Meticulous attention to food safety is a good thing. As consumers, we like to hear that produce growers and distributers go above and beyond food safety mandates to ensure that healthy fresh fruits and vegetables do not carry bacteria or viruses that can make us sick.
But in California's Salinas Valley, some more vigorous interventions are cutting into the last corners of wildlife habitat and potentially threatening water quality, without evidence of food safety benefits. These policies create tensions between wildlife preservation and food safety where none need exist, say scientists for The Nature Conservancy, writing in the Ecological Society of America's journal Frontiers in Ecology and the Environment. The study will be published online ahead of print on Monday, May 6th, 2013.
"Farming practices for food safety that target wildlife are damaging valuable ecological systems despite low risk from these animals," said lead author Sasha Gennet.
Check the back of your bag of spinach or prepackaged salad greens, and you'll probably find that they came from the Salinas Valley. Salad is big business in California.
In the aftermath of a deadly 2006 Escherichia coli serotype O157:H7 outbreak traced to California spinach, growers and distributers of leafy greens came together to create the California Leafy Green Handler Marketing Agreement (LGMA) on best practices for the industry, enforced by third-party auditors and inspectors. The LGMA established standards for farm work hygiene, produce processing and transport, and proximity to livestock. About 99 percent of California leafy greens now come from participating farms.
But produce farmers in the Salinas Valley report pressure from some powerful buyers to take additional precautions not mandated by government or industry standards. These buyers insist that swathes of bare ground wider than a football field is long separate the leafy greens fro
