Fermenting and plastic containers

[Katzd]

So this is my first post on the forum, so I am sorry if this is already a topic. I just ordered a mighty mini from milehigh and am thinking of getting a mash going while I wait. I know that plastic + spirits = poison, but what about during the fermentation process? I know that some plastics are ok, like those in the buckets for my beer primary fermentation, but are any food grade plastic containers ok for fermentation?
Thanks
