Research – Effect of Chlorine Dioxide Treatment on Human Pathogens on Iceberg Lettuce

MDPI

In the vegetable processing industry, the application of chlorine dioxide (ClO2) as a disinfectant solved in washing water to eliminate undesirable microorganisms harmful to consumers’ health and the shelf life of produce has been discussed for years. The disinfection efficacy depends on various factors, e.g., the location of microorganisms and the organic load of the washing water. The present study analyzed the sanitation efficacy of various concentrations of water-solved ClO2 (cClO2: 20 and 30 mg L−1) on Escherichia coli (1.1 × 104 cfu mL−1), Salmonella enterica (2.0 × 104 cfu mL−1) and Listeria monocytogenes (1.7 × 105 cfu mL−1) loads, located on the leaf surface of iceberg lettuce assigned for fresh-cut salads. In addition, it examined the potential of ClO2 to prevent the cross-contamination of these microbes in lettuce washing water containing a chemical oxygen demand (COD) content of 350 mg L−1 after practice-relevant washing times of 1 and 2 min. On iceberg leaves, washing with 30 mg L−1 ClO2 pronouncedly (1 log) reduced loads of E. coli and S. enterica, while it only insignificantly (<0.5 × log) diminished the loads of L. monocytogenes, irrespective of the ClO2 concentration used. Although the sanitation efficacy of ClO2 washing was only limited, the addition of ClO2 to the washing water avoided cross-contamination even at high organic loads. Thus, the application of ClO2 to the lettuce washing water can improve product quality and consumer safety. View Full-Text

UK – Update 12 March: The FSA is reiterating its advice on cooking frozen raw breaded chicken products following links to cases of Salmonella

FSA

The FSA is repeating advice to consumers following an updated recall linked to salmonella contamination.

SFC has issued an updated recall of chicken products because Salmonella Enteritidis (a food poisoning bug) has been found in some of these foods.

This update includes the original products identified in previous recalls as well as additional products.

Dr Colin Sullivan, Chief Operating Officer, FSA said:

‘The products are linked to two ongoing outbreaks of Salmonella Enteritidis (a food poisoning bug) in chicken from Poland.

‘The producer put additional controls in place to improve the safety of their products in November 2020. SFC has decided to withdraw and recall all of its chicken products produced before this date.

‘The FSA will be making additional checks to ensure the effectiveness of this withdrawal and recall.’

Products affected

The full list of products is available in the food alert.

Update on the wider Salmonella investigation

We are continuing to work with Food Standards Scotland (FSS), Public Health England (PHE), Public Health Scotland, Public Health Wales and the Public Health Agency in Northern Ireland as part of the ongoing investigation into two particular strains of Salmonella linked to frozen raw breaded chicken products from Poland.

We previously issued precautionary consumer advice in October 2020 and February 2021. Additional controls have been put in place by food businesses at production level. These changes to the production process are proving to be effective and we hope to see a further reduction in cases in the coming months as these products are removed from the food chain. While we continue these efforts, it is important that people carefully follow food hygiene advice.

Investigations are ongoing into identifying the source of the outbreaks at farm level in Poland. Should more products be identified actions to remove unsafe food will be taken.

Saheer Gharbia, Head of the Gastrointestinal Pathogens Unit of PHE’s National Infection Service, said:

‘While we appear to be past the peak of this outbreak, and case reporting rate has decreased in recent months, we are still detecting some cases through whole genome sequencing, so it is important that people carefully follow food hygiene advice. We continue to work closely with the Food Standards Agency to resolve the outbreak.

‘Salmonella generally causes a mild illness, although vulnerable groups like children under five years, the elderly, and those with weakened immune systems may experience more severe illness and may require hospitalisation. Symptoms of a Salmonella infection include diarrhoea, stomach cramps and sometimes vomiting and fever. Anyone who is concerned about symptoms should contact their GP or out of hours service in the first instance.’

Our advice to consumers

If consumers have bought any of the products in the updated recall, they can return them to the store where they were bought for a full refund.

We are encouraging consumers to always cook food at the right temperature and for the correct length of time to ensure any harmful bacteria are killed. Before serving these products, make sure they are steaming hot and cooked all the way through. When you cut into the thickest part of the meat, check that none of the meat is pink and that any juices run clear.

Anyone who is concerned about symptoms should contact their GP or out of hours service in the first instance.

Only the products listed in the recall notice are affected. There is no need to change your shopping habits for chicken products.

Research – In Vitro Screening of Chicken-Derived Lactobacillus Strains That Effectively Inhibit Salmonella Colonization and Adhesion

MDPI

nhibition of Salmonella by Lactobacillus has been a popular research topic for decades; however, the inhibition potential of chicken-derived Salmonella by chicken-derived Lactobacillus has not yet been studied. In this study, 89 strains of Lactobacillus from chicken intestines were isolated by national standard method, Gram staining, physiological, and biochemical experiments and molecular sequencing; The inhibition characteristics of 89 strains of chicken derived Lactobacillus against 10 strains Salmonella (S. Enteritidis SE05, SC31, SC21, SC72 SC74, SC79, SC83, SC87; S. bongori SE47; S. Typhimurium, SC85) were detected by agar inhibition zone, The results showed that the inhibition zone of 24 strains of chicken derived Lactobacillus was more than 10 mm, which indicated that the isolated chicken derived Lactobacillus could effectively inhibit the growth of Salmonella; The drug resistance and bile salt tolerance of these 24 strains were analyzed, The results showed that the standard strains LG and L76 were not resistant, and the other 22 Lactobacillus strains showed different degrees of resistance. The strains LAB24, LAB26, LAB53, LAB69, and L76 showed good tolerance at the concentration of 3 g/L bile salt; Caco-2 cell experiment and flow cytometry were used to analyze the inhibitory effect of chicken derived Lactobacillus on the adhesion of Salmonella to Caco-2 cells, The results showed that 16 probiotics could effectively inhibit the adhesion of Salmonella to Caco-2 cells. Twelve probiotics were identified by molecular biology. The results showed that L76 was Enterococcus faecalis, and the other 11 strains were Lactobacillus. View Full-Text

Research – Behavioral Ethics and the Incidence of Foodborne Illness Outbreaks

Springer

Cognitive biases play an important role in creating and perpetuating problems that lead to foodborne illness outbreaks. By using insights from behavioural ethics, we argue that sometimes people engage in unethical behaviour that increases the likelihood of foodborne illness outbreaks without necessarily intending to or being consciously aware of it. We demonstrate these insights in an analysis of the 2011 Listeriosis outbreak in the U.S. from the consumption of contaminated cantaloupes. We then provide policy implications that can improve our understanding of other kinds of disease outbreaks and epidemics.

Denmark – Three suspected cases of botulism in Denmark

SSI

kswfoodworld

An outbreak of disease with suspected botulism has occurred among the participants in a private company in the region of Southern Denmark. The Danish Veterinary and Food Administration, Fødevareinstituttet DTU and Statens Serum Institut are working to identify the source of the infection, which is presumed to be limited to a single company.

Following a private party held on Friday, March 5, 2021, three adults have been hospitalized on suspicion of having botulism.

They are being treated with botulism antitoxin and are improving. The Statens Serum Institut (SSI) is now examining samples from the patients to find out if there was actually botulism.

SSI is also in the process of analyzing the ingredients and leftovers of the food that has been eaten by that company. No other patients with botulism are known outside the company that has been affected.

Kenya – Tough Terms As Kenya Lifts Tanzania, Uganda Maize Imports Ban -Aflatoxin

All Africa

All stakeholders dealing in maize imports would be required to be registered, the consignments coming in must be accompanied with certificate of conformity on aflatoxin levels and that traders have to issue details of their warehouses and the certificate of conformity should indicate that the aflatoxin levels complies with the maximum required levels of 10 parts per billion, the Ministry of Agriculture said. This comes a week after Kenya banned the importation of maize from two neighbouring countries, Tanzania and Uganda, after studies revealed higher than normal levels of mycotoxins. In a letter to the neighbours, the Kenya Agriculture and Food authority said they were “conducting surveillance on the safety of food imports into Kenya”. Mycotoxins are naturally occurring toxins produced by certain fungi and can be found in food. It grows on a variety of different crops and foodstuffs including cereals, nuts, spices, dried fruits, apples and coffee beans, often under warm and humid conditions.

Sweden – Norovirus in Sweden linked to shrimp from Estonia

Food Safety News

Food Borne Illness - Norovirus -CDC Photo

Outbreaks of norovirus in Sweden linked to shrimp from Estonia may have affected about 100 people.

Reports from local authorities have not been fully compiled yet but based on preliminary information officials believe more than 100 people have fallen sick.

It is mostly local outbreaks at workplaces where people have eaten shrimp sandwiches or a popular product in Scandinavia called “smörgåstårta.” This food, also called a sandwich cake, looks like a cake but instead of sponge uses bread and often includes cheese, vegetables, cold meats and fish.

Peeled shrimps in brine from the implicated batch were mostly distributed within one region which was named by local media as Varnamo in Jönköping County in southern Sweden.

USA – Almost 100 sick as Arby’s restaurant closes for second time – Norovirus

Food Safety News

norovirus-1080x655

An Arby’s restaurant has closed for the second time in less than a month because of an outbreak of foodborne illnesses among its customers. Health officials say the pathogen involved is norovirus, which is notoriously hard to eradicate. 

More than 90 people have reported becoming ill after eating at the Springfield, IL, Arby’s location. The first illnesses were reported in mid-February, spurring the first temporary closure of the restaurant for cleaning.

An employee of the Sangamon County Department of Public Health confirmed that the restaurant on Dirksen Parkway in Springfield has temporarily closed for a second time. The department recommended deep cleaning and employee training. Officials made similar recommendations for the first closure in late February.

New Zealand – New Zealand Food Safety warns consumers not to eat raw mussels – Vibrio parahaemolyticus

MPI

New Zealand Food Safety is warning consumers to thoroughly cook mussels before eating following 2 people reportedly becoming sick from Vibrio parahaemolyticus in the Nelson-Tasman region.

Paul Dansted, director of food regulation at New Zealand Food Safety said, “Vibrio parahaemolyticus is bacteria in mussels that may cause food poisoning if they’re undercooked or eaten raw. People with low immunity, pregnant, or elderly should avoid eating raw or undercooked shellfish as the illness can be more severe.

“While the cause has not been established both people who became ill have reported eating mussels and as a precaution we are reminding consumers to cook mussels thoroughly before consumption.”

New Zealand Food Safety advises consumers to follow simple food safety guidance to avoid contracting Vibrio parahaemolyticus by following 3 simple rules: Clean, Cook, Chill.

Clean

Always wash your hands and kitchen utensils after handling raw seafood, and before using other utensils or handling other foods. This will prevent the bacteria from spreading in your kitchen.

Cook

Cook mussels until steaming hot. Don’t eat shellfish raw or lightly cooked as this won’t get rid of bacteria such as Vibrio parahaemolyticus. One good way to know mussels are fully cooked is that their shells pop open when boiled or steamed, and the mussel inside is firm to the touch.

Chill

Refrigerate shellfish as soon as possible after harvesting or purchasing from the supermarket. You can use a chilly bin filled with ice blocks to transport live shellfish in your car. Once you get home, you should store mussels in a bowl covered with a wet towel in the bottom shelf in your refrigerator.

“New Zealand Food Safety is currently working with the Marlborough/Nelson District Health Board, Marlborough District Council and Institute of Environmental Science and Research to ensure appropriate public health measures are taken,” said Mr Dansted.

What to do if you get sick

If you get sick after eating shellfish, phone Healthline for advice on 0800 61 11 16 or seek medical attention immediately. If possible, store and refrigerate any leftover shellfish for testing.

Vibrio parahaemolyticus symptoms may include: watery or bloody diarrhoea, abdominal cramps, nausea, vomiting, fever, and/or headache.

Note, the event organisers of the Havelock Mussel Festival on Saturday, 13 March have been contacted and are aware of the issue. Organisers will only serve fully cooked mussels at the event.
