Fruit drinks are a perfect fast food for today’s eat on the run lifestyle. In this study, Drosophila melanogaster flies were exposed to three local and common orange flavoured drinks (Nutri-C, Sari-C and Eve). The Drosophila melanogaster flies were fed on a Banana-Garri medium containing the test substances in varying concentrations (1, 2, 5, 10, 25, 50, 100%). The flies were bred in the media in the ratio of a male to three females, left to mate and lay eggs for six days. The numbers of offspring were counted and sex recorded. This was done until no adult eclosion in the media. There was a significant decrease (P less than 0.0001) in the progeny counts due to the medium and treatment. Also observed was the significant alteration in the sex ratio (P less than 0.05). Food products containing chemicals should be adequately tested before release into the market.
