Both the fresh produce industry and US public health agencies are committed to protecting the wholesomeness and safety of the nation’s food supply. And although more food safety preventive controls are being implemented by the fresh produce industry than at any time in US history, unexplained Cyclospora outbreaks continue to occur every spring and summer.
Occurring seasonally, Cyclospora outbreaks have typically been associated with produce imported from Central America. Although generally not life-threatening, cyclosporiasis causes watery diarrhea, abdominal cramps, fever and fatigue and for years, an explanation for its intermittent presence in certain fruits and vegetables has been somewhat of a mystery.
Once again, this past summer, Cyclospora struck with multiple illness clusters. And for the first time, a possibility exists that a potential source of contamination could be fresh produce grown and harvested in the US, where strict food safety practices are required by law and demanded by the industry.
Year over year, public health officials have been stymied by the mechanism that enables the single-cell Cyclospora parasite to contaminate fresh berries, herbs, vegetables, leafy greens and more, causing human illness. Today a number of basic questions are still unanswered:
- What is the source of Cyclospora outbreaks in the US?
- Why have outbreaks occurred repeatedly in spring and summer but not other months of the year?
- How and why does the organism transfer to certain fresh produce items?
- Why have most outbreaks been linked to produce imported from Central America?
- Why have investigators been unable to pinpoint how the elusive parasite comes and goes?
- What additional mitigation steps should be taken by the fresh produce industry?
- Fresh Express Panel of Third-party Experts to Focus on Cyclospora
Fresh Express, a leading supplier of value-added fresh lettuce and leafy greens in the US and Canada and the latest fresh produce company to confront an unexplained Cyclospora event, has announced the Fresh Express Blue-Ribbon Panel to study the Cyclospora problem. Comprised of independent interdisciplinary scientific experts, the Fresh Express Panel will be convened to study and report on Cyclospora’s mode of action and how it can be effectively combatted. Findings and recommendations will benefit the public, the global fresh produce industry and the wide-ranging public health and food safety communities.
Chaired by the internationally-recognized epidemiologist and infectious disease expert, Michael T. Osterholm, PhD, MPH, and coordinated by Fresh Express Director of Food Safety and Product Quality, John Gurrisi, the Panel will bring together scientists from critical fields including zoonotic disease, agronomy, cellular biology and food safety preventive controls.
The Fresh Express Blue-Ribbon Panel will assess contamination vectors of Cyclospora, potential supply chain concerns and ways for the fresh produce industry to mitigate against future outbreaks. At the same time, the Panel will provide a focused work group for collaboration and support to investigators at the US Food and Drug Administration, Centers for Disease Control and Prevention and state public health agencies who are charged with understanding and solving the outbreaks.
