Farm Animal Welfare for Better Public Health

Factory farming endangers animal and human health

Through its significant impact on the environment and the conditions in which farm animals are kept, factory farming fuels the risk of infectious diseases in both humans and animals, as well as the threat of antimicrobial resistance.

To protect human health, it is crucial to improve the welfare of farmed animals and reduce the overall number of animals raised for farming. 

To achieve this, FOUR PAWS is working with international institutions and policymakers to prioritise the welfare of farmed animals in their plans to combat public health threats.

Why is factory farming the problem? 

Did you know that zoonoses — diseases that spread between animals and humans — account for roughly 60% of all infections in humans and 75% of all emerging infectious diseases?1 They are responsible for around 2.5 billion cases of human illness and approximately 2.7 million human deaths each year.2 This situation is likely to worsen as intensive farming expands and intensifies.3 We cannot allow this to happen.

The cruel conditions in which animals are kept in factory farms create the perfect environment for pathogens to amplify, mutate, spread and to develop antibiotic resistance. Factory farming is the main driver of agricultural expansion, leading to significant changes in land use.4,5 This expansion disrupts the natural boundaries between ecosystems, creating environments where pathogens thrive and are transmitted between wild animals and humans.6 Intensive farming is also fuelling climate change and biodiversity loss.7,8 All these factors lead to the emergence and spread of infectious diseases.  

We are focused primarily on:

Animal Farming and Antimicrobial Resistance 

If we don´t take action, by 2050, antimicrobial resistance could cause 39 million deaths and bring economic losses comparable to the 2008 financial crisis.9 Antimicrobial resistance (AMR) is one of the greatest threats to our health. Factory farming, accounting for over 70% of the worldwide use of antibiotics, is one of its main drivers.10

A significant reduction in the use of antimicrobials in agriculture is urgently needed and is only possible if we address the root causes that make antibiotic treatments necessary — learn more on this topic.

Avian Influenza: A Growing Threat to Public Health

Highly pathogenic avian influenza (HPAI), otherwise known as 'bird flu' has reached unprecedented geographical extent. Spanning across continents, including Antarctica, with record numbers of outbreaks and devastating effects on animal health and welfare.11,12

Avian influenza is causing mass mortality in domestic and wild birds, and also affecting domestic and wild mammals. The rising number of infections in mammals and of mammal-to-mammal transmissions have renewed the concerns that the virus is further adapting to mammals and could potentially lead to the next pandemic.13 Find out more here.

FOUR PAWS calls on policymakers to:

Promote higher animal welfare in farming

To improve the health of animals and protect human health. 

Reduce the number of animals farmed

Transition towards sustainable, diverse, and plant-rich food systems that reduce environmental pressure.

Reduce the number and size of farms

As well as stocking densities in farms, to lower disease risks for animals and humans. 

Support genetic diversity in farming

And local breeds as they are less prone to diseases compared to high-yield breeds.
