Superbug bacteria found in people, animals and food across the European Union pose an "alarming" threat to public and animal health having evolved to resist widely used antibiotics, disease and safety experts warned on Wednesday.

A report on antimicrobial resistance in bacteria by the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC) said some 25,000 people die from such superbugs in the EU every year.

"Antimicrobial resistance is an alarming threat putting human and animal health in danger," said Vytenis Andriukaitis, the EU's health and food safety commissioner.
