Default Food Grade Plastic

Ontario recently introduced the new grading system along with some other added regulations. One of the new regs is that everything that contacts your sap or syrup must be food grade. This seems like common sense but there are still a lot of TSC stock tanks and sump pumps out there these days. One of the issues that has come up at various maple workshops is the question of food grade plastic. Seems many folks think that being labeled HDPE 2 makes something food grade which is incorrect. HDPE 2 is simply a recycling code denoting the type of plastic used. While most food grade plastics are made with HDPE 2 it does not necessarily mean it is food grade just because it is HDPE 2 plastic. A food grade plastic pail will be clearly marked as food grade or have the international wine glass and fork symbol on it. If it is not marked as such it is not food grade and not suitable for use in maple production.

You can buy 2 different 5 gallon plastic pails at Home Depot in the paint department. They are the same size and look almost identical. One is a couple dollars more than the other but labelled as food grade while the cheaper one is not. What is the difference other than price? When they mold the pails a releasing agent is used that allows the pail to slide off the mold without sticking. This chemical is transferred to the plastic pail and is not safe for human consumption. Dyes and other colouring will also leach from a pail unless specifically developed not to. Now add your sap to the pail and then concentrate 40 times over and you are contaminating your syrup with some pretty nasty stuff. Most of us know this information already but I wanted to get it online so I could link to it whenever this discussion comes up.
