Blue Cheese
ToxicVerdict
Never — the mold produces a dangerous toxin.
Toxic principle: roquefortine C
Source: ASPCA
Verdict
Blue cheeses (Roquefort, Stilton, Gorgonzola, etc.) are made using Penicillium mold cultures that produce roquefortine C, a tremorgenic mycotoxin. In dogs, this compound causes serious neurological effects including muscle tremors and seizures. Even a moderate portion can cause severe illness.
Symptoms to watch for
- • vomiting
- • diarrhea
- • high temperature
- • muscle tremors
- • seizures
What to do
If your dog ate blue cheese, contact your vet promptly. Other cheeses are less dangerous but still high in fat; plain mild cheeses in small amounts are usually OK, but avoid blue-veined varieties entirely.
