- Burger King’s A.1 Halloween Burger is reportedly turning people’s poop a bright green colour!
- The ‘black Whopper’ is a version of the fast food chain’s signature burger, but on a black bun. Many have taken to Twitter to say (and show!) that their poo turned green after eating the burger (using the hashtag #GreenPoop).
- It’s reported that the burger contains less than 1% food dye (namely D&C Red #40 and FD&C Blue #1).
- According to the FDA, the dyes are safe for consumption with similar reactions seen when people eat large amounts of green vegetables.
