A research team including scientists from the University of Santiago de Compostela and the Centro Tecnológico Agroalimentario de Lugo has analysed the presence of potentially pathogenic bacteria in 100 meat samples bought in supermarkets in Oviedo, Spain in 2020. The researchers found E. coli bacteria which produce enzymes that make the bacteria resistant to various types of antibiotics in more than half of the turkey (68 %) and chicken (56 %) samples, and less frequently in beef (16 %) and pork (12 %) samples. They also found E. coli bacteria that can cause urinary tract infections. The team presented these results at the European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), which is being held in Copenhagen, Denmark, until 18 April. 

Bacterial infections were the second leading cause of death in 2019. This is according to research published in The Lancet, which estimates that one in eight deaths that year was associated with bacterial pathogens. Five of these - S. aureus, E. coli, S. pneumoniae, K. pneumoniae and P. aeruginosa - accounted for more than half of all bacteria-related deaths.
