Bad meat, bad health

Recent studies¹ have shown that meat from intensively farmed animals can have lower levels of beneficial omega-3 and a less favourable ratio of omega-6 to omega-3. An inadequate intake of omega-3 and an unbalanced ratio of omega-6 to omega-3 have been linked with cardiovascular disease and certain cancers². A recent Compassion in World Farming report shows that extensively farmed animal products often contain higher levels of antioxidants, iron and lower levels of fat³. The rise of factory farming and ‘cheap’ meat has also led to significant overconsumption problems in many countries around the world; heavy red and processed meat consumption has been linked to a number of serious health-related conditions, including obesity, diabetes and cancer.

But don't just take our word for it

Heavy red meat consumption can increase the risk of some cancers developing by as much as 43%.

Food-borne illnesses

The conditions on a typical factory farm – where animals are forced to live in close proximity to one another in cramped spaces – facilitate the spread of bacterial pathogens such as E. coli and Salmonella. These can cause gastroenteritis in humans and, in extreme cases, death.

But don't just take our word for it

A large-scale UK survey found that battery-cage farms are six times more likely than non-cage farms to be infected with the strain of salmonella most commonly associated with food poisoning.

Animals and workers crammed together

Cramming animals together in their hundreds or even thousands creates the perfect conditions for diseases to be transmitted and even to mutate into more dangerous strains (Pew Commission, 2008⁶). Farm workers can play a role too; according to an article in Environmental Health Perspectives (2009⁷), industrial farm workers are a key risk for zoonotic infection as a result of their ‘routine and intensive exposure’ to the farm animals, potentially serving as a ‘bridge population’ that could transfer infections from animals to the wider public.

But don't just take our word for it

Fifty years ago, a US farmer who raised pigs or chickens might be exposed to several dozen animals for less than an hour a day. Today’s confinement facility worker is often exposed to thousands of pigs or tens of thousands of chickens for eight or more hours each day.

Antibiotics overload

Antibiotics can form an important part of good animal husbandry, preventing sick animals from suffering. However, there is an extreme overuse of these drugs in many factory farms⁹. Antibiotics are often fed to factory-farmed animals to offset the disease risks posed by overcrowding – this is carried out regardless of whether the animal is infected or not. In some countries, antibiotics are even used to promote growth**. The rampant use of antibiotics in farm animals may well be harming us, driving the development of drug-resistant bacteria, which can reduce our ability to recover from a wide range of food-borne illnesses and diseases¹⁰.

Nearly 80% of the total antibiotics distributed in 2009 in the US were for farm animals.

US Food and Drug Administration (USFDA) (2009)^11,12

* Zoonotic diseases are those diseases that can pass between animals and humans

** The use of antibiotics to promote farm animal growth is outlawed in the EU but legal in a number of countries, including the United States

But don't just take our word for it

Eating large amounts of red and processed meats increases exposure to toxins and is linked to higher rates of heart disease, cancer and obesity.

Environmental Working Group (EWG) (2011)¹³

Animal waste from large factory farms is threatening our health, the water we drink and swim in, and the future of our nation's rivers, lakes, and streams

National Resources Defense Council (2001)¹⁴

Seventy-five percent of the antibiotics used on livestock are not absorbed by the animals and are excreted in waste, posing a serious risk to public health.

Worldwatch Institute (2011)¹⁵

FDA believes the use of medically important antimicrobial drugs in food-producing animals for production purposes (e.g., to promote growth or improve feed efficiency) represents an injudicious use of these important drugs.

So what?

Factory farming threatens our health. By taking action against factory farming, we are not just creating a food and farming revolution; we are also creating a healthier world for ourselves.
