Research – A Novel Foodborne Illness Detection and Web Application Tool Based on Social Media
Foodborne diseases and outbreaks are significant threats to public health, resulting in millions of illnesses and deaths worldwide each year. Traditional foodborne disease surveillance systems rely on data from healthcare facilities, laboratories, and government agencies to monitor and control outbreaks. Recently, there is a growing recognition of the potential value of incorporating social media data into surveillance systems. This paper explores the use of social media data as an alternative surveillance tool for foodborne diseases by collecting large-scale Twitter data, building food safety data storage models, and developing a novel frontend foodborne illness surveillance system. Descriptive and predictive analyses of the collected data were conducted in comparison with ground truth data reported by the U.S. Centers for Disease Control and Prevention (CDC). The results indicate that the most implicated food categories and the distributions from both Twitter and the CDC were similar. The system developed with Twitter data could complement traditional foodborne disease surveillance systems by providing near-real-time information on foodborne illnesses, implicated foods, symptoms, locations, and other information critical for detecting a potential foodborne outbreak.

UK records hundreds of Salmonella cases after travel to Turkey
Almost 250 Salmonella infections in the United Kingdom since the start of 2023 have been linked to travel to Turkey.
The UK Health Security Agency (UKHSA) has shared steps to reduce the risk of common infections when going abroad in summer.
The agency has detected a number of clusters of gastrointestinal illness in people returning from Turkey, the majority of whom had been to the Antalya region. Whole genome sequencing (WGS) has revealed some clusters are related, which indicates a likely common source of infection.
Between mid-January and July 19, there have been 241 confirmed cases of Salmonella Enteritidis, the majority with specimen collection dates from April onward.
Fifty-six percent of cases are male and the median age is 29 years old. Of the 93 cases for which travel information is available, people reported staying in different hotels in Turkey and most ate a variety of foods at their hotel resort as part of an all-inclusive holiday package.
UKHSA issued a warning ahead of the school summer holidays as the source of illness has not been identified. UKHSA, Turkish health authorities and other international public health agencies are involved in ongoing investigations.

USA – Breaking news: Listeria outbreak sickens 5, kills 3 in Washington
A deadly outbreak of infections from Listeria is under investigation by state and local officials in Washington.
As of late today five patients had been identified. All five required hospitalization and three have died, according to the Tacoma-Pierece County Health Department.
All of the patients are or were in their 60s or 70s and all had weakened immune systems, according to the health department, which is working with Washington State Department of Health (DOH) and Thurston County Public Health and Social Services.
The Tacoma News is reporting that “genetic fingerprinting results (whole genome sequencing) indicate that these patients likely have the same source of infection. Patients became ill between February 27 and June 30, 2023.”
State and local public health officials have not yet discovered a source for the bacteria. They are interviewing patients and their representatives to develop a profile.
The state of Washington generally logs 10 to 25 cases of Listeria infection annually, according to the Tacoma health department.

Symptoms of Hepatitis A
Illness usually occurs within 15 to 50 days after eating or drinking contaminated food or water. Symptoms of hepatitis A virus infection include fatigue, nausea, vomiting, abdominal pain, jaundice, dark urine, and pale stool. In some instances, particularly in children under the age of six, hepatitis A infection may be asymptomatic.

Denmark – Record number of finds of diarrhea-causing parasite in humans – Cryptosporidium
Around 800 Danes were diagnosed last year as being infected with a small single-celled intestinal parasite, Cryptosporidium, which can cause severe diarrhoea, abdominal pain, exhaustion and possibly nausea.
The many cases are a significant increase compared to previous years. The reason for the many new findings is probably primarily due to the introduction of more systematic analyzes of faecal samples at the clinical microbiology departments at the hospitals in Slagelse, Odense, Herlev and Aalborg.
“Cryptosporidium thus appears to be much more common in the population than we previously assumed. And this means that we have a diverse population of parasites whose sources and routes of infection are currently poorly understood. It is not a notifiable disease, but we follow the development through the samples that we receive,” says Rune Stensvold, senior researcher, Dept. Bacteria, parasites and fungi, Statens Serum Institut.
If you get sick from Crytosporidiosis it can last for a few weeks, but usually goes away on its own eventually, and is generally harmless.
In the past, sources of infection have been found among calves, but humans can also be infected via rodents. There are no vaccines against the parasite.

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.
