But it is not just processed food that needs food grade containers. Even the boxed zucchinis with food grade PP foil wrapping. And is it really so much different? The soil also gets wet, there is also acid in the soil, so why wouldn't a plant pot release toxins in the same way that plastic food packaging might?

Edit:

I recently watched this video https://www.youtube.com/watch?v=zTGpot7L7hA and it seems so ironic how dirty and industrial everything is, and then, all of a sudden the peas get washed and put in food grade plastic bags and we make this huge theater about sanitation.
