Tomato is one of the most cultivated and consumed vegetables in the world. The main production in Kenya is by small scale farmers who may not comply with the prescribed pesticides practices. A cross-sectional survey with tomato farmers using a semi-structured questionnaire was randomly administered to 52 participants in Mwea. A number of 240 tomatoes samples were collected twice a month from three open-air markets and two supermarkets from January to June 2017 in Nairobi for pesticide residues and bacteria analyses. For further studies, sampling of freshly prepared tomato for salad from three restaurants and three hotels of the four stars’ levels and above randomly selected in Nairobi was also conducted. Lastly, consumers’ awareness of pesticide residues and bacteria on fresh tomato was assessed using a semi-structured questionnaire administered to 101 households in Kangemi in Nairobi. Results show that, 93% spray pesticides once a week on-farms; 48.5% of tomatoes analyzed had pesticide residues of which 27.27% were single, 21.21% multiple and 6.06% and 1.51% had levels above EU and Codex MRLs respectively. Tomatoes had 96% of E. coli load and same samples had 20% of non-typed Salmonella spp. Single and multiple pesticide residues were detected in freshly cooked tomato of which, omethoate and dimethoate were above EU MRLs. Sociodemographic characteristics influenced consumers’ awareness (p< 0.05) on pesticides presence on tomato. The study concludes that, farmers in Mwea were conversant with pesticides, and most of them observe good practices. Consumers were slightly more aware of bacteria’s health effects than with pesticides.
