Background: Fruits and vegetables are potential vehicle of transmission of intestinal parasites. The main aim of this study was to determine prevalence of intestinal parasitic contamination in fruits and vegetables sampled from Caborca region, Northwest Mexico.
Methods: A total of 400 fruit and vegetable samples were collected from unregulated open-air markets and closed (i.e., regulated) markets in Caborca region of Northwest Mexico; including melon, peach, asparagus, and grapes. Faust, Kinyoun, and Enzyme-Linked Immunosorbent Assay (ELISA) techniques were used to detect and identify the genus and species of all parasites found in the examined samples. Data were statistically analyzed using STATA/SE (version 12.0).
Results: An overall prevalence (45%) of parasitic contamination was found in the 400 fruit and vegetable samples. Endolimax nana (27.5%) and Entamoeba coli (17.5%) were the most common nonpathogenic parasites, while the most prevalent parasitic pathogens were Cryptosporidium spp. (11.7%), Cyclospora spp., (11.0%), and Blastocystis hominis (9.2%). Asparagus (31%) and grapes (38.9%) had significantly (p<0.05) higher percentages of overall and multiple parasitic contamination than melon (10.6%) and peaches (19.4%). The fresh produce from the open-air markets had significantly (p<0.05) higher overall parasitic contamination (53.5%) than those of the closed establishments (36.5%). 
Conclusion: The parasitic contamination in the fresh produce sold in the Northwest region of Mexico is a serious public health concern.
