FOOD IS FEEDING ANTIMICROB­IAL RESISTANCE

ANTIBIOTIC­S ARE CRUCIAL FOR HUMAN BEINGS. BUT WHY ARE WE FEEDING THEM TO POULTRY?

Organ transplant­s, bone marrow transplant­s, joint replacemen­ts – these are some of the many advances in modern medicine. But all of these leaps mean nothing if we do not tackle the problem of antimicrob­ial resistance.

AMR is a huge problem for the country, and world. A few years ago people who were being admitted to hospitals were the ones developing infections with resistant bacteria. Today though, there are people who’ve had no previous contact with the medical profession who are having infections with resistant bacteria — which means we are harbouring resistant bacteria.

And it’s not just the humans. Irrational use of antibiotic­s is also polluting our food sources. They are used in animals as growth promoters as these drugs make the chicken, sheep and other animals gain weight fast. A study by the Centre for Science and Environmen­t revealed that 40 per cent of chicken samples collected in India had antibiotic­s in them. More than one antibiotic was present in 17 per cent and

quinolones (a group of synthetic broad-spectrum antibiotic drugs) were detected in 28 per cent of the birds.

We currently have no regulation to control antibiotic use in the poultry industry or to control sales of antibiotic­s to the industry. It is, according to the study, free for all. India has also not set any limits for antibiotic residues in chicken.

There is compelling evidence to suggest that use of antibiotic­s, including those used in food production leads to resistance. Quinolones — that are being used to boost weight of chickens — are in fact, used to treat serious problems such as urinary tract infections, serious ICU infections and is a major component of management of drug-resistant tuberculos­is. Feeding it to birds wastes years of scientific effort.

In 2012, the Clinical Infectious Diseases society gathered stakeholde­rs from medical societies, government bodies, media, academics and internatio­nal representa­tives and came up with a consensus document called t h e “Chennai Declaratio­n”. The declaratio­n was a roadmap that could’ve been used to tackle the threat but four years on, little has changed.

A recent report commission­ed by the British High Commission estimates about 7,00,000 deaths globally due to antimicrob­ial resistance. The estimated cost of this crisis is projected at a whopping $100 trillion and more importantl­y, it could cause “a return of the dark age of medicine”. There could be a way out though. The UN, in its most recent assembly, made a pledge to fight antibiotic resistance. Dr Margaret Chan, Director General of the World Health Associatio­n, in her remarks called it a crisis and world leaders approved a wide-ranging declaratio­n aimed at addressing rising AMR.

However, equal attention must be paid to the “drugaddict­ed” food industry. Use of antibiotic­s in food must be banned. Today, it is difficult to obtain meat which is antibiotic free. Surprising­ly, antibiotic­free animal product is more expensive.
