Sumac is a tangy red-purple spice made by drying and grinding berries from Rhus species, most commonly Rhus coriaria, and is used to add lemon-like acidity to meats, grains, salads, and dips. It contributes flavor more than major nutrition, but concentrated sour spice and salt-heavy blends may irritate digestion in sensitive pets. For pets, sumac is not a needed food, and any exposure should stay at tiny plain culinary traces.
In home kitchens, sumac appears as fine powder, coarse flakes, or premixed blends such as zatar. Many blends add salt and may include alliums such as onion or garlic, which create more risk than plain sumac alone. Prepared dishes also often pair sumac with oil, grilled fats, or acidic marinades that may worsen stomach upset after scavenging leftovers.
Name confusion is common because culinary sumac is different from poison sumac plants found in the wild. Pets may encounter the spice in rubbed meats, rice bowls, roasted vegetables, and dip toppings. Keep spice jars and seasoned scraps out of reach, and monitor for vomiting, diarrhea, drooling, or appetite changes after known ingestion.
