I have been doing some research on what is considered food safe containers.  I had an inspector question our containers that we are using to store our spices in.  From the research I have done I think what I am using is ok.  Here is what I found.......


As a general rule, the numbers that are safe for use with food are 1, 2, 4, and 5.
  • The best type of plastic for use in long-term food storage is high-density polyethylene (HDPE), which is indicated by the "2" symbol. ...
  • Other types of plastic acceptable for food storageinclude PETE, LDPE, and polypropylene (PP).


So, if my container has the PP and 5 on the bottom it should be safe right?

I would look for a statement from the container manufacturer saying they are food grade. This would satisfy the FDA.


To be completely FDA compliant, the component end user must also be certain that

  • The material is used within the recommended safe temperature range
  • The material is safe for the type of food that it is in contact with (fat percentage, acidity, moisture content and so on)
  • The material will physically hold up to the environment it will be used in, including cleaning and sanitizing
