Salmonella outbreak ongoing with 130 sick; Listeria incident over in UK

Food Safety News

Investigations into a Salmonella outbreak are ongoing but a Listeria outbreak has ended, according to the Food Standards Agency (FSA).

More than 130 people are sick with Salmonella Mbandaka after eating chicken products from Ukraine. Four patients were admitted to hospitals and one person died.

In response to repeated non-compliance with partly cooked chicken products from Ukraine, a system of Intensified Official Controls (IOC) was started in April. This included a requirement that the next 10 imported consignments from the implicated establishment would be subject to extra inspections.

Because of continued breaches of food safety requirements, this was escalated to Imposed Checks in May. These physical, documentary and testing inspections will remain in place until a minimum of 30 consecutive favorable results are achieved.

The UK importer has stopped receipt of the steam-cooked chicken product until the issue is resolved and is testing all their uncooked product on arrival into the UK for Salmonella. An investigation by Ukrainian authorities has resulted in risk management measures being taken at the facilities of the manufacturer.

In late 2022, the European Centre for Disease Prevention and Control (ECDC) reported that Finland had 89 cases while a few patients also lived in the Czech Republic, Estonia, France, Germany, Ireland, the Netherlands, and Israel.

Research – Does Vegan Cheese Pose a Food Safety Risk?

Posted on June 30, 2023 by | Leave a comment

Food Poisoning Bulletin

Recently, the Centers for Disease Control and Prevention (CDC) published an analysis of a Salmonella outbreak linked to vegan cheese made from cashews. The 2021 outbreak linked to Jule’s cashew brie marked the second time since 2014 that illnesses in multiple states were linked to cashew cheese.

Does vegan cheese pose a food safety risk? If it’s made from nuts, it might.

Cashews and Kill Steps

The CDC’s 2021 report on the Jule’s brie Salmonella outbreak states that whole genome sequencing tests on the Salmonella strain cultured from patients produced the same genetic “fingerprint,” meaning the patients were exposed to the same source of contaminated food. Investigators found this outbreak strain in samples of Jule’s cheese, in the facility where it was made, and in the specific lot of raw cashews used to make the cheese.

The CDC’s recent analysis of the outbreak states that U.S. Food and Drug Administration (FDA) investigators identified cashews as the ingredient that was the likely source of contamination and noted that no lethality treatment, or “kill step” such as pasteurization or irradiation was performed before cashew processing.

Similarly, a kill step was also omitted in the manufacture of The Cultured Kitchen cashew cheese linked to the 2014 Salmonella outbreak. Tests performed during that investigation revealed the presence of the outbreak strain in samples of the cheese collected from a patient’s home and in a batch of fermenting, raw, cashews collected from the facility where the product was made.

Wales – Second childcare setting identified in STEC E.coli probe

Posted on June 29, 2023 by | Leave a comment

Wales Online

A second childcare setting has been identified in an investigation into an E.coli case in Wales. Public Health Wales confirmed that it was investigating two cases of E.coli in children who attend the nursery at Ysgol Pen Barras in Ruthin on Saturday.

However, PHW has since re-classified one of these cases as “probable”, rather than confirmed. One child who attends the school has got a confirmed diagnosis of E.coli.

While there is currently no evidence to suggest the case has been transmitted or acquired from the school, children in the nursery and reception classes at the school were asked not to attend on Monday and Tuesday and were also asked to provide stool samples.

Korea – Wash hands after touching eggs: Food agency warns of salmonella outbreak

Posted on June 29, 2023 by | Leave a comment

Korean Herald

Food safety authorities on Wednesday warned people to wash hands promptly after handling or cooking raw eggs, citing food poisoning risks from Salmonella, a harmful bacterium found in poultry and mammal intestines.

There have been numerous cases of food poisoning caused by cross-contamination, where individuals handle eggs and then fail to wash their hands before cooking food or touching other cooking utensils, according to the Ministry of Food and Drug Safety.

UK retailers share Campylobacter in chicken results

Posted on June 28, 2023 by | Leave a comment

Food Safety News

Supermarkets in the United Kingdom have reported their Campylobacter in chicken results for late 2022.

The Food Standards Agency (FSA) maximum target level is up to 7 percent of birds with more than 1,000 colony-forming units per gram (CFU/g) of Campylobacter.

Data from the retailers covers October to December 2022 on high findings of Campylobacter in fresh, shop-bought, UK-produced chickens.

Results at Waitrose, Morrisons and Lidl went up while Marks and Spencer, Aldi, Asda, and Sainsbury’s recorded lower levels of contamination than the previous quarter. Figures for Co-op stayed the same.

Campylobacter is the most common cause of bacterial food poisoning in the UK and the dose needed to make people sick can be as low as a few hundred cells.

Tesco has stopped publishing data as it has changed the way it monitors the pathogen in chicken so findings are not comparable with other retailers.

Catalonia – Cook and preserve egg foods safely

Posted on June 28, 2023 by | Leave a comment

ACSA

Foods made with eggs or egg products appear in Catalonia as the leading cause of food poisoning (diseases transmitted by food). The egg, by its nature, is a food sensitive to contamination and bacterial multiplication.
Foods made with eggs such as tortillas, creams, flans, quiches, etc.:
  • They must be cooked at a temperature that reaches 75°C in the center of the product. You have to curdle the tortillas well. Cooking is the only way to kill dangerous germs, including salmonella. Insufficient cooking does not guarantee the elimination of germs.
  • They should be consumed immediately or kept in the refrigerator.
  • It cannot be kept at room temperature for more than two hours.
Both mayonnaise and other sauces made with raw eggs do not receive any heat treatment that eliminates possible germs, therefore, in the preparation and preparation of these foods it is necessary to strictly respect the following hygiene rules:
  • Just the right amount of sauce should be prepared to be consumed in a single meal. The sauces should not be kept for later days.
  • If we add a few drops of vinegar or lemon, it will improve its conservation.
  • They must be kept in the refrigerator until they are consumed or used in other dishes that we must also refrigerate.
Restaurants, cafeterias, bars, seasonal establishments, central kitchens and collective dining rooms and any other establishment that serves meals may only use pasteurized egg products for the preparation of mayonnaise or other sauces that contain raw eggs.

Research – Strategies to Reduce Clostridium botulinum Risk in Fresh-Cut Produce

Posted on June 27, 2023 by | 2 comments

food safety.com

The risks associated with Clostridium botulinum and low-acid canned foods, meats, seafood, and temperature-abused foods are generally well-established. However, there has been increasing consideration toward C. botulinum and its potential as a pathogen of concern for fresh-cut vegetables, fruits, and mushrooms.

For an industry segment beleaguered by recent outbreaks of Shiga toxin-producing Escherichia coli, Salmonella enterica, and Listeria monocytogenes, consideration of a bacterial pathogen with vastly different growth characteristics—one that is less traditionally associated with fresh produce—may seem burdensome. However, recent incidences of C. botulinum in packaged mushrooms,1 increased characterization of the growth conditions required by nonproteolytic C. botulinum, widespread industry adoption of modified atmosphere packaging (MAP), and even increasing fuel costs may necessitate a second look at this pathogen’s association with fresh produce.

Research- When Does Milk Spoil? The Use of Rejection Threshold Methodology to Investigate the Influence of Total Microbial Numbers on the Acceptability of Fresh Chilled Pasteurised Milk

Posted on June 25, 2023 by | Leave a comment

MDPI

Abstract

The consumer rejection threshold (RjT) method was applied to determine the total microbial numbers (TMNs) where consumers find that the quality of whole fresh chilled pasteurised milk (WFCPM) and skim milk (Trim) stored at 4.5 ± 0.5 °C is no longer acceptable. Food spoilage progression was supported by measurements of VOCs and the terms consumers used to describe the ageing fresh chilled pasteurised milk (FCPM). RjTs for TMN of 7.43 and 7.34 log10 CFU.mL−1 for WFCPM and Trim, respectively were derived using Hill’s equation from a series of paired preference tests comparing fresh and aged milks (3–26 days) assessed by consumers (WFCPM, n = 55; Trim, n = 52). A poor relationship between storage time and TMN was found, owing mainly to batch-to-batch and within-batch variation in the milk’s post-pasteurization contamination (PPC) levels. At the RjT, there was a significant change in the signal intensities for a number of spoilage-related VOCs that occurred in the FCPM headspace (p ≤ 0.05), which were measured using proton transfer reaction–mass spectrometry (PTR-MS), including m/z 33, 45, 47, 61, 63, 69, 71, 87, and 89, tentatively identified as methanol; acetaldehyde; ethanol; acetate (acetic acid and acetate esters); dimethyl sulphide (DMS); isoprene, furan, and aldehydes; 2-butanone; and pentanal and butyrates (butyric acid and butyrate esters), respectively. Consumers described the milks at TMN greater than the RjTs using terms like off, expired, sour, spoilt or rancid. This multidisciplinary study has provided data on the importance of PPC and subsequent increases in TMN on VOCs associated with FCPM and consumer’s preferences and highlighted the value of measuring a range of variables when investigating consumer’s perception of food quality and shelf-life.
