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

Catalonia – Information on cases of botulism
4 cases of botulism have been confirmed and 2 probable with a common link of consumption in the previous days of packaged potato omelet purchased from different supermarkets. The cases have occurred in several autonomous communities.
The public health services of the communities and autonomous cities are informed to strengthen early detection in the event of the appearance of new cases with suspicion of botulism should they occur.
The Spanish Food Safety Agency (AESAN) has transferred all the available information to the contact points of the autonomous communities so that they can carry out the relevant investigations in relation to the products that could have been consumed in some of the cases.
In at least three of the confirmed cases and one of the probable ones, the company that makes the tortillas is the same. To date, no evidence has been established, neither in the products nor in the processes, that relate cause and effect. However, investigations are continuing with the collaboration of the production company.
Investigations are being carried out in relation to the possibility that there is any product on the market that is not safe or if there are deviations in the processes of production, distribution, storage or transport that justify the existence of this risk.
It is public knowledge that some distribution chain, applying the precautionary principle and in the face of the lack of certainties, has decided to withdraw from sale the products to which the epidemiological surveys have pointed, while waiting for the investigations to progress.
In any case, we want to remind consumers of the importance, especially at this time of year due to the heat, of preserving food products at the storage temperatures indicated on the labeling and following the instructions for use indicated by the manufacturers, already which guarantee the safety of products for which an expiration date is established.
The case of packaged potato tortillas is particularly important, as one can get the false impression that they are like canned foods, which have thermal stability, and keeping them unrefrigerated at the current room temperature can lead to health problems after consumption
When new information becomes available in relation to this matter, this news will be updated.

Research – Bacteriophages for the Targeted Control of Foodborne Pathogens
Abstract
Foodborne illness is exacerbated by novel and emerging pathotypes, persistent contamination, antimicrobial resistance, an ever-changing environment, and the complexity of food production systems. Sporadic and outbreak events of common foodborne pathogens like Shiga toxigenic E. coli (STEC), Salmonella, Campylobacter, and Listeria monocytogenes are increasingly identified. Methods of controlling human infections linked with food products are essential to improve food safety and public health and to avoid economic losses associated with contaminated food product recalls and litigations. Bacteriophages (phages) are an attractive additional weapon in the ongoing search for preventative measures to improve food safety and public health. However, like all other antimicrobial interventions that are being employed in food production systems, phages are not a panacea to all food safety challenges. Therefore, while phage-based biocontrol can be promising in combating foodborne pathogens, their antibacterial spectrum is generally narrower than most antibiotics. The emergence of phage-insensitive single-cell variants and the formulation of effective cocktails are some of the challenges faced by phage-based biocontrol methods. This review examines phage-based applications at critical control points in food production systems with an emphasis on when and where they can be successfully applied at production and processing levels. Shortcomings associated with phage-based control measures are outlined together with strategies that can be applied to improve phage utility for current and future applications in food safety.

Japan sees rise in food poisoning from eating raw chicken
TOKYO — Japan’s health ministry is calling for caution amid an increase in food poisoning caused by Campylobacter, a form of bacteria found in raw and half-cooked chicken.
Food poisoning cases usually rise in Japan during the damp rainy season from late May to early July. This year, experts have expressed concern about a sudden rise due to the easing of coronavirus-related restrictions, which have brought more customers back to dining out.
Once infected with Campylobacter, commonly found in raw or not fully cooked meat dishes such as sashimi, Korean “yukhoe” and lightly seared “tataki,” the bacteria can cause stomach pain and diarrhea among other symptoms. Although usually not fatal, children and the elderly are at risk of developing serious illness. In addition, the bacteria can result in Guillain-Barre syndrome (GBS), which can bring about difficulty breathing and paralysis of the limbs and face.
Around 2,000 people are afflicted with food poisoning by Campylobacter annually. Some regions, such as Kagoshima Prefecture, where chicken sashimi is part of the local cuisine, have established strict hygiene standards for the consumption of raw chicken meat, but caution is needed as about 70% of cases occur at restaurants.

Cambodia – 20 people suffered from food poisoning after having a buffet at a Siem Reap restaurant
20 people have suffered from food poisoning, with at least three of them hospitalised after buffer breakfast.
The restaurant is identified as Srey Khouch Container, located in Siem Reap city.
The victims, who ate at the restaurant yesterday, accused the restaurant owner of serving them bad food and demanded compensation, but the owner denied it and instead claimed that the victims “were eating improperly”, leading to the illness.
As of this morning, the two parties are still trying to find a solution under the supervision of the local police.

Germany sounds E. coli and HUS alert after travel to Egypt
German public health officials have warned of a spike in cases of E. coli among travelers to Egypt.
Experts from the Robert Koch Institut (RKI) said they had also seen a rise in connected cases of hemolytic uremic syndrome (HUS). HUS is a severe complication associated with E. coli infections that causes kidney failure.
Since the beginning of 2023, 31 cases of E. coli and 10 of HUS in people who were likely infected while on holiday in Egypt have been reported.
A large proportion of patients – 12 E. coli cases and six HUS cases – were recorded in May and June. They had stayed in different hotels, mainly in Hurghada, which is also the most frequent travel spot in the country.
