Superbugs can emerge from excessive use of antibiotics in animals
Animals stuck on factory farms around the world are often kept in poor, low welfare conditions. They are typically overcrowded, with no space to display their normal behaviours. As a result, these stressed animals are more likely to fall ill. In order to prevent sickness in these poor conditions, antibiotics are often used preventatively to reduce disease risk.
Such overuse can contribute to the rapid rise and spread of bacteria that are resistant to medicines used to fight infections. These resistant bacteria or ‘superbugs’ are carried off farms via water, air, workers, insects, wildlife, and meat, where they may eventually reach humans. Superbugs are bacteria that are resistant to the medicines that cure life-threatening illnesses.
According to the World Health Organization (WHO), superbugs were responsible for 1.27 million deaths in 2019 due to antibiotics no longer being effective.
The low-welfare conditions that contribute to the rise to superbugs can also cause diseases like bird flu or swine flu to emerge from factory farms and transfer to humans. Keeping large numbers of genetically similar animals in tightly packed conditions can increase the risk of disease spread and mutation. One day this could even lead to the next global pandemic.
This is why the transition to eating less meat and a high-welfare global food system is vital, and putting an end to low-welfare factory farms is needed.
