Irrespective of safety, plastic fares poorly for me for taste reasons. Most soaps and detergents contain fragrances that seem to persistently bind to plastic food containers. The exception are soap products like Seventh Generation, which seem to contain less harsh/”natural” fragrances, which don’t seem to be as persistent. As it is, most foods stored in most plastic containers washed by most soaps taste like soap to me. For this reason alone, I avoid plastic where possible.
