Researchers work to help growers with FDA rules
NAMPA, Idaho — Farmers alarmed by the FDA’s proposed produce safety rule shouldn’t panic because a number of universities and organizations are preparing to help them wade through the complex proposal, a researcher involved in that effort says.
“It’s OK to hit the ‘huh?’ button but don’t hit the ‘panic’ button because a lot of groups are gearing up to provide the support system in a variety of ways,” said University of California-Davis extension research specialist Trevor Suslow, who focuses on produce quality and safety.
The U.S. Food and Drug Administration’s 152-page revised produce safety rule is difficult to understand but it’s a big improvement over the original rule, he said.
“There’s a lot of support that’s being put in place to help growers become familiar with the proposal, understand what it means and understand how to approach it within their operations,” Suslow said.
Speaking to Idaho fruit growers during the Idaho State Horticultural Society’s annual convention Nov. 20, Suslow focused his presentation on a part of the FDA proposal that would set limits on how much bacteria could be present in irrigation water.
Under the original proposal, growers whose water didn’t meet the standards would have to immediately stop using it. The revised rule allows growers whose water doesn’t meet the standards to comply through other means.
That includes establishing an interval from the last day of irrigation until harvest that would allow for potentially dangerous microbes to die off. This “die-off” provision could also apply to the time between harvest and when produce leaves storage.
Because the rate at which bacteria die off on produce is under-researched, Suslow said, he and others will ask the FDA to place that provision in a guidance document rather than the rule itself.
This would allow flexibility as more research in that area is done, he said, because “it would take an extraordinary effort to change once they’re locked in.”
“It’s a right idea,” he said, “I just think it needs to be tweaked and refined quite a bit more.”
Suslow said tests performed by researchers on well, reservoir and canal water in California and Arizona found that 95 percent of the water easily complied with the proposed water quality standards.
But in some places, such as the Treasure Valley area of Southwestern Idaho and Eastern Oregon, where some canal water is reused several times, the water would not meet the standards.
Onion growers in that area have been particularly vocal in their criticism of the proposed rule but they have been encouraged by the “die-off” provision.
The revised rule will allow growers a lot more latitude when it comes to meeting the water quality standards, Oregon State University researcher Clint Shock told the Capital Press.
But he said onion growers are still concerned about a provision of the produce safety rule that would require them to replace the wooden bins they have used for decades with plastic bins.
Replacing the estimated 1 million wooden onion boxes in Idaho and Eastern Oregon with plastic would cost about $200 million, based on estimates by OSU researchers. But OSU’s research showed no traces of E. coli bacteria on onions in wooden boxes that weren’t cleaned.
Despite this data, the FDA chose to retain the provision in its revised rule, Shock said.
“There would be a tremendous expense to replace all the bins, yet there would be no public health benefit,” Shock said.
