When hypochlorite was used to clean the surfaces, Salmonella detection showed that although there was a reduction in the number of positive samples of all surfaces and of tomatoes handled on triclosan-treated plastic, glass and stainless steel when compared with the other procedures ( Table 2) and that no statistical difference (p > 0.01) was observed between the surfaces and tomatoes with respect to Salmonella counts ( Table 1), only stainless steel and tomatoes handled on it showed to be negative after procedure 4 ( Table 2).
