Did you know?
The distinctive blue-green veins in blue cheese are created by Penicillium mold species — the same genus as the Penicillium notatum that Alexander Fleming used to discover penicillin in 1928. The mold in blue cheese is carefully cultivated and considered safe for human consumption but produces roquefortine C a mycotoxin that causes neurological symptoms in dogs. The caves of Roquefort France where Roquefort cheese is aged maintain the perfect temperature and humidity for Penicillium roqueforti growth year-round.

Even small amounts can cause tremors. The additional concerns of extreme sodium and high fat make blue cheese dangerous from multiple angles. Never give dogs any blue cheese.
