A Kenyan trend in farmers giving their animals antibiotics has seen some farmers drugging their sick flock instead of going to the vet.

Many farmers avoid veterinary services because they see it as an extra cost.

Some have given antibiotics to the point of overdose and one farmer told the BBC that she gives her chickens antibiotics when they are well to prevent them from getting ill.

The World Health Organisation (WHO) has warned farmers against using antibiotics to treat their animals, saying it can harm the humans who eat the meat.

A study by the Global Antibiotic Resistance Partnership warns that Africa will be hit hardest by a growing resistance to antibiotics.

It adds that 70% of antibiotics imported into Kenya are given to chickens, pigs and cows.
