Intensive Farming Practices Contribute to Spread of Animal Pathogens to Humans

Scientists at the Universities of Bath and Sheffield studied how the Campylobacter jejuni bacterium spread from cattle to humans. Their study, published in Proceedings of the National Academy of Sciences, concluded that increased movement of animals globally and intensive farming practices provide the perfect environment for spread of pathogens to humans. Environmental change and increased contact with farm animals are also contributing factors in bacterial infections of animals crossing over to humans. Researcher Dave Kelly noted, “Human pathogens carried in animals are an increasing threat and our findings highlight how their adaptability can allow them to switch hosts and exploit intensive farming practices.”
