Intensive farming provides the ideal conditions for bacteria and viruses to spread between animals and humans, increasing the risk of epidemics, experts have found.The warning comes after researchers conducted a genetic analysis of the bacteria Campylobacter jejuni, which is commonly found in farmed cattle.ADVERTISEMENTThis microorganism is also the most common bacterial cause of human gastroenteritis, according to the (WHO).ADVERTISEMENTThe team found that the strains of the bug that are specific to cattle first emerged in the 20th century, coinciding with large increases in the number of...…Intensive farming provides the ideal conditions for bacteria and viruses to spread between animals and humans, increasing the risk of epidemics, experts have found.The warning comes after researchers conducted a genetic analysis of the bacteria Campylobacter jejuni, which is commonly found in farmed cattle.ADVERTISEMENTThis microorganism is also the most common bacterial cause of human gastroenteritis, according to the (WHO).ADVERTISEMENTThe team found that the strains of the bug that are specific to cattle first emerged in the 20th century, coinciding with large increases in the number of...WW…
