Compost/soil contamination question
Ok here we go,
My neighbor, an elderly woman has been gardening organically (or so she thought) this past growing season. It appears that she had compost delivered from the local landfill that was filled with hard (for her) to see bits of shredded plastic. I could see them plain as day once she showed me but i am believe my eyes are a bit better than hers. She came to me freaking out about it cause she is worried that the plants, their fruits and seeds will become contaminated with chemicals leeched from the plastic. I have no idea what to tell her so here i am. Any help would be much appriciated. The plants include tomatoes, peppers, greens , melons, and herbs.
