Conservative MP Zac Goldsmith has called on supermarkets to curb the use of antibiotic in farming and food.
A recent study by the University of Cambridge revealed the presence of three highly important antibiotics across British origin pig and chicken meat in major supermarkets.
This discovery along with the October revelation of MRSA on UK pork, provides evidence of the overuse of antibiotics in intensive farming, according to Mr Goldsmith.
Mr Goldsmith has called on supermarkets to dramatically curb those classified as 'critically important' to humans by the World Heath Organisation.
"The recent revelation of multi-drug resistant bacteria in supermarket meat lends a new urgency to the need for supermarkets to tackle antibiotic overuse in their supply chains," said Mr Goldsmith.
"The routine preventative mass medication of animals should have no place in the supply chain of any responsible retailer.
"I have no doubt that UK supermarkets will rise to this challenge, and will strive to ensure that the destruction of our antibiotics does not happen on their watch."
'Supermarkets must commit'
Following the findings, the Food Standards Agency pledged to work with supermarkets to cut farm antibiotic use.
In addition, Waitrose updated their antibiotic-use policy in September to state that they are working towards significant year on year reductions.
But it is still permitted by most UK supermarkets.
Emma Rose from the Alliance to Save our Antibiotics said: "In September this year, thousands of UK citizens called for supermarkets to ban the routine mass medication of groups of livestock and to curb use of the 'critically important' drugs.
"Now, MPs are expressing their concern around the lack of adequate supply chain policies on antibiotic-use.
"Supermarkets must commit to tackling this issue, and support farmers to reduce and improve veterinary prescribing."
