The international symbol for food safe material is a wine glass and a fork symbol.
The symbol identifies that the material used in the product is safe for food contact. This includes food and water containers, packaging materials, cutlery etc. The regulation is applicable to any product intended for food contact whether it be made of metals, ceramics, paper and board, and plastics. Use of the symbol is more significant in products which should be explicitly identified whether food safe or not, i.e. wherever there is an ambuiguity whether the container could be used to hold food stuff.
