In the wake of a voluntary 50-state recall of red, white, yellow and sweet onions originating from Thomson International Inc. in Bakersfield, CA, an increase in pathogen testing requests is anticipated by Certified Onions Inc. in Nyssa, OR.
Each of COI’s members undergoes sampling for off-label pesticide use and for maximum residue levels, and the pathogen testing is available on request.
Kay Riley, founding member and president of COI, said the pesticide residue testing service is utilized on approximately 80 percent of the onion fields in Idaho-E. Oregon’s Treasure Valley and can be made available to other onion-growing regions as well. And he said some of the area’s sheds routinely use the pathogen testing.
“I’m certain we’ll see more pathogen testing this year,” Riley said on Aug. 3, adding that E. coli 157 and Salmonella are the two microbials involved.
