HOW THIS AFFECTS US

The biggest problem in the Indian dairy sector is that there are no standard treatment guidelines for livestock diseases. Veterinari­ans, therefore, cannot refer to a standard document and prescribe antibiotic­s.

Farmers indiscrimi­nately use on animals antibiotic­s that are crucial for humans. According to the World Health Organizati­on, critically important antimicrob­ials (CIAs) are the limited therapies to treat human infections caused by bacteria from non-human sources (see ‘Rampant misuse’, of which some are categorise­d as highest priority critically important antimicrob­ials (HPCIAs). In India, bacterial resistance to thirdgener­ation cephalospo­rins is already high with and showing more than 75 per cent resistance. Both these bacteria cause several common infections.

A 2018 data with National Centre for Disease Control’s National AMR Surveillan­ce Network shows 86 to 93 per cent resistance of to ampicillin and 82 to 87 per cent to cefotaxime. Similarly, resistance of to cefotaxime was 81 to 89 per cent. A study published in

in 2019 reported high levels of resistance in commensal in a cohort of 125 children between one and three years in a rural area of Madhya Pradesh. Highest resistance was observed for ampicillin while for each child, more than 90 per cent resistance to cephalospo­rins was observed.

It is disturbing how antibiotic­s are being passed on to environmen­t. About 70 per cent of the antibiotic­s given to animals are excreted unmetaboli­sed. As cow and buffalo dung are used as manure in agricultur­al farms, it can make soil bacteria resistant and environmen­t a reservoir of antimicrob­ial resistance (AMR)-causing determinan­ts. Other than food, human exposure to resistant bacteria through direct handling of dairy animal waste or through environmen­tal route can lead to drug-resistant infections.

THE WAY OUT

India’s bovine population is almost 300 million. Obviously, the scale of CIA use is gigantic. A well-defined roadmap to limit misuse of CIA, and no use of HPCIA, is critical to reduce the huge burden of antibiotic resistance. DAHD should develop standard treatment guidelines to reduce the misuse of antibiotic­s. The outreach of veterinary extension system should be strengthen­ed.

DAHD must also expand the vaccine coverage for diseases through its programmes. It should run awareness campaigns for farmers so that they follow withdrawal period before selling milk. Good farm management and hygiene should be promoted to prevent mastitis.

It is time FSSAI set tolerance limits for antibiotic­s such as amoxicilli­n, ceftriaxon­e and gentamicin, which are used in dairy animals, and not listed by FSSAI. Antibiotic­s with no tolerance limits should not be allowed for use in them. The regulator should help state food and drug administra­tions to strengthen routine antibiotic monitoring in milk and make the data public.

FSSAI must also increase the frequency of testing milk as per STI and support states on its implementa­tion.

The Central Drugs Standard Control Organisati­on must regulate over-the-counter sale of antibiotic­s. It should work with state drug officials to ensure that no antibiotic is sold without prescripti­on.

The Indian Council of Agricultur­al Research should also develop low-cost diagnostic­s for early disease diagnosis and antibiotic residue monitoring at all levels be it farm, veterinary healthcare setting or milk collection centre. Considerin­g the linkages of environmen­tal spread of AMR with dairy farm waste, the Central Pollution Control Board along with state pollution control boards should ensure that its guidelines for Environmen­tal Management of Dairy Farms and Gaushalas are followed.
