TRIGOS, Ángel; RAMIREZ, Karina  e  SALINAS, Alejandro. Presence of fungal plant pathogens in fruits and vegetables and their relationship to food security. Rev. Mex. Mic [online]. 2008, vol.28, n.spe, pp.125-129. ISSN 0187-3180.

A monthly monitoring was realized during one year in fruits and vegetables expended in the city of Xalapa, Veracruz, México, in order to determine the presence of plant pathogenic fungi, as well as to determine their pathogenicity and their synthetic potential in the production of secondary metabolites toxins. Twenty seven fungal species were obtained, belonging to 18 genus. Of them, 100 % showed pathogenicity in the original product, and that behavior was verified throught Koch's postulates. However, both sellers and consumers did not realized of that pathogenicity. Literature research indicates that 60.9 % of the obtained species can be potentially producers of mycotoxins. For these reasons, it is necessary to highlight the urgency of establishing controls throught out the development of normativity which links phytosanitary diagnosis criteria with safety food in México.
