UK – Advice to reptile owners following withdrawal and recall of frozen mice used as food for pets linked to Salmonella outbreak in people

FSA

The Food Standards Agency (FSA) is issuing further instructions to reptile owners following an outbreak of human salmonellosis linked to frozen mice used to feed snakes and other animals and birds.
11 December 2021
 

The FSA, along with Food Standards Scotland, Department for Environment, Food and Rural Affairs, the Animal and Plant Health Agency and the UK Health Security Agency, Public Health Wales and Public Health Scotland are advising animal keepers not to feed their pets specific batches of frozen mice.   

Since the outbreak was first reported in 2015, there have been almost 900 cases of illness. Salmonella (which causes salmonellosis) is a common bacterial disease that affects the intestines and can pass from animals to people or via consumption of contaminated food or exposure to contaminated environments and cause infection. 

This outbreak of Salmonella has been linked to specific frozen mice products and as a result, a product recall information notice detailing affected products has been issued by the FSA. The recall does not affect rats from the same supplier, however investigations are ongoing. Should concerns about the safety of rats be identified, our advice will be updated accordingly.
The FSA is instructing reptile owners and others who have a supply of the affected frozen mice to return them to the place of purchase so they can be carefully disposed of.

However, the FSA and partners are also warning people to be extra careful when handling any frozen rodents including mice product and packaging, not just the batches identified, due to the risk of salmonella from other batches linked to this recall. 
People should be extra vigilant, washing hands thoroughly with soap and water immediately after contact, when handling not just the product, but their reptiles and associated equipment and environment, due to the risk of the illness. 
Further general advice on reducing the risk of contracting Salmonella is available at https://www.gov.uk/government/publications/salmonella-reducing-infection-from-reptiles(Opens in a new window)

A government spokesperson said:

“In September this year, the FSA introduced new requirements for shops to provide a leaflet warning about the risks of Salmonella and how to keep customers safe when buying and feeding frozen mice to their reptiles. However, the outbreak continues and a full withdrawal and recall of the specific batches of frozen mice is necessary. The withdrawal and recall does not affect rats from the same supplier, however investigations are continuing, should concerns about the safety of rats be identified, advice will be updated.

Therefore, if you have the affected feeder mice product in your freezer, please return it to where you purchased it from so it can be disposed of carefully and thoroughly clean and disinfect any surfaces it has been in contact with, including your hands. We are also asking people to be extra vigilant with all frozen rodent product, however, do check the specific information about which batches are involved as retailers will not be accepting other material.”

Advice to reptile owners about feeding their pets

Snake owners and others using frozen mice as food may have concerns about maintaining their animal’s welfare, as the product withdrawal and recall will cause short term shortages. There should be sufficient mice to maintain animal welfare for all snakes and other animals, including birds that need to be fed mice, if owners adapt their current feeding routines. Detailed advice for reptile owners will be published at www.casc.org.uk/rodent-recall(Opens in a new window)

Advice to parents and guardians of children handling reptiles

Children have been particularly affected so we are urging parents and guardians to make sure everyone washes their hands thoroughly with warm soapy water every time they handle and feed frozen mice to their pets and handle their reptiles to reduce risk of becoming ill with Salmonella. Both the vivarium and the areas reptiles are able to roam could be contaminated with salmonella. Good hygiene should be observed.

If you, or other family members become ill with symptoms such as diarrhoea, abdominal pain and fever, consult your doctor or NHS 111 and inform them that you own/keep a reptile. If you have symptoms, make sure you wash your hands regularly and avoid preparing food for others. Do not go to work or school until 48 hours after symptoms have passed to reduce the chances of passing on the infection.
 

 

Research – An outbreak of food poisoning due to Escherichia coli serotype O7:H4 carrying astA for enteroaggregative E. coli heat-stable enterotoxin1 (EAST1) – Seaweed

Cambridge Org

In June 2020, a large-scale food poisoning outbreak involving about 3000 elementary and junior high school students occurred in Yashio, Saitama, Japan. A school lunch was the only food stuff ingested by all of the patients. Escherichia coli serotype O7:H4 carrying the astA gene for enteroaggregative E. coli (EAggEC) heat-stable enterotoxin 1 (EAST1) was detected in faecal specimens from the patients, and sample inspection revealed its presence in a seaweed salad and red seaweed (Gigartina tenella) as one of the raw materials. Analysis of the antibiotic sensitivity of the isolates revealed resistance to ampicillin and cefotaxime. All isolates were confirmed to be of the same origin by pulsed-field gel electrophoresis after digestion with the restriction enzyme XbaI, and single nucleotide polymorphism analysis using whole genome sequencing. To our knowledge, this is the first report of a large-scale food poisoning caused by E. coli O7:H4, which lacks well-characterized virulence genes other than astA.

Canada – Public Health Notice: Outbreak of Salmonella infections – Update

PHAC

The Public Health Agency of Canada (PHAC) is collaborating with provincial public health partners, the Canadian Food Inspection Agency (CFIA) and Health Canada to investigate an outbreak of Salmonella infections involving five provinces: British Columbia, Alberta, Saskatchewan, Manitoba and Ontario. The illnesses reported in Ontario were related to travel to Alberta and British Columbia.

The source of the outbreak has not been confirmed and the investigation is ongoing. Many of the individuals who became sick reported eating fresh avocados purchased from grocery stores or served at restaurants before their illness. Investigation findings to date have identified that these avocados have been distributed in British Columbia, Alberta, Saskatchewan and Manitoba. More information is needed to confirm the source of the outbreak. The outbreak appears to be ongoing, as illnesses continue to be reported.

The Public Health Agency of Canada is issuing this public health notice to inform residents and businesses in British Columbia, Alberta, Saskatchewan and Manitoba of the investigation findings to date so that they can make informed decisions. At this time, there is no evidence to suggest that residents in other provinces and territories are affected by this outbreak. This notice also includes important safe food handling information for Canadians and businesses that may help prevent further Salmonella infections.

This public health notice will be updated as the investigation evolves.

Investigation summary

As of December 9, there have been 79 laboratory-confirmed cases of Salmonella Enteritidis illness investigated in: British Columbia (34), Alberta (28), Saskatchewan (4), Manitoba (11) and Ontario (2). The illnesses reported in Ontario are related to travel to Alberta and British Columbia. Individuals became sick between early September 2021 and mid-November 2021. Four individuals have been hospitalized. No deaths have been reported. Individuals who became ill are between 5 and 89 years of age. The majority of cases (63%) are female.

CFIA is conducting a food safety investigation. If specific contaminated food products are identified, they will take the necessary steps to protect the public, including requesting a recall of product as required. Currently there are no Food Recall Warnings associated with this outbreak.

Research -EU One Health report: drop in reported zoonotic diseases in humans and foodborne outbreaks in 2020

EFSA

Campylobacteriosis was the most reported zoonosis in the EU in 2020, with 120,946 cases compared to more than 220,000 the previous year. It was followed by salmonellosis, which affected 52,702 people compared to 88,000 in 2019. The number of reported foodborne outbreaks also fell by 47%. These findings are based on the annual EU One Health zoonosis report, by EFSA and ECDC.

Experts acknowledged the impact of the COVID-19 pandemic in Europe in the remarkable drop in reported zoonotic diseases in humans – ranging from 7% to 53% depending on the reported disease in question – and foodborne outbreaks.

Possible factors behind the large decrease in cases include changes in health seeking behaviour, restrictions on travel and on events, the closing of restaurants, quarantine, lockdown, and other mitigation measures such as the use of masks, physical distancing and hand sanitisation.  

The next most commonly reported diseases were yersiniosis (5,668) and infections caused by Shigatoxin-producing E.coli (4,446). Listeriosis was the fifth most reported zoonosis (1,876 cases), mainly affecting people over the age of 64.

Listeriosis and West Nile virus infections were the diseases with the highest case fatality and hospitalisation rates – with most locally acquired human infections of West Nile virus reported in Greece, Spain and Italy.

The report also monitors foodborne outbreaks in the EU, events during which at least two people contract the same illness from the same contaminated food. A total of 3,086 foodborne outbreaks were reported in 2020. Salmonella remained the most frequently detected agent and caused about 23% outbreaks. The most common sources of salmonellosis outbreaks were eggs, egg products and pig meat.

The report also includes data on Mycobacterium bovis/caprae, BrucellaTrichinellaEchinococcus, Toxoplasma gondii, rabies, Q fever and tularaemia.

EFSA is publishing two interactive communication tools on foodborne outbreaks – a story map and a dashboard. The story map provides general information on foodborne outbreaks, their causative agents and implicated food vehicles. The dashboard allows people to search and query the large amount of data on foodborne outbreaks collected by EFSA from EU Member States and other reporting countries since 2015.

FDA

New Era of Smarter Food Safety - FDA's Foodborne Outbreak Response Improvement Plan Cover

Tackling foodborne outbreaks faster and revealing the root cause are essential for the prevention of future outbreaks. We have a plan to do that.

Foodborne disease remains a significant public health problem in the United States. The FDA’s Foodborne Outbreak Response Improvement Plan (FORIP), described in this document, is an important step that the FDA is taking to enhance the speed, effectiveness, coordination, and communication of outbreak investigations. (Unless stated otherwise, this report focuses exclusively on the response to human food and not animal food.)

Our ultimate goal is to bend the curve of foodborne illness in this country.
