USA – Enoki Mushrooms are the Most Recalled Food of 2022

Food Poisoning Bulletin

With one month to go before the end of the year, there have already been 11 Listeria recalls for enoki mushrooms, making them the food most recalled for bacterial contamination in 2022. It wasn’t a close contest. Any commodity vying for the distant second-place finish  -cheese, leafy greens, ground beef, has had fewer than half as many recalls so far this year.

And there’s a decent chance that, before the year’s end, there will be a 12th enoki mushroom recall. That’s because no recall has been issued in connection with an ongoing enoki mushroom Listeria outbreak.

Ireland – E. coli found in 1 in 20 private water supplies, says EPA.

EPA

Key Findings for 2021

➤Compliance with drinking water standards in private supplies hasn’t improved in recent years. One in 20 supplies failed to meet the standard, compared to 1 in 200 for public water supplies.

➤Local authorities are not monitoring over a quarter of small private supplies for E. coli – and there may be many more supplies which need to be registered with the local authority.

➤Despite these shortcomings, over 60% of government funding available for infrastructural improvements went unused by water suppliers.

➤The timely completion of the Government review of rural water services will provide direction and support to water suppliers to address risks to public health.

Research – Annual report on the food safety situation in Catalonia, 2020

ACSA

Based on the available data collected in the 2020 Report, we can conclude that the situation in this matter remains, in general terms, stable. However, the COVID-19 pandemic has generated significant deviations in some parameters such as, for example, food poisoning outbreaks that have deviated widely from the usual data of the historical series of the last twenty years with a drop of more than 50% compared to previous years.

India – 123 people affected by food poisoning after eating prasad in a religious program

Irshad Gul

In Padra of Vadodara district on Sunday evening, a large number of people present at a religious function were affected by food poisoning after consuming prasad. All 123 people, including children, were immediately admitted to the government hospital in Padra. Some people whose condition was known to be critical were shifted to private hospitals. It is known that the condition of all the admitted patients is improving

USA – Holiday Reminder: Raw Dough Can Contain Dangerous Pathogens

Food Poisoning Bulletin

It’s time for the annual holiday reminder: raw dough can contain dangerous pathogens. While most people know that eating raw eggs is risky, fewer know that uncooked flour is also a potential hazard.

The FDA has been warning consumers about the potential dangers of raw eggs for decades. Eggs can carry Salmonella bacteria not only on the shell, but inside the egg itself. Hens can carry the pathogen in their ovaries, so the eggs are then contaminated from the inside out. Always handle raw eggs as if they are contaminated. Cook them thoroughly, and avoid recipes that use raw eggs. Eggs that are pasteurized are safe to eat raw, as long as you follow expiration dates.

There have been outbreaks linked to raw, or uncooked flour, in the past few years. Flour is a raw agricultural product and can be contaminated just like cantaloupe and romaine lettuce.

So when you are baking this holiday season, there are some things to remember. Follow package directions on baking mixes and four containers. Keep flour and eggs away from foods that are eaten uncooked. Refrigerate cookie and pastry dough if you aren’t going to be baking immediately.

Never eat or taste raw dough or cake batter unless it is made with pasteurized eggs and commercial heat-treated flour. Do not make play dough out of raw flour. Don’t use cake mixes to make milkshakes. While there are instructions for heat-treating your flour at home, the FDA doesn’t recommend it, since these treatments may not kill all pathogens. There are several brands of commercial heat-treated flour you can buy. Don’t use raw cookie dough in ice cream.

Sweden provides detail on outbreaks in 2021

Food Safety News

Sweden has noted an increase in foodborne outbreaks and illnesses in 2021 but levels were still below pre-COVID-19 pandemic figures.

The number of outbreaks reported to the Swedish Food Agency (Livsmedelsverket) in 2020 and 2021 was affected by measures taken during the pandemic.

There were 251 reports of suspected or confirmed food poisoning outbreaks with 1,467 illnesses. Both the number of reports and the number of cases increased compared to 160 outbreaks and 1,314 cases in 2020 but are still lower than the historical average.

When several Coronavirus-related restrictions were lifted in the autumn of 2021, the number of cases increased. Sixteen major outbreaks occurred during this season.

Eleven people have been hospitalized in seven outbreaks and one person died during a Campylobacter epidemic which infected eight people.

The Administration for Safe Food, Veterinary Medicine and Plant Protection (UVHVVR) together with the National Institute of Public Health (NIJZ) is investigating the increased number of reported cases of salmonella infections in Slovenia, which are being handled by the regional units of the NIJZ Ravne na Koroškem, Murska Sobota, Celje and Ljubljana. On the basis of the information received from the epidemiological service of the NIJZ, the UVHVVR started inquiries and inspections.

The epidemiological investigation showed that there were mostly unrelated cases, but the probability of consuming the same food stood out.

Research -Application of a novel phage ZPAH7 for controlling multidrug-resistant Aeromonas hydrophila on lettuce and reducing biofilms

Science Direct

Abstract

Aeromonas hydrophila is an important pathogenic bacterium that causes foodborne illness worldwide. In this study, virulent phages from the sediment of a fish farm were propagated and isolated on a multidrug-resistant strain of A. hydrophila, ZYAH75. One phage, designated as ZPAH7, featured a unique turbid halo around a clear plaque on the bacterial lawn (indicative of potential depolymerase activity), and was selected for further analysis. ZPAH7 was classified as podophage by morphological and genomic methods. Further comparisons of genome nucleotide similarity, ratios of homologous proteins and phylogenetic relatedness among the terminase large subunit and major capsid proteins of similar phage deposited in GENBANK, led us to propose a new genus, ZPAH7virus, in the Autographivirinae subfamily of Podoviridae. ZPAH7 had an adsorption rate of 79% in 5 min, an eclipse period of 15 min, a latent period of 25 min, and a burst size of 148 ± 9 PFU/cell. Antimicrobial application experiments showed that ZPAH7 lead to significantly reduction on A. hydrophila on lettuce. Additionally, ZPAH7 was able to inhibit biofilm formation, as well as degrade and kill bacteria in established biofilms. Furthermore, lytic activity of ZPAH7 remained stable across a wide range of temperatures and pH measurements. These results suggest ZPAH7 could be used as a potential biological control agent against A. hydrophila on food and/or biofilms on food contact surfaces.

Research – Dynamic Changes of Bacterial Communities and Microbial Association Networks in Ready-to-Eat Chicken Meat during Storage

MDPI

Ready-to-eat (RTE) chicken is a popular food in China, but its lack of food safety due to bacterial contamination remains a concern, and the dynamic changes of microbial association networks during storage are not fully understood. This study investigated the impact of storage time and temperature on bacterial compositions and microbial association networks in RTE chicken using 16S rDNA high-throughput sequencing. The results show that the predominant phyla present in all samples were Proteobacteria and Firmicutes, and the most abundant genera were WeissellaPseudomonas and Proteus. Increased storage time and temperature decreased the richness and diversity of the microorganisms of the bacterial communities. Higher storage temperatures impacted the bacterial community composition more significantly. Microbial interaction analyses showed 22 positive and 6 negative interactions at 4 °C, 30 positive and 12 negative interactions at 8 °C and 44 positive and 45 negative interactions at 22 °C, indicating an increase in the complexity of interaction networks with an increase in the storage temperature. Enterobacter dominated the interactions during storage at 4 and 22 °C, and Pseudomonas did so at 22 °C. Moreover, interactions between pathogenic and/or spoilage bacteria, such as those between Pseudomonas fragi and Weissella viridescensEnterobacter unclassified and Proteus unclassified, or those between Enterobacteriaceae unclassified and W.viridescens, were observed. This study provides insight into the process involved in RTE meat spoilage and can aid in improving the quality and safety of RTE meat products to reduce outbreaks of foodborne illness. View Full-Text
