Think twice before buying roadside fish

Beatrice Ngorobe selling fish at Nakuru Market. [Harun Wathari, Standard]

Dear Daktari, I have a query but I am not sure whether it is under your area of expertise. I have observed a habit where people buy fish and poultry along the roadside. I am not so sure about the safety of fish bought in Naivasha and transported all the way to be fried and eaten in Meru. During transport, such fish is dangled either on the side mirror or on the wiper where it collects dust and exhaust fumes. What is your take on this with regard to food safety?
