In Jonathan Safran Foer's book, "Eating Animals," he outlines the strict standards for animals producing meat, milk, and eggs labelled as organic. These animals must be fed organic feed, which does not involve most synthetic pesticides or fertilizers. There's also a traceability requirement that ensures the source of the animal products can be verified.

Additionally, organic animals cannot receive antibiotics or growth hormones, and they must have outdoor access. These regulations aim to promote more humane and environmentally friendly farming practices, ultimately addressing consumer concerns about animal welfare and food safety.
