Tomatoes are a popular food in Tanzania, but they can contain harmful pesticide residues. These residues come from pesticides used to protect the tomatoes from pests and diseases. The pesticides can build up in the tomatoes and pose health risks to people who eat them. The levels of pesticide residues in Tanzanian tomatoes are higher than what is considered safe. This shows that there is a need to better regulate pesticide use and educate farmers on safe practices to reduce contamination.
