USA -Patient count in Cyclospora parasite outbreak jumps by more than 200

Food Safety News

The number of patients in a large outbreak of infections from the cyclospora parasite has increased significantly, with the count approaching 600.

The Centers for Disease Control and Prevention has been tracking the outbreak since April 1. As of this week there are 581 laboratory confirmed patients. The previous update from the agency on June 22 had 317 patients listed.

“No specific food items have been identified as the source of most of these illnesses. State and local public health officials are interviewing people with cyclosporiasis to find out what foods they ate before getting sick,” according to the CDC’s outbreak update.

No specific food items have been identified as the source of most of these illnesses. State and local public health officials are interviewing people with cyclosporiasis to find out what foods they ate before getting sick.

As of July 11, 2023, a total of 581 laboratory-confirmed cases of cyclosporiasis in people who had not traveled outside the United States during the 14 days before they got sick have been reported from 32 jurisdictions, including 31 states and New York City. This is an increase of 371 cases since the last update on June 22, 2023.

Research USA – FoodNet 2022 Preliminary Data

CDC

Graphic showing progress in 2022 toward foodborne illness prevention, with changes from the 2016–2018 baseline, rates in 2022, and target rates based on Healthy People 2030 goals. Rates increased for Campylobacter, Cyclospora, Vibrio, and Yersinia and did not change for Listeria, Salmonella, Shigella, and Shiga toxin-producing E. coli. Rates for Campylobacter, Listeria, Salmonella, and Shiga toxin-producing E. coli are all higher than their established target rates.

This year’s report summarizes 2022 preliminary surveillance data. It describes 2022 incidence compared with the average incidence for 2016–2018, the reference period used for the U.S. Department of Health and Human Services (HHS) Healthy People 2030 goals. The report also summarizes cases of hemolytic uremic syndrome (HUS) during 2021.

  • In 2022, enteric (intestinal) infections monitored by FoodNet generally returned to or exceeded levels observed in 2016–2018 (before the COVID-19 pandemic).
    • Incidence of CampylobacterListeriaSalmonella, and Shigella infections did not change in 2022 compared with 2016–2018.
    • Incidence of Cyclospora, STEC, Vibrio, and Yersinia infections increased in 2022 compared with 2016–2018.
  • Campylobacter and Salmonella remain the top causes of enteric infections monitored by FoodNet.
  • Increased use of CIDTs contributed to the increased detection of infections.
  • FoodNet data show lack of progress during 2022 toward Healthy People 2030 goals for reducing foodborne illness. Concerted efforts are needed to implement effective prevention strategies to reduce disease burden.

USA – More than 100 infected in new outbreak from Cyclospora; source under investigation

Food Safety News

More than 100 people are sick in a new outbreak of infections caused by the microscopic Cyclospora parasite, but federal officials have not yet determined the source.

As of July 6, the Food and Drug Administration reported 105 patients had been confirmed in the outbreak. The agency has not reported where the patients live.

Public health officers from the FDA have begun sample collection and analysis, but the agency has not reported what food or foods are being tested.

The new outbreak of Cyclospora infections is the third the FDA has reported so far this year. One of the investigations has been closed without the agency determining the source of the microscopic parasite.

The Centers for Disease Control and Prevention is tracking another outbreak that has sickened 210 people across 22 states as of its most recent update in June. Thirty people in the outbreak have been so sick they required hospitalization.

USA – Secret 2022 Cyclospora Outbreak in Florida Sickened 161

Food Poisoning Bulletin

In the Center for Disease Control’s weekly Morbidity and Mortality Weekly Report (MMWR) for the week of July 7, 2023, a cyclospora outbreak “partially attributable” to a Caesar salad kit was revealed. This secret 2022 cyclospora outbreak sickened at least 161 people in the state of Florida.

USA- CDC – Notes from the Field: Doubling of Cyclosporiasis Cases Partially Attributable to a Salad Kit — Florida, 2021–2022

CDC

Cyclosporiasis is a gastrointestinal infection caused by a protozoan parasite, Cyclospora cayetanensis. This species is only known to infect humans and is acquired when oocysts are ingested through food or water contaminated with feces that contain the parasite. The illness was first reported in 1979, and the organism was identified and named in 1994 (1). Historically, infections were typically acquired outside of the United States or from produce that was imported into the United States (1). In recent years, the number of reported U.S. cases has been increasing: cases more than doubled from 537 in 2016 to 1,194 in 2017, and then nearly tripled, to 3,519 cases in 2018; in 2019, 4,703 cyclosporiasis cases were reported.* Recently, the parasite has been found on domestically grown produce (2), and infections have been attributed to these foods (3). Produce washing will decrease but not eliminate the parasite (1).
