Colistin - A new reason to be worried

What is Colistin?

Colistin is extensively used in veterinary practices as a growth promoter. This is an antibiotic used widely in polluter for Chickens to grow faster earlier.

  It basically kills the animal’s gut bacteria, and that results in greater absorption of animal feed, and that’s how their body grows faster. Up to 70% of antibiotics manufactured in the world are used as a growth promoter in animals.

The worry
Daily use of antibiotics creates a condition among all animals including human. Daily diet of antibiotics when becomes routine does not work as anti- biotic and leads to anti biotic resistant bacteria, that means if an infection happens due to bacteria, the medicine will no longer be effective. 

So, the extensive usage of Colistin in animals leads to generation of colistin-resistant bacteria in poultry and freshwater fish. The use of chicken litter as a manure in agriculture results in the transmission of the colistin-resistant bacteria to vegetables.

There is a greater risk of transmission of colistin-resistant bacteria from fresh vegetables and meat to humans. Though cooking kills the bacteria, the possibility of cross-contamination of the bacteria prior to cooking serves as mode of entry into humans. 
Around the Globe:
Though colistin-resistant bacteria have been found in food samples in more than 30 countries, this is the first time researchers in India have looked for and found them in fresh food. 
In India, Colistin-resistant bacteria were found in 46% vegetable, meat and fish samples in Chennai A study carried out in Chennai has found bacteria resistant to colistin drug, a last-line antibiotic, in 51 of the 110 (46%) fresh food samples (poultry, mutton, fish, and vegetables) tested. 
Many countries including China have already banned the use of colistin as a growth promoter. India is now planning a similar ban. 
More importantly, the researchers, led by Dr. Abdul Ghafur of Apollo Cancer Institute, Chennai, have for the first time uncovered the mechanism by which Klebsiella pneumoniae bacteria in food samples develop resistance to colistin
