UK – Almost half the adults (46%) who cook coated frozen chicken products do not always check cooking instructions on packaging before cooking

FSA

The Food Standards Agency (FSA), Food Standards Scotland (FSS) with Ipsos MORI have published a survey of consumer practices relating to coated frozen chicken products.

This survey identifies behaviours which could increase people’s risk to foodborne disease. It was commissioned as a result of a Salmonella incident linked to frozen chicken products such as nuggets, goujons, dippers, poppers and kievs. While these products may appear cooked on the outside, they often contain raw chicken and so they must be cooked thoroughly to help kill Salmonella bacteria.

Findings show that two thirds of adults aged 16-75 (67%) say they have recently cooked or eaten coated frozen chicken products at home. These products are particularly popular with younger adults, with 88% of those aged 16-24 having recently consumed them or cooked them at home. Participants were also more likely to have cooked or eaten these products if they have children aged 15 or under in their household (86%).

The survey also included questions on the storage and handling of these products pre and post-cooking:

  • Almost two thirds of those who cook these products (62%) say uncooked coated frozen chicken products at least sometimes come into contact with other surfaces such as worktops and plates
  • Over half of those who cook these products (58%) say they always wash their hands after handling coated frozen chicken products
  • Almost a quarter of consumers who personally cook products say they defrost them before cooking (23%), 62% say they do not. Among those who defrost products, half say they leave them at room temperature (53%)

Most participants who use an oven to cook coated frozen chicken products say they sometimes cook them together with other products, such as chips or vegetables (84%). Cooking these chicken products at a lower temperature or for a shorter time than advised may mean they are not thoroughly cooked before serving.

Narriman Looch, Head of Animal Feed and Foodborne Disease Control Branch said: ‘It’s important to understand that frozen chicken products often contain raw chicken, even though they may look pre-cooked on the outside. While additional measures have been put in place by food businesses to improve the safety of these products, consumers need to handle these products as they should other raw meat products. Cooking food at the right temperature and for the right amount of time will kill any Salmonella bacteria that may be in food. Therefore, we are urging consumers to follow cooking instructions for these products to protect themselves and their families.’

Food safety tips for frozen breaded chicken products:

  • Treat these products as raw chicken, ensuring they are steaming hot after cooking and surfaces they have touched are cleaned to avoid the spread of bacteria
  • Make sure the oven is up to temperature before cooking
  • Check the instructions on packaging and cook at the correct temperature and for the time stated
  • Wash your hands, utensils and clean surfaces after handling these products
  • If products require defrosting, follow the storage instructions on packaging and always defrost in the fridge

About this poll

The FSA and FSS commissioned an online survey via three waves of Ipsos MORI’s online omnibus of 5,599 adults (aged 16-75) living in the UK. Of these 3,740 had cooked or eaten coated frozen chicken products recently and went on to complete the full survey. The data was weighted to be representative of the UK adult population aged 16 – 75.

The full report is available in the research section of our website.

About the outbreak

FSA and FSS are continuing to work with Public Health England (PHE) and devolved public health authorities as well as our international food safety partners, via the United Nations’ World Health Organization, (WHO) and the Food and Agriculture Organization’s (FAO’s) International Food Safety Network (INFOSAN), to address the causes of the outbreak at source to prevent further cases of Salmonella Enteritidis.

Between January 2020 and May 2021 there have been 511 cases of Salmonellosis in the UK caused by two strains of Salmonella Enteritidis and linked to consumption of frozen, raw, breaded chicken products.

Authorities in Poland and UK retailers have taken action to reduce the risk from these products. Where non-compliant or unsafe food has been identified by the UK, action has been taken to protect consumers.

UK – UK patient count in Salmonella melon outbreak doubles.

Food Safety News

The number of people sick in the United Kingdom in an outbreak linked to melons has almost doubled.

The Food Standards Agency (FSA) and Public Health England (PHE) are investigating the incident with 99 people sick since April. It was previously known that 52 people were ill in the UK.

Those more than 70 and less than 9 years old are the age groups mostly affected. Investigations are focusing on the supply chain of galia, cantaloupe and honeydew melons from Honduras and Costa Rica.

FSA is working with trade associations and retail businesses to get information relevant to the outbreak. A quick rise in confirmed infections occurred in the week commencing May 24.

USA – Yogurt E. coli Outbreak: What is a Secondary Food Poisoning Infection?

Food Poisoning Bulletin

In the Pure Eire yogurt E. coli outbreak that has sickened at least 16 people in Washington and Arizona, some of the patients have contracted secondary food poisoning infections. This term may not be familiar to everyone. So what is this type of infection?

A secondary food poisoning infection occurs when someone gets sick from contact with another person, not by eating contaminated food or drinking contaminated water. Many pathogens can be spread person-to-person, by direct contact and common contact with fomites (surfaces), both through the fecal-oral route.

Research – “Aquaponics offers solutions to foodborne illness outbreaks”

Horti Daily

Soilless growing offers a viable alternative to growing crops in a low-risk environment for many microbial sources. Aquaponics, which is often greenhouse-grown, is an innovative way of growing fish and plants in rural or urban settings. For years, commercial aquaponic farms have obtained food safety certifications from Global GAP, USDA Harmonized GAP, Primus GFS, and the SWF Food Safety Program, in addition to being certified USDA organic (Aquaponic Association, 2019) and sold commercially across North America.

In an aquaponic system, the healthy microbes actually serve as biological control agents against pathogenic bacteria making their survival minimal (Fox, 2012). While aquaponics produce is not immune to all pathogenic contamination, it is one of the safest agriculture methods against pathogenic risk.

USA – Possible Salmonella Outbreak at Don Julio in North Branch, Minnesota

Food Poisoning Bulletin

A possible Salmonella outbreak at Don Julio restaurant in North Branch, Minnesota is being investigated by the Minnesota Department of Health, according to Information Officer Doug Schultz. He told Food Poisoning Bulletin that officials are investigating Salmonella cases that reported eating at that restaurant. Mr. Schultz added that there is not a risk to the general public from this outbreak.

Because the investigation is new and ongoing, there is no information about the number of patients, any hospitalizations, illness onset dates, the patient age range, or if the investigation is focusing on food or employees.

Japan – Central Japan City Hit by Apparent Mass Food Poisoning

Nippon.com

Toyama, June 17 (Jiji Press)–Numerous students and preschoolers in the central Japan city of Toyama have developed symptoms such as stomachache in what appears to be a case of mass food poisoning, the city government said Thursday.

Milk served with school lunches is believed to be responsible for the ailments of those affected, sources at a local public health center said. The city government conducted an on-site inspection of the company that produced the milk in question to determine the cause of the apparent food poisoning case.

Affected people are showing symptoms such as diarrhea, stomachache, vomiting and fever, but no one is in serious condition, city officials said.

USA – FDA Core Investigation Table – Shrimp Link in Salmonella Outbreak

FDA

*Shrimp: The information collected so far indicates that pre-cooked shrimp is the likely source of this outbreak, however it appears that the product lots linked to outbreak illnesses are past its shelf life and are no longer available for sale. The most recent illness occurred in late April 2021. FDA continues to investigate and if FDA’s outbreak investigation results in specific actionable steps for consumers to take to protect themselves, a public health advisory will be issued.

Norway – Norway links Salmonella outbreak to raw milk cheese

Food Safety News

Six people in Norway have fallen ill in recent months with the source of infection thought to be contaminated raw milk cheese from France.

The foodborne outbreak was suspected to be caused by Salmonella Dublin in chilled cheese made with unpasteurized milk.

The Norwegian Institute of Public Health (Folkehelseinstituttet) investigated the outbreak with the Norwegian Food Safety Authority (Mattilsynet) and Norwegian Veterinary Institute.

USA/Canada- Factors Potentially Contributing to the Contamination of Red Onions Implicated in the Summer 2020 Outbreak of Salmonella Newport

FDA

Executive Summary

Between June and October 2020, federal and state agencies investigated a Salmonella Newport foodborne illness outbreak associated with consumption of red onions from the Southern San Joaquin Valley and Imperial Valley in California. The outbreak, which caused 1,127 reported domestic illnesses and 515 reported Canadian cases, is the largest Salmonella outbreak in over a decade. This outbreak is also remarkable because the food vehicle, whole red onions, is a raw agricultural commodity that had not been previously associated with a foodborne illness outbreak.

The U.S. Food and Drug Administration (FDA), alongside state and federal partners, investigated the outbreak to identify potential contributing factors that may have led to red onion contamination with Salmonella Newport. While the Salmonella Newport outbreak strain (specific whole genome sequence [WGS]) was not identified in any of the nearly 2,000 subsamples tested, a total of 11 subsamples (10 water and 1 sediment) collected near one of the growing fields identified in the traceback were positive for Salmonella Newport, representing a total of three different genotypical strains (unique WGS patterns). Although a conclusive root cause could not be identified, several potential contributing factors to the 2020 red onion outbreak were identified, including a leading hypothesis that contaminated irrigation water used in a growing field in Holtville, California may have led to contamination of the onions.

While our investigation did not occur during any harvesting activities, visual observations of the implicated red onion growing fields suggested several plausible opportunities for contamination including irrigation water, sheep grazing on adjacent land, as well as signs of animal intrusion, such as scat and large flocks of birds which may spread contamination. Similarly, the investigation did not occur while packing activities were ongoing. However, visual observations and records review of packing house practices confirmed numerous opportunities for spread of foodborne pathogens such as Salmonella, including signs of animal and pest intrusion as well as food contact surfaces which had not been inspected, maintained, cleaned, or sanitized as frequently as necessary to protect against the contamination of produce. Thomson International Inc. cooperated with FDA throughout the investigation and is continuing to engage with FDA on the agency’s findings and recommendations.

Notably, Salmonella isolates from two sediment subsamples and two water subsamples collected during this investigation were found to be genetically related by WGS to clinical isolates from 2016 and 2018 foodborne illness outbreaks (Salmonella Muenchen and Salmonella Montevideo, respectively) associated with consumption of sprouts. This may be indicative of human pathogen persistence and distribution in this growing region (a concentrated area of seed for sprouting production), which could pose a risk of contamination for any produce commodity. FDA issued an assignment to follow-up at the associated firms. Sprouts are not a food vehicle of interest in the 2020 Salmonella Newport foodborne illness outbreak.

We urge growers to conduct risk assessments that include evaluation of hazards that may be associated with adjacent and nearby land uses—especially relating to the presence of livestock and wildlife and the potential for runoff into growing fields or water sources—and implement risk mitigation strategies where appropriate. FDA recognizes the interconnection between people, animals, plants, and their shared environment when it comes to public health outcomes, and we encourage collaboration among various groups in the broader agricultural community (e.g., produce growers, those managing animal operations, state and federal government agencies, and academia) to address this issue.

This document provides an overview of the traceback investigation, subsequent on-site investigation, and factors that potentially contributed to the contamination of red onions with Salmonella Newport.
