Factors That Influence Spinach Contamination Pre-Harvest Determined

June 20, 2013 — A team of researchers from Texas and Colorado has identified a variety of factors that influence the likelihood of E. coli contamination of spinach on farms prior to harvest. Their research is published in the July 2013 issue of the journal Applied and Environmental Microbiology.

“Microbial contamination of produce seems strongly influenced by the time since the last irrigation, the workers’ personal hygiene and the field’s use prior to planting of produce,” says first author Sangshin Park of Texas A&M University, College Station. “These factors, together with the role of weather in produce contamination should be the targets of future research efforts to design cost-effective strategies for control of produce contamination.”

E. coli contamination of spinach on farms in Colorado and Texas was 172 times more likely if the produce field was within 10 miles of a poultry farm, and 64 times more likely if irrigated by pond water, says Park. [ … continue ]
