For anything sold there should be a website that citizens can obtain a “Truth Slip” on that product (food or otherwise) for a full list of ingredients.
Right now if certain things fall below a threshold set by the FDA, it does not have to be disclosed. That should be abolished and 100% of ingredients have to be disclosed. There is no “safe” amount of poison, hidden hormones, etc. in food and toiletries.
In the name of full disclosure, the place producing the product should be required to submit their ingredients, study, party that conducted the research, etc.
Via the app/website, if a product is not found by the consumer, then you could mark it as such or submit a “ticket” and that company would have to provide it.
