Do sun-dried tomatoes or jarred pasta sauces contain toxic tomato leaves or stems?

Cats · Food safety

Last reviewed: 2026-09-05 · Reference ranges: ASPCA, Pet Poison Helpline & Merck Veterinary Manual

Short answer

The toxic compounds (solanine and tomatine) are concentrated in the leaves and stems, not the ripe fruit. Commercially prepared sun-dried tomatoes and pasta sauces are made from the fruit pulp and should not contain these plant parts. However, homemade sauces or garnishes might accidentally include stem fragments, and some artisanal products could be less rigorously processed. The risk from processed tomato products is therefore very low, but it's not zero. If your cat ate a product and later shows signs like drooling, vomiting, or lethargy, contact your vet promptly for advice.
