What is the reason for the sharp rise in death according to EU?

The European Union warned Thursday of a sharp rise in deaths across the EU 27-nation bloc due to bacteria becoming resistant to antibiotics.
    With some 25,000 Europeans dying each year from infections caused by drug-resistant bacteria, European health commissioner John Dalli said "we need to take swift and determined action if we do not want to lose antimicrobial medicines" for humans and animals.
    A five-year EU plan to contain the risk of antimicrobial resistance, also known as AMR, calls for research in areas affecting both humans and animals, as resistant bacteria can be transferred from animals to humans in the food chain.
