Organic food is produced without using most conventional pesticides; fertilizers made with synthetic ingredients or sewage sludge; or ionizing radiation.
USDA makes no claims that organically produced food is safer or more nutritious than conventionally produced food.
So, a USDA organic garden does not use amendments containing sewage sludge, and it is off-base to claim otherwise. Whether use of products containing sewage sludge constitutes a serious threat to health is another matter.
So, I’d think this Hollywood dust-up might just boil down to whether or not the players were actually intending on having an organic garden meeting the standards, or not. Did they do their homework?
Without getting into a big civics lesson, if people don’t like the regulations, they should work to get them changed. This approach is a different matter than ensuring that current regulations are being followed.
