Did you know?
Tomatoes were considered poisonous in Europe for nearly 200 years after being brought from the Americas. European aristocracy ate from pewter plates high in lead — the acid in tomatoes caused lead to leach into food causing illness and death. The tomato was blamed rather than the plates. Thomas Jefferson grew tomatoes at Monticello and helped popularize them in America. The tomato is botanically a fruit — the subject of a US Supreme Court case in 1893 that ruled it a vegetable for tariff purposes.

What You Need to Know
The solanine confusion around tomatoes leads many owners to think all tomatoes are toxic — this is incorrect. Ripe red tomatoes have negligible solanine and are safe in small amounts. Green tomatoes and the tomato plant (leaves stems) are genuinely toxic. Cherry tomatoes follow the same rules — ripe only. Remove stems and leaves completely. Small amounts as an occasional treat.
