Fresh Red Meat Beef Supermarket
A Spanish study found 40% of supermarket meat samples contained multidrug-resistant E. coli strains, highlighting the need for regular assessments of antibiotic-resistant bacteria in meat products and emphasizing farm-to-fork interventions and proper food handling practices to reduce risks.
“Superbugs” present in chicken, turkey, beef and pork, Spanish study finds.
Multidrug-resistant E. coli were found in 40% of supermarket meat samples tested in a Spanish study. E. coli strains capable of causing severe infections in people were also highly prevalent, this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2023, Copenhagen, April 15-18) will hear.
Antibiotic resistance is reaching dangerously high levels around the world. Drug-resistant infections kill an estimated 700,000 people a year globally and, with the figure projected to rise to 10 million by 2050 if no action is taken, the World Health Organization (WHO) classes antibiotic resistance as one of the greatest public health threats facing humanity.
Multidrug-resistant bacteria can spread from animals to humans through the food chain but, due to commercial sensitivities, data on levels of antibiotic-resistant bugs in food is not made widely available.
To find out more, Dr Azucena Mora Gutiérrez and Dr Vanesa García Menéndez, of the University of Santiago de Compostela-Lugo, Lugo, Spain, together with colleagues from other research centres, designed a series of experiments to assess the levels of multidrug-resistant and extraintestinal pathogenic Enterobacteriaceae (Klebsiella pneumoniae, E. coli and other bacteria that can cause multidrug-resistant infections such as sepsis or urinary tract infections) in meat on sale in Spanish supermarkets.
They analysed 100 meat products (25 each of chicken, turkey, beef and pork) chosen at random from supermarkets in Oviedo during 2020.
The majority (73%) of the meat products contained levels of E. coli that were within food safety limits.
Despite this, almost half (49%) contained multidrug-resistant and/or potentially pathogenic E. coli. From those, 82 E. coli isolates were recovered and characterised. In addition, 12 K. pneumoniae isolates were recovered from 10 of the 100 meat products (7 chicken, 2 turkey and 1 pork).
Forty of the 100 meat products contained multidrug-resistant E. coli (56 of the 82 E. coli characterised). These included E. coli that produced extended-spectrum beta-lactamases (ESBLs), enzymes that confer resistance to most beta-lactam antibiotics, including penicillins, cephalosporins and the monobactam aztreonam.
The percentage of positive samples for the carriage of ESBL-producing E. coli per meat type was: 68% turkey, 56% chicken, 16% beef and 12% pork. This higher presence of ESBL-producing E. coli strains in poultry compared to other types of meat is likely due to differences in production and slaughter.
Twenty-seven per cent of the meat products contained potentially pathogenic extraintestinal E. coli (ExPEC). ExPEC possess genes that allow them to cause disease outside the gastrointestinal tract. ExPEC causes the vast majority of urinary tract infections (UTIs), is a leading cause of adult bacteraemia (sepsis) and is the second most common cause of neonatal meningitis.
Six per cent of the meat products contained uropathogenic (UPEC) E. coli – UPEC is part of the ExPEC group; these possess specific virulence traits that allow them to cause UTIs.
One per cent of the meat products contained E. coli harbouring the mcr-1 gene. This gene confers resistance to colistin, an antibiotic of last resort used to treat infections caused by bacteria resistant to all other antibiotics.
The study’s authors, who in a previous study reported high levels of bacteria that were potentially capable of causing severe human infections and/or multidrug resistant in chicken and turkey1, say that their latest research shows that consumers may also be exposed to these bacteria through beef and pork.
They are calling for regular assessment of levels of antibiotic-resistant bacteria, including ExPEC E. coli, in meat products.
Dr Mora adds: “Farm-to-fork interventions must be a priority to protect the consumer. For example, implementation of surveillance lab methods to allow further study of high-risk bacteria (in farm animals and meat) and their evolution due to the latest EU restriction programmes on antibiotic use in veterinary medicine.
“Strategies at farm level, such as vaccines, to reduce the presence of specific multidrug-resistant and pathogenic bacteria in food-producing animals, which would reduce the meat carriage and consumer risk.
“The consumer plays a key role in food safety through proper food handling. Advice to consumers includes not breaking the cold chain from the supermarket to home, cooking meat thoroughly, storing it properly in the refrigerator and disinfecting knives, chopping boards and other cooking utensils used to prepare raw meat appropriately to avoid cross-contamination. With these measures, eating meat becomes a pleasure and zero risk.”

Probably impervious to the grilling that people who like their meat on the bloody rare side subject it to.
The next mandates will be to feed only the woke and to ration the deplorables.
Just their plan to scare everyone from meat so when they ban meat to save climate change (it’s definitely in the plans). They won’t get very much pushback. I tell you they are really playing offense.
No gas stoves and they have a valid danger.
That’s why ya cook iy.
Napoleon is reputed to have said "Europe ends at the Pyrenees."
Better inject more mRNA into the meat, just to be sure.
so 40% of the folks who eat this stuff should be sick...they said it...not me...
I am sure that cooking the meat well kills most of the bad stuff.
But all this constant fear of things has ruined many an appetite. Now I think they are also grinding up beetles and grubworms and putting it in our food.
Yuck.
The carnivore diet.
Deceitful headline: 40% of SPANISH Supermarket meat.
Well there are bugs also inside of bugs as well. So no real stark contrast there either.
Tell all the women.
“So, why aren’t people who eat meat dropping like flies?”
Probably because if you properly cook meat, the e. coli bacteria dies before you eat it.
Oh, this is so SCARY!
Why couldn’t someone just invent a way to, uh, I don’t know, heat the meat up to a temperature that would kill the bacteria. Maybe it could be called COOKING. It’s just too bad that no one ever thought of that.
</sarc>
Maybe someone will invent FIRE soon!........................
Then maybe someone can invent barbecue soon!
this was in SPAIN
basically almost a 3rd world hell hole similar to Russia
Well, I’ve never been to Spain............................
