Water as contamination source of Salmonella and Escherichia coli in vegetable production in Mexico: A review

Abstract

Mexico has an extensive infrastructure that has positioned it as a power vegetable producer exporter. However, the use of wastewater represents a potential risk to agriculture, economy and human health, since they are used without the due precautions as applied in crop irrigation. In this sense, Mexico has developed a wide range of potential methods for diagnosis but is the combination of microbiological and molecular methods that most commonly are used for the rapid detection of Salmonella and E. coli in minimally processed vegetables. Further studies are needed to determine a threshold dose of pathogens in the water and to correlate the risk that tends to cause pollution of a crop and the specified edible vegetables marketed in the interior and outside of Mexico.
