Antibiotics in food need more scrutiny

Professor Peter Collignon, an expert in infectious diseases and microbiology from the Australian National University, believes the first step would be to ban the use of third-generation cephalosporins in animals, as the US has done.

Writing in The Lancet, he warned of potentially untreatable salmonella infections — such as the Kentucky serotype — with strains becoming increasingly resistant to fluoroquinolones, third-generation cephalosporins and carbapenems.

Fluoroquinolones are banned in animals used for food production in Australia
