    More and more is becomming known about plastic outgassing. Many people are becomming concerned about the contamination of products stored in plastic containers. This is especially true when these containers are exposed to sunlight. This not a problem generally with containers but supers are exposed. I have been searching for info on the net but none seems available. Does anyone have info on this? Is it a concern and what do you base your answer on? Is this a concern with food-grade polypropylene?

    Usually food grade plastics are polyethelyene.

    Not sure of contamination issues.

    Food grade plastic does give off contaminates when exposed to heat or heated up. This will go into the food product and is cancer causing. Studies have been done on that and results have been posted. See attachment . If you need the article I can send it to you.

    Dan the link above didn't work- it redirected to "sciencedirect.com" so I couldn't read it.
    I don't know about sun exposure to plastic but I know that there have been internet rumours/hoaxes going around for several years now about how heating foods contained in plastic in a microwave releases dioxin and other cancer-causing chemicals into the food.
    This has been completely rebuked, (see links below) as long as the guidelines are followed. I suspect that that may be where you heard about this and related it to the heating of plastics in general. But I would be very interested to read that link if you can post the correct one. Maybe there is something more to the question of whether UV exposure releases toxic fumes from plastic.

    This is certainly a valid discussion. BUT-my concern was with plastic hive equipment under normal conditions in an apiary and shelf storage, not subjecting the equipment to extreme heat. Some people will say not to worry, but what information is that based on?
