Research – UAE: Counts of E.coli in vegetables from retailers in Abu Dhabi and Dubai

Horti Daily

A new study by Ihab Habib, Rami H Al-Rifai, Mohamed-Yousif Ibrahim Mohamed, Akela Ghazawi, Afra Abdalla, Glindya Lakshmi, Neveen Agamy and Mushtaq Khan investigates the counts, antimicrobial resistance profile, and genome-based characterization of Escherichia coli in 11 different types of fresh salad vegetable products (n = 400) sampled from retailers in Abu Dhabi and Dubai in the United Arab Emirates.

E. coli was detected in 30% of the tested fresh salad vegetable items, with 26.5% of the samples having an unsatisfactory level (≥100 CFU/g) of E. coli, notably arugula and spinach. The study also assessed the effect of the variability in sample conditions on E. coli counts and found, based on negative binominal regression analysis, that samples from local produce had a significantly higher (p-value < 0.001) E. coli count than imported samples.

The analysis also indicated that fresh salad vegetables from the soil-less farming system (e.g., hydroponic and aeroponic) had significantly (p-value < 0.001) fewer E. coli than those from traditional produce farming. The study also examined the antimicrobial resistance in E. coli (n = 145) recovered from fresh salad vegetables and found that isolates exhibited the highest phenotypic resistance toward ampicillin (20.68%), tetracycline (20%), and trimethoprim-sulfamethoxazole (10.35%).

A total of 20 (13.79%) of the 145 E. coli isolates exhibited a multidrug-resistant phenotype, all from locally sourced leafy salad vegetables. The study further characterized 18 of the 20 multidrug-resistant E. coli isolates using whole-genome sequencing and found that the isolates had varying numbers of virulence-related genes, ranging from 8 to 25 per isolate. The frequently observed genes likely involved in extra-intestinal infection were CsgA, FimH, iss, and afaA. The β-lactamases gene blaCTX-M-15 was prevalent in 50% (9/18) of the E. coli isolates identified from leafy salad vegetable samples.

The study highlights the potential risk of foodborne illness and the likely spread of antimicrobial resistance and resistance genes associated with consuming leafy salad vegetables. It emphasizes the importance of proper food safety practices, including appropriate storage and handling of fresh produce.

UK -UKHSA issue warning as infections rise in East of England

EDP 24

Families visiting farms and petting zoos this summer are being urged to protect themselves following a rise in infections.

The UK Health Security Agency (UKHSA) has issued a warning about gastrointestinal infections such as salmonella, cryptosporidium and e.coli.

They can all be passed from farm animals to humans, causing illness.

There have already been 92 cases of cryptosporidium in the east of England so far this year, 14 more than in all of 2022.

So the UKHSA is urging anyone visiting a farm to remember the importance of thoroughly and frequently washing hands to avoid getting the bugs, which can make you seriously ill.

Quebec – Notice not to consume Alfredo Rosso sauce prepared and sold by the company Del Monaco – E.coli


QUEBEC CITY ,  May 29, 2023 /CNW/ – The Ministry of Agriculture, Fisheries and Food (MAPAQ), in collaboration with the Food Inspection Division of the City of Montreal and the company Del Monaco , located at 2968, boulevard Saint-Charles , in Montreal ( Kirkland ), warns the public not to consume the product indicated in the table below, because this food is likely to contain the bacterium  E. coli .

RASFF Alert – E.coli – Clams

USA – Missoula County Health Officials issue warning about raw milk following possible Coxiella burnetii exposure

Food Poison Journal

Following potential exposure to bacteria from unpasteurized milk sold at a farmers’ market in Missoula County, the Missoula City-County Health Department is warning residents of the dangers of consuming unpasteurized, or “raw,” milk.

Milk that was recently sold at a local farmers market came from a herd where two cows tested positive for Coxiella burnetii, which is the bacteria that causes Q fever. While one of those cows had not yet produced milk, the other produced about 10% of the farmer’s yield.

“We don’t know if the cow was shedding the bacteria at the time it was milked, or if that cow’s milk was sold at the farmers market,” said Environmental Health Director Shannon Therriault. “So, we can’t say for sure whether anyone was exposed. However, what we do know is that unpasteurized milk can contain harmful bacteria that can make you and your loved ones sick.”

Unpasteurized milk products have been linked to outbreaks of E. coli, campylobacter, salmonella, brucella, listeria and cryptosporidium. In the case of Q fever, symptoms can take two or three weeks to present following exposure. According to the Centers for Disease Control and Prevention, symptoms of Q fever include fever, chills, fatigue, headache, muscle aches, nausea, vomiting, diarrhea, chest pain, stomach pain, weight loss and a non-productive cough.

New Research Links Foodborne E. Coli Infections to “Hundreds of Thousands” of UTIs in U.S.

Food Safety Magazine

A new study suggests that Escherichia coli infection from contaminated meat products may be responsible for hundreds of thousands of urinary tract infections in the U.S. each year.

A team of scientists led by George Washington University (GWU) Milken Institute School of Public Health researchers have developed a new genomic approach for tracking the origins of E. coli infections. Using this method, the team estimated that between 480,000 and 640,000 UTIs in the United States each year may be caused by foodborne E. coli strains.

According to GWU, E. coli is the most common cause of UTIs, causing upwards of 85 percent of cases each year. Women are at greater risk of developing UTIs, which can range from simple bladder infections to life-threatening bloodstream infections. At present, only specific types of diarrhea-causing E. coli, such as E. coli O157:H7, are rigorously monitored by the U.S. Food and Drug Administration (FDA), but the new findings from GWU suggest that other strains may also pose serious health risks.

In the study, researchers collected raw chicken, turkey, and pork from major grocery store chains in Flagstaff, Arizona, and isolated E. coli from the meat samples. Simultaneously, researchers collected urine and blood E. coli isolates from patients hospitalized at the Flagstaff Medical Center for UTIs.

Research – Norway records rise in outbreaks in 2022

Food Safety News

The number of outbreaks and people sick in them in 2022 went up from the year before, based on new data from Norway.

A total of 34 foodborne outbreaks were reported in 2022, which is up from 23 and 25 outbreaks in 2020 and 2021 but lower than the 46 outbreaks in 2019.

Overall, 628 people were sick this past year with the largest incident affecting 100 people, according to a report published by the Norwegian Institute of Public Health (FHI). In the 25 outbreaks in 2021, 327 patients were recorded.

Eight norovirus outbreaks sickened 135 people in 2022. Five outbreaks with 148 cases were caused by Salmonella. Cryptosporidium and Yersinia were behind three each with 14 and 51 patients, respectively.

Ten people were sick in two Listeria outbreaks. One Campylobacter outbreak had six patients and one E. coli event affected seven people. The agent was unknown for 11 outbreaks with 257 cases.

Most foodborne outbreaks were reported in connection with restaurants, cafes and other catering establishments.
