Parasite search in strawberries from Irapuato, Guanajuato and Zamora, Michoacan (Mexico)

ABSTRACT

A seasonal research was carried out in Irapuato, Guanajuato and Zamora, Michaocan, Mexico, the location of the most important producers of strawberries, in order to assess fecal contamination through the findig of protozoan cysts and helminth eggs, specifically of Taenia sp eggs. Three techniques were used direct observation, flotation and sedimentation. Low numbers of protozoan cysts and only one Ascaris egg were found. What is most interesting is that no Taenia eggs were identified. Results indicate that although strawberries are contaminated with human feces, contamination is minimal
