USA – Cyclospora outbreak in Georgia prompts public health alert

Posted on May 18, 2023 | Leave a comment

Food Safety News

Officials in Georgia are investigating an outbreak of cyclospora infections in the northwest part of the state.

The Georgia Department of Public Health Northwest Health District has not released any numbers, but it is urging people with symptoms of cyclospora infection to seek medical treatment and report any confirmed infections to local public health officials.

Georgia public health officials say their investigation is ongoing and the number of cases is expected to increase.

Cyclosporiasis causes an illness that can result in prolonged gastrointestinal distress, including watery diarrhea with frequent, sometimes explosive, bowel movements that can last for weeks. In severe cases, cyclospora infection can require hospitalization.220px-Cyclospora_cayetanensis_stained

Research – Project looks for cost-effective ways to monitor Cyclospora in agricultural water

Posted on February 21, 2023 | Leave a comment

Food Safety News

Research funded by the Center for Produce Safety is looking for a cost-effective method to detect Cyclospora in irrigation water, including a paper-based in-field water test.

The project seeks to use short strands of synthesized DNA, or aptamers, to bind to the target of interest — in this case, Cyclospora’s transmission stage.

Cyclospora cayetanensis is a protozoan parasite, that is nearly impossible to culture in the laboratory and requires complicated microscopy for detection in samples.

Lia Stanciu, Ph.D., with Purdue University, lead researcher on the project said,  “We were able to identify certain proteins on the cell membrane of Cyclospora that are unique only to Cyclospora and to which we can bind some DNA sequences.”

“We can synthesize those DNA-specific molecules. The next step would be to integrate those DNA molecules into something similar to a rapid COVID test or pregnancy test.”

Research – Studies Aim to Improve Detection, Control Methods for Cyclospora

Posted on January 14, 2023 | Leave a comment

Food Safety.Com

Two ongoing studies funded by the Center for Produce Safety (CPS) are looking to improve detection and control methods for Cyclospora cayetanensis. A complex protozoan parasite, C. cayetanensis is extremely challenging to culture in a laboratory setting, and requires complicated microscopy for detection in samples.

The first project, led by Purdue University’s Lia Stanciu, Ph.D., seeks to use “aptamers”—or short strands of synthesized DNA—to bind to C. cayetanensis. The aptamers would then be used to create a paper-based, low-cost, and easy-to-use water test for the parasite, similar to rapid COVID-19 or pregnancy tests.

The second study is exploring the use of zero-valent iron (ZVI) sand filters to remove C. cayetanensis from water, evaluating the basic principle that physical exclusion might be an option to reduce parasite burdens.

USA – Cooper’s Hawk Duval County Cyclospora Outbreak Attributed to Contaminated Basil

Posted on November 14, 2022 | Leave a comment

Food Poisoning News

The final investigation of the 2019 Cyclospora outbreak in Duval County, Florida found the most likely cause of the Cooper’s Hawk outbreak was serving food containing contaminated fresh basil – ironically, to-date Cooper’s Hawk continues to deny it served contaminated food. The Florida Department of Health of Duval County (DOH-Duval) first announced the potential outbreak on June 22, 2019 after one of Cooper’s Hawks own restaurant managers notified them of an estimated 20 employees who had became sick with gastrointestinal illness beginning on June 18, 2019. After the first report of employee infections, reports of illnesses in customers came pouring in, with a total of 153 gastrointestinal illnesses.

USA – Cooper’s Hawk Winery Cyclospora Outbreak in Jacksonville, Florida:  Victims Still Coming Forward to Seek Justice as 4-Year Statute of Limitations Approaches

Cooper’s Hawk Winery Cyclospora Outbreak in Jacksonville, Florida:  Victims Still Coming Forward to Seek Justice as 4-Year Statute of Limitations Approaches

In June of 2019, the Florida Department of Health in Duval County (DOH-Duval) was notified of an outbreak of gastrointestinal illness (food poisoning) among employees of the local Jacksonville Cooper’s Hawk Winery – the restaurant corporate manager called in the notification. By that time, about 20 employees had become ill. On Sunday, June 23 the Regional Environmental Epidemiologist (REE) was notified by Florida Poison Information Control Network that 16 out of 17 persons who dined at Cooper’s Hawk with a group on June 11, 2019 were ill with a gastrointestinal illness.  This information was sent to DOH-Duval who began an outbreak investigation on June 24.

That same day, another individual called to report he was in a different group (24 persons) who all became ill (except one person) after eating at Cooper’s Hawk Winery in Jacksonville on June 13.

Between June 24 and July 3, 2019, a total of six independent parties contacted DOH-Duval Epidemiology to report gastrointestinal illness after they ate food from the Jacksonville Cooper’s Hawk Winery between June 11 and June 15.

On July 8, the local news media reported on the outbreak which resulted in additional patrons calling in and reporting their illnesses.

USA – Core Outbreak Table – Investigations of Foodborne Illness Outbreaks

Posted on October 27, 2022 | Leave a comment

FDA

What’s New

  • A new outbreak of E. coli O157:H7 (reference #1121) in a not yet identified product has been added to the table and traceback has been initiated.
  • For the outbreak of Salmonella Litchfield in seafood, (reference #1105), FDA issued an Outbreak Advisory on 10/19/2022.
  • Based on CDC’s epidemiological investigation of two large multistate outbreaks of Cyclospora cayetanensis (reference #1080 and #1084), ill people reported eating a variety of leafy greens before becoming sick. For both investigations, CDC, FDA, and state and local partners conducted epidemiologic and traceback investigations and collected and analyzed product and environmental samples. All samples collected were reported as negative for Cyclospora. Due to the lack of additional detail in the epidemiological data and the absence of supporting evidence collected from traceback and sample collection, FDA could not identify a specific product as the source of either outbreak.
  • For the outbreak of Salmonella Senftenberg (reference #1087) in a not identified product, one additional case was reported, the outbreak has ended, and FDA’s investigation has closed.
  • For the adverse illness event series in frozen food (reference #1076), the outbreak has ended, and the FDA investigation has closed.

UK – Man contracts Cyclospora after Mexican holiday; others report illnesses.

Posted on September 22, 2022 | Leave a comment

Food Safety News

A family in England fell sick while on holiday in Mexico with at least one of them having a confirmed Cyclospora infection.

Philip Whitmore tested positive for Cyclospora after speaking with a doctor about his symptoms.

The 61-year-old said he was shocked after being told of the diagnosis and learning how the disease can be contracted.

“I did not expect to visit a five-star hotel and contract such an illness. Being a retired chef with 40 years of professional catering experience, I did notice some concerning issues around food hygiene as the holiday went on, but I never thought that most of my family would become so unwell,” he said.
