Avoid pesto entirely. Most recipes include garlic, which is toxic to pets and can cause anemia. High fat, salt, and dairy add further risk. Even a small smear may be unsafe due to allium content.
Pesto is an Italian sauce of basil, pine nuts, cheese, and olive oil, commonly tossed with pasta or spread on sandwiches and pizza.
Most recipes include garlic or onion. Store-bought pesto may add preservatives. Red and sun-dried tomato versions still often contain garlic.
Open jars and pesto-coated utensils are a common exposure point. Pesto is also stirred into soups, dips, and pasta leftovers where it may not be obvious.
