Wales – Multi agency outbreak team investigating Abergavenny food poisoning incident

Abergavenny Chronicle

A food poisoning outbreak has plagued Abergavenny in recent weeks, with Public Health Wales confirming that there are 13 known cases of shigella infection within the area and a number suspected cases still being investigated.

The illness identified as shigella infection (shigellosis) is an intestinal infection caused by a family of bacteria known as shigella. The main symptom of shigella infection is diarrhoea. It is not life threatening, although in some cases it may result in hospitalisation, but symptoms usually clear up within four to five days.

A Public Health Wales spokesperson said: “Following an increase in reports of gastrointestinal illness in the Abergavenny area, Public Health Wales stood up a multiagency Outbreak Control Team with representation from Aneurin Bevan University Health Board, Monmouthshire County Council, and Powys County Council.

“We are investigating cases of shigella infection (shigellosis) associated with a single fast-food premises in the town. To date, we have identified 13 confirmed cases and a number of suspected cases are still being investigated. Appropriate public health measures have been undertaken including tracing contacts of those affected and offering testing for contacts with relevant symptoms.

Public Health Wales recommended that anyone who may be concerned about any symptoms they’re experiencing should contact 111 over the weekend and evening or contact their GP in-hours service during weekdays.

Research – Outbreak of Shigella sonnei in the EU/EEA and the United Kingdom among travellers returning from Cabo Verde


As of 16 February 2023, 10 EU/EEA countries and the UK reported and the US reported 221 confirmed Shigella sonnei infections and 37 possible cases, all with a link to Cabo Verde.

Information on possible ways of infection or common exposure have not yet been identified but investigations are ongoing in Cabo Verde. Multiple modes of transmission are plausible, and the most likely way is through food, including via infected food handlers. However, person-to-person transmission is also possible.

The S. sonnei strain in the current outbreak indicates predicted resistance to trimethoprim and streptomycin but in some cases, multidrug resistance has also been detected.

Based on the available information, many cases are reported to have stayed in all-inclusive hotels located in the region of Santa Maria on the island of Sal. The most recent cases were reported in Sweden on 19 January 2023, suggesting an ongoing moderate risk of new infections among travellers to Cabo Verde, particularly among those staying in the region of Santa Maria on the Island of Sal.

Shigellosis is a gastrointestinal infection caused by one of four species of Shigella bacteria: Shigella sonnei, S. flexneri, S. boydii and S. dysenteriae. Humans are the primary reservoirs for Shigella.

Shigellosis is caught by oral contact with material contaminated by faeces, either through direct person-to-person contact, via contaminated food or water, or via objects which have been in contact with faeces. The necessary dose for infection is small, which increases transmissibility.

Food-related outbreaks are often caused by infected food handlers, who contaminate ready-to-eat food items like salads. Waterborne infection can occur if drinking or recreational water is contaminated with faeces from an infected person.

Handwashing with soap and water is important, especially after using the toilet and before preparing or eating food. Additional care with food and drinking water when travelling abroad is also important. There is no vaccine currently available to prevent Shigella infection.

People with shigellosis should not attend school, handle food, or provide child or patient care whilst ill. Children under the age of five, food handlers, and healthcare staff should stay at home for 48 hours after their symptoms have ceased.

ECDC encourages public health authorities in the EU/EEA to increase awareness among healthcare professionals on the possibility of Shigella infections among people that recently travelled to Cabo Verde.

Together with WHO/Europe, ECDC is in regular contact with authorities in Cabo Verde to support investigations on the sources of infection and to increase awareness among healthcare professionals in the country.

Wales – Public Health Wales confirms food poisoning outbreak in Welsh town

Daily Post

Public Health Wales (PHW) has confirmed a food poisoning outbreak believed to have been caused by the shigella bacteria. The infection can cause diarrhoea, a fever, and stomach cramps.

The infection, called shigellosis, is not life-threatening but can result in hospitalisation. Symptoms typically begin one to two days after being infected by the virus and can last up to seven days.

The outbreak in Abergavenny is said to be linked to a restaurant in the town, Wales Online reports. One person claims their family and friends have been put through “horrendous sickness” as a result of contracting shigella on February 12.

In a follow-up on the outbreak of Shigellosis associated with Tamarind Tree Restaurant in Seattle, Public Health – Seattle & King County now reports 32 people reported becoming ill after eating food at the restaurant in mid-January.

Ten of the 32 people who became ill tested positive for Shigella. Six cases have confirmatory testing indicating Shigella sonnei, a species of Shigella. Symptoms among those who did not get tested are suggestive of a Shigella infection.

At this time, no employees have tested positive for Shigella.

Investigators closed the restaurant during their visit on January 24, 2023. The restaurant was required to complete a thorough cleaning and disinfection. On February 7, Environmental Health investigators revisited the restaurant to confirm proper cleaning and disinfection, and the restaurant reopened that day.

Finland joins countries with travel-related Shigella cases

Finland is the latest country to report Shigella infections in people returning from Cape Verde.

The Finnish Institute of Health and Welfare (THL) recorded eight patients with shigellosis in November and December 2022, with a history of travel to Cape Verde.

Based on typing, the strains in five of these cases match those found in other European countries. Almost all Shigella infections found in Finland originate from abroad.

During 2022, more travel-related shigellosis cases than usual were recorded in several European countries. Patients are linked by trips to Cape Verde.

Related cases have been reported by the United Kingdom, the Netherlands, France, Germany, Denmark, and Portugal.

Argentina – What is Shigella: The criminal ‘rotten meat’ bacterium

Urgente 24

Such as urgent 24 As reported, the Municipality of Berazategui made official two deaths from salmonella and shigella batteries after eating offal and other types of meat in poor condition. The subjects aged 49 and 36, without pre-existing diseases, had acute diarrheal symptoms, which required admission to intensive care with mechanical ventilation, but “died in hospital on January 12 and 17.”

As for the shigella bacterium or bacillary dysentery, it is transmitted by the fecal-oral route, just like salmonella , or by direct contact with infected people. It is endemic in tropical climates, with a higher incidence in summer, in addition to generally presenting in institutions such as nursing homes and schools due to lack of hygiene measures or contagion through food and water.

Sweden reports dozens of Shigella infections linked to travel to Cape Verde

Outbreak News Today

Folkhalsomyndigheten, or Sweden’s Public Health Agency reports 30 cases of shigella infection with a travel connection to Cape Verde have been reported in Sweden since mid-November.

Among Swedish travelers, infections with other intestinal pathogens, for example EHEC, Campylobacter, Cryptosporidium and Giardia, have also been noted. Infection with Shigella in connection with trips to Cape Verde has been a recurring problem. This and the presence of various Shigella species and other intestinal pathogens suggest contamination via food.

Shigella bacteria are found in stool, and infection is spread by eating food or drinking liquids contaminated by an infected person, or when a person touches a contaminated surface or object and then touches their mouth or puts the object into their mouth. People infected with shigellosis typically experience a fever, abdominal cramps and diarrhea which may be bloody.

Onset of shigellosis symptoms usually occurs one to two days after exposure—but may take longer—and lasts around a week. Infected people can remain contagious up to six weeks after symptoms resolve.

Most people with shigellosis recover completely without severe complications. In rare cases Shigella may cause bloodstream infections, seizures, kidney failure or arthritis.

Research – Shigellosis – Annual Epidemiological Report for 2019


Shigellosis is a relatively uncommon disease in the EU/EEA, but remains of concern in some countries and certain population groups. For 2019, 30 EU/EEA countries reported 8 448 confirmed shigellosis cases.

The overall notification rate was 2.2 cases per 100 000 population, slightly higher than in 2018. The highest notification rate was observed in children below five years of age, followed by male adults aged 25–44 years. Sexual transmission of shigellosis among men who have sex with men (MSM) is thought to have contributed to the gender imbalance characterising the disease.

Research – EU and UK record travel-related Shigella infections

Food Safety News

A multi-country Shigella outbreak in Europe has been linked to stays at some hotels in Cape Verde.

Confirmed Shigella sonnei cases have been reported in the Netherlands, Denmark, France, Germany, Portugal, and the United Kingdom.

The European Centre for Disease Prevention and Control (ECDC) said there is no information about the source of infection but given the increase in travel during the coming holiday season, new cases are likely.

However, Holiday Claims Bureau and Hudgell Solicitors in the UK have noted complaints of illness and poor hygiene standards from holidaymakers, suggesting the source could be contaminated food or water. Holiday Claims Bureau said it had been informed of sick people testing positive for Shigella.

Travelers have described symptoms such as diarrhea, vomiting, stomach cramps, and pains, which in some cases lasted until they returned home.

Anne ThomsonHudgell Solicitors’ travel litigation executive, said people can suffer as a result of a change in diet and climate.

“However, when we are alerted to situations where a number of holiday guests are affected by similar symptoms, particularly when they are not part of the same traveling group, we feel an investigation is needed to contain any wider outbreak and prevent future problems,” she said.

“Holidaymakers becoming ill having only ever eaten at the specific hotel they are staying at, and concerns raised by guests over standards of hygiene and cleanliness throughout premises, and not just in dining areas, are often red flags to potential underlying problems.”
