Multi-drug resistant bacteria caused by misuse of antibiotics in poultry
The study shows that the illegal disposal of the litter and waste from poultry farms in agricultural fields causes the spreading of multi-drug resistant bacteria.
CSE’s Pollution Monitoring Laboratory collected samples of litter and soil from 12 poultry farms located in four key poultry-producing states in north India (Uttar Pradesh, Haryana, Rajasthan and Punjab) and found a total of 217 isolates of three types of bacteria, E.coli, Klebsiella pneumoniae and Staphylococcus lentus respectively.
"These bacterias were extracted and tested for resistance to 16 antibiotics. Ten of these antibiotics have been declared Critically Important (CI) for humans by the World Health Organization (WHO)," the CSE statement reads.
The CSE researchers found that poultry farms used antibiotics and the manure collected from the farms was then spread across neighboring agricultural lands.
“Antibiotic misuse is common in the poultry sector. What makes the situation worse is the fact that the sector is also plagued with poor waste management. Therefore we first wanted to understand the extent of antibiotic resistance in the poultry environment, and then establish if the resistant bacteria is moving out of the poultry farms into the environment through waste disposal,” Chandra Bhushan, deputy director general, CSE, said.
"The measure responds to demands from the productive sector, which asked for more time to adapt t...
