The reduction and absolute banning of antibiotics in farmed animals has shown dramatic changes in the antibiotic residues,but the identification of some antibiotic resistance strains that was not used even during production,has beam the search on another possible route of transmission.
The environment is the mixing media where various pathogens interact, pathogens from man,animals are exchanged freely .Antibiotics released into the environment may be spread through plants which later are consumed by humans, or by livestock.
The consequence is that relatively harmless conditions such as diarrhea caused by resistant coli bacteria or salmonella bacteria become dangerous or even lethal.
Drugs discharged into the environment are a problem in many parts of the world and antibiotics are spread in nature through urine from animals and humans, and many unfortunately have a very long life span.
The problem is very pronounced in many African countries because of poor sanitation conditions .
The quality of drugs available to man and animals also play a role in development of resistance,many countries with poor drug regulations where concentrations of active ingredients are not accurate,or the active ingredient is not even in the preparation( fake drugs).
This results in repeated treatment where the bacteria is not destroyed but becomes resistant to the drug.The environment is the mixing vat,and unless proper disposal of drugs,feces are incorporated into sanitation laws the problem will persist.
