USA – CDC – Cyclosporiasis Illnesses in the United States, 2023

Posted on July 20, 2023 by | Leave a comment

CDC

CDC, along with state and federal health and regulatory officials, monitor cases of cyclosporiasis acquired in the United States in the spring and summer months to detect outbreaks linked to a common food source. Cyclosporiasis is a diarrheal illness caused by a parasite called Cyclospora cayetanensis.

Fast Facts

  • Illnesses: 581
  • Hospitalizations: 55
  • Deaths: 0
  • States reporting cases: 31
  • Investigation status: Active (first posted on May 25, 2023)

Cyclosporiasis illnesses are reported year-round in the United States. However, during the spring and summer months there is often an increase in cyclosporiasis acquired in the United States. The exact timing and duration of these seasonal increases in cyclosporiasis can vary, but reports tend to increase starting in May. This year, cases were reported starting in April. It is too soon to tell if this timing indicates a change in the seasonality of cyclosporiasis in the United States.

In previous years, the reported number of cases peaked between June and July, although cases can be reported as late as September. The number of infections or hospitalizations and the number of identified outbreaks linked to a common source also vary from season to season.

USA – 10 in Washington, California, Oregon and Hawaii linked to Hepatitis A tainted Strawberries

Posted on July 20, 2023 by | Leave a comment

Food Poison Journal

CDC, state public health and regulatory officials, and the U.S. Food and Drug Administration are investigating an outbreak of hepatitis A linked to frozen organic strawberries imported from certain farms located in Baja California, Mexico, by a common supplier. Frozen organic strawberries may be sold to a variety of retailers under multiple brand labels. Traceback and epidemiological investigations show that people with outbreak-associated cases purchased the same retail brand of frozen organic strawberries prior to becoming ill.

As of July 18, 2023, a total of 10 outbreak-associated cases of hepatitis A have been reported from 4 states.

Illnesses started on dates ranging from November 24, 2022, to June 4, 2023. Ill people range in age from 38 to 64 years, with a median age of 56.5 years. Thirty percent of ill people are female. Of 10 people with available information, 4 (40%) have been hospitalized. No deaths have been reported.

Research -Fermenting a place in history: The first outbreak of Escherichia coli O157 associated with kimchi in Canada

Posted on July 20, 2023 by | Leave a comment

Cambridge Org

Abstract

A Canadian outbreak investigation was initiated in January 2022 after a cluster of cases of Shiga-toxin-producing Escherichia coli (STEC) O157 was identified through whole genome sequencing (WGS). Exposure information was collected through case interviews. Traceback investigations were conducted, and samples from case homes, retail, and the manufacturer were tested for STEC O157. Fourteen cases were identified in two provinces in Western Canada, with isolates related by 0–5 whole genome multi-locus sequence typing allele differences. Symptom onset dates ranged from 11 December 2021 to 7 January 2022. The median age of cases was 29.5 (range 0–61); 64% were female. No hospitalisations or deaths were reported. Of 11 cases with information available on fermented vegetable exposures, 91% (10/11) reported consuming Kimchi Brand A during their exposure period. The traceback investigation identified Manufacturer A in Western Canada as the producer. One open and one closed sample of Kimchi Brand A tested positive for STEC O157, with isolates considered genetically related by WGS to the outbreak strain. Napa cabbage within the kimchi product was hypothesised as the most likely source of contamination. This paper summarises the investigation into this STEC O157 outbreak associated with kimchi, the first reported outside of East Asia.

Taiwan – 23 suffer Salmonella poisoning at shaved ice restaurant in south Taiwan

Posted on July 19, 2023 by | Leave a comment

Taiwan News

TAIPEI (Taiwan News) — A shaved ice restaurant in Kaohsiung City has been ordered to suspend operations and pay a NT$300,000 (US$9,600) fine after 23 customers sought medical treatment for salmonella poisoning.

A woman surnamed Huang (黃) broke the news on PTT, saying that she and 12 family members went to a shaved ice shop on Liuhe Road on July 12, reported Liberty Times. After eating the shaved ice, 11 family members felt unwell and had symptoms including diarrhea, vomiting, and bloody stools, while her son was hospitalized for treatment.

On July 14, the Kaohsiung City Government Department of Health conducted an inspection of the premises and found that the floor was damaged and dirty and a trash can was not covered. The health department conducted on-site testing of the shaved ice toppings, shaved ice, and samples from the surfaces of the shaved ice equipment.

Norway – Smoked salmon and trout suspected as the source of outbreaks of Listeriosis

Posted on July 19, 2023 by | Leave a comment

Matportalen

The Norwegian Food Safety Authority is collaborating with the Norwegian Institute of Public Health , the Norwegian Veterinary Institute and relevant municipal supervisors to find the cause of the outbreak.

All four people, three women and one man, fell ill in June this year and have been admitted to hospital. All are now healthy or improving. They are aged 50-80 and live in Viken (2), Vestland and Oslo. 

The Norwegian Food Safety Authority has interviewed the persons and obtained product samples which the Veterinary Institute has analyzed (vi.no). Three out of four people report having eaten either smoked salmon or smoked trout from Troll Salmon in the time before they became ill. The outbreak bacterium was found in two packs of smoked salmon from Troll Salmon . One of the people had the packages in the freezer.

The bacterial strain in this outbreak is similar to the outbreak strain detected in an outbreak of listeriosis in 2022, where smoked salmon was the suspected source of infection (fhi.no).

– The Norwegian Food Safety Authority is in close dialogue with the business, which must ensure that they do not sell products that represent a possible health hazard for consumers. The Norwegian Food Safety Authority also monitors that the company carries out necessary investigations and implements sufficient measures in production, says Lindis Folkvord, section manager in the Norwegian Food Safety Authority’s biological food safety section.

Advice for vulnerable groups  

Most people can eat foods containing the listeria bacteria without becoming seriously ill, but susceptible people tolerate less of the bacteria.  

– It is a general advice that pregnant women, people with weakened immune systems and the elderly with a weakened general condition should eat fish and smoked fish that are as fresh as possible. This means that the product should be well within the best-before date, says Folkvord. 

Other measures to reduce the risk of listeria bacteria are to store such products in a refrigerator at 4 degrees or colder, and to wash equipment and hands after handling risk products to reduce the risk of transfer of listeria bacteria to other products.  

Risk product

Listeria is usually transmitted through food, especially refrigerated foods with a long shelf life that are eaten without heat treatment. Examples of such risk products are soft ripening cheeses and unpasteurized semi-hard cheeses, unpasteurized milk, smoked, raw and raw fish, some types of cut-up cooked meat spreads and raw meat.

Current Update

July 13, 2023

The FDA and CDC, in collaboration with state and local partners, investigated an outbreak of Salmonella Enteritidis infections linked to Chocolate Chip Cookie and S’mores Bars dough sold at Papa Murphy’s franchises and purchased before May 23, 2023.

FDA conducted a traceback investigation and identified two suppliers of interest. FDA and several state partners collected samples at both suppliers, and state partners also collected retail samples at several Papa Murphy’s stores. All samples collected were reported as negative for Salmonella contamination. As of July 13, 2023, CDC announced that the outbreak is over. CDC reports a total of 26 illnesses in six states. The last illness onset was May 22, 2023. FDA’s investigation is complete.

In response to this investigation, Papa Murphy’s notified franchise owners nationwide and stopped selling all Chocolate Chip Cookie dough and S’mores Bars dough at all stores and stopped using unprepared dry cookie dough mixes dating back through April 2023 to ensure any potentially contaminated ingredients are not used. As of July 13, 2023, Papa Murphy’s has not restarted sales of cookie dough. Additionally, the firm is reviewing their dessert menu items and labels to further enhance instructions to consumers to emphasize that their products are not intended to be eaten raw.
