Taiwan – Victims of banh mi food poisoning in northern Taiwan reach 520

Taiwan News

As of 10 p.m. on Tuesday (Aug. 8), the incident had sickened 520 people, with 41 hospitalized. The Food and Drug Administration will mount an inspection campaign targeting stalls and eateries selling exotic cuisines.

Among those feeling unwell after consuming food from the stall, 354 sought medical help and 32 were hospitalized, as of Monday (Aug. 7). Symptoms reported include diarrhea, stomach pain and cramps, fever, nausea, vomiting, and fatigue.

A task force has been formed to deal with the case, said the Department of Public Health of the northern city in Taiwan.

A preliminary investigation found seven out of 21 samples from the stall tested positive for Salmonella bacteria. More examinations are being conducted to identify the source of infection.

Inspectors said the eggs used to make mayonnaise had not been fully cleaned and the mayo products prepared in advance were not properly refrigerated when delivered to the stall. Salmonella infections have been a major cause of food poisoning events in Taiwan over recent years, according to the health agency.

One dead and six in hospital after mystery E.coli outbreak in UK

GB News

An E.Coli outbreak in the UK has killed one and hospitalised six others, with health officials left puzzled at the source.

The UK Health Security Agency (UKHSA) is reportedly working with the Food Standards Agency (FSA) to determine what started the outbreak, which is believed to have begun in May.

24 cases of the illness have been reported since May, including 19 in England and 4 in Northern Ireland, according to Food Safety News.

“The outbreak’s source has not yet been identified, but we are working with partners, including the Food Standards Agency, to investigate,” she added.

The strain circulating currently, is the O183, a very rare strain of E.Coli, with only 15 reported cases in the UK since 2016.

A multi-agency Outbreak Control Team (OCT) made up of the three organisations was set up.

And PHW has issued an update in relation to the investigation.

“We are currently investigating 25 confirmed and 4 probable cases of salmonella associated with a single venue in the city.” The venue has not yet been named

Norway – Outbreak of E. coli (EHEC infection)

Matportalen

This outbreak is caused by a different EHEC bacterium than the outbreak reported in June. FHI has started an outbreak investigation together with relevant municipal chief medical officers, the Norwegian Food Safety Authority and the Veterinary Institute. All the infected fell ill in July and none of them have traveled abroad.

The infected are aged < 5 to 45 years, and live in Trøndelag (4), Viken and Vestfold and Telemark. Two of them have developed the serious complication haemolytic uraemic syndrome (HUS). In addition, a further HUS case has been notified where EHEC has been detected, but we are awaiting more analyzes before we can say whether the person is infected with the same strain of bacteria as the other cases. It is not yet known what the source of infection is, but it is common for gastrointestinal bacteria to become infected through food.

– At the present time, we cannot say whether this is a limited outbreak or whether there may be new cases, says Silje Bruland Lavoll, senior physician in the section for infection from food, water and animals at the Norwegian Institute of Public Health. Investigative work can be complicated and take time, and in many cases we are unable to find the source of infection or to clarify whether it is a common source.

– We follow the situation closely and work closely with the municipal health service, the Norwegian Food Safety Authority and the Veterinary Institute, she adds.

– The Norwegian Food Safety Authority assists the Norwegian Institute of Public Health and municipal chief physicians in obtaining information from the sick persons and their relatives. Interviews are conducted about what the people have eaten and what they have been in contact with, says senior advisor Turid Berglund in the biological food safety section of the Norwegian Food Safety Authority.

Preliminary analyzes show that it is the bacterium EHEC O26:H11, which has been detected in all those infected. FHI is now working on further analyzes (whole genome sequencing) to confirm this.

USA – Irrigation water likely link in Utah E. coli Outbreak

Food Poison Journal

According to Utah health official and media, in the last two weeks, eight cases of E. coli (likely a shiga-toxin producing E. coli like E. coli O157:H7) were reported in Utah County residents, with at least five of the subjects hospitalized (likely with hemolytic uremic syndrome – HUS) due to the severity of symptoms.

Currently, all reported cases are residents of Lehi or have close ties to the city, says a statement from the Utah County Health Department.

Epidemiologists are working to identify the source of infection, it says. Preliminary investigation links the likely source of spread to using pressurized irrigation water for drinking and play.

Taiwan – 340 people fall ill from suspected food poisoning in Taoyuan

Focus Taiwan

Taipei, Aug. 5 (CNA) A Vietnamese-French sandwich stand at a traditional market in Taoyuan’s Zhongli District was forced to suspend operations Friday, after scores of its customers reported illnesses from suspected food poisoning, according to local authorities.

An inspection of the street vendor’s premises on Thursday identified 14 issues, including the temperature of the freezer, which was too high to keep food fresh, according to a press release from the city’s Department of Public Health on Friday.

In addition, there were vectors at the site, and the food ingredients were not properly covered or elevated above ground, the public health office said.

As of noon Saturday, 340 people had reported symptoms such as diarrhea, vomiting and fever after eating sandwiches purchased at the stand on Wednesday, the department said, citing reports it had received from hospitals and individuals.

The department’s inspectors have collected samples of the sauces, fillings, and other food items at the Vietnamese-French sandwich stand, as well as knives, cutting boards, and other kitchenware, which will be tested to determine the cause of the suspected food poisoning, the health office said.

If pathogenic microorganisms are found and the matter is confirmed as a food poisoning case, the operators of the food stand may be subject to a fine of between NT$60,000 (US$1,894) and NT$200 million, in accordance with the Act Governing Food Safety and Sanitation, the office said.

Research – Two Listeria monocytogenes outbreaks in a cancer centre: onsite food premises and their potential health risk to patients

BMC

This report describes two L. monocytogenes outbreak investigations that occurred in March and September of 2018 and that linked illness to a food premises located in an Ontario cancer centre. The cancer centre serves patients from across the province.

Methods

In Ontario, local public health agencies follow up with all reported laboratory-confirmed cases of listeriosis to identify possible sources of disease acquisition and to carry out investigations, including at suspected food premises. The Canadian Food Inspection Agency (CFIA) is notified of any Listeria-positive food product collected in relation to a case. The CFIA traces Listeria-positive product through the food distribution system to identify the contamination source and ensure the implicated manufacturing facility implements corrective measures.

Results

Outbreaks one and two each involved three outbreak-confirmed listeriosis cases. All six cases were considered genetically related by whole genome sequencing (WGS). In both outbreaks, outbreak-confirmed cases reported consuming meals at a food premises located in a cancer centre (food premises A) before illness onset. Various open deli meat samples and, in outbreak two, environmental swabs (primarily from the meat slicer) collected from food premises A were genetically related to the outbreak-confirmed cases. Food premises A closed as a result of the investigations.

Conclusions

When procuring on-site food premises, healthcare facilities and institutions serving individuals with immuno-compromising conditions should consider the potential health risk of foods available to their patient population.
