessarily made of materials that are safe for direct contact with food.

    What does a 3 indicate?

    A 3 indicates the bucket is made from V or PVC (vinyl). These are food-safe, as this plastic is used in some food packaging, but it is not safe if you plan on heating food in it.

    Can I use an anti-freeze plastic drum to store water from my garden?

    It depends on how long ago it was since it was used to store anti-freeze, but just to be safe, I wouldn't recommend doing this. If you absolutely have to, then make sure to thoroughly wash the drum several times with soap and water.

  • Question
    Can I use a used plastic paint bucket to brine a turkey in a plastic bag?
    Community Answer
    Do not brine turkey in any old plastic bucket as it can leach toxins. If using cool water, you can use a number 5 in a triangle indicated on the bottom of the bucket, but not if you are using a brine with boiling water. Know what the numbers mean. Some numbers are good for dry goods storage but not liquid and vice versa.
  • Question
    Can I raise dough and keep it refrigerated in food grade tubs?
    Community Answer
    Yes, but there is a limit on the number of days dough can be stored. Your recipe or a like-kind recipe can help you determine the number of safe days to store dough. Bread dough, cookie dough, or pie crust dough have various storage needs and lengths. Cookie dough and pie crust dough can be safely frozen until needed, for example.
