Is this food safe? I couldn't find that listed anywhere?

Based on this

http://www.seeedstudio.com/wiki/index.php?title=G1/2_Water_Flow_sensor

From what i can tell that isnt stainless or rubber seals, the rest is PA66(Nylon plastic) or POM which is another plastic.

From what i can tell PA66 is food safe unless its treated with a fire retardant, and i cant think of any reason why they would make a liquid flow sensor out of something including fire retardant.

POM from the Wiki says its FDA approved for food.
