Environmental health risks of livestock farming

September 27, 2011
More exacerbations in lung patients, Q fever risk increasing with number of livestock close by

Amsterdam, The Netherlands: Emissions from livestock farms cause asthma and COPD patients living nearby to experience more exacerbations, according to research presented today at the European Respiratory Society's Annual Congress in Amsterdam.

Also, chances of contracting Q fever from nearby sheep and goat farms increased with the number of animals rather than with the number of farms, the research found, hinting at higher health risks from 'mega farms'.

The researchers, from Utrecht University, measured increased levels of particulate matter containing microbes and microbial toxins near livestock farms. They studied health effects by screening medical records from 50 general practitioners servicing 200,000 patients in regions with high and low densities of livestock farms.

In regions with many livestock farms, doctors reported less asthma, COPD, upper respiratory tract infections and hay fever, a result that mimics some earlier studies that saw less allergies in children who grown up on farms. In this study, the medical records did not specify whether symptoms were allergy- related, so the researchers do not know whether the effect is indeed limited to allergies.

The research however also showed that in areas with many livestock farms, people who suffer from asthma or COPD developed twice as much pneumonia and upper respiratory tract infections than people in regions with little livestock activity. The overall prevalence of pneumonia also was higher in high-density areas.

The study period included an unusually severe outbreak of Q fever, an infectious disease of cattle, sheep or goats, which can cause flu-like symptoms and pneumonia in humans. Between 2007 and 2010, close to 4,000 people in the Netherlands became ill; at least ten of them died.

The researchers found that the risk of contracting Q fever increased with the proximity of sheep farms or goat farms. An even stronger correlation was found between Q fever risk and the number of animals kept in the area, suggesting that mega farms could bring more environmental health risks than smaller farms.

The study contributes to on-going debates about intensive animal farming in densely populated regions in countries such as Germany and the Netherlands.

Lead researcher Dr Lidwien Smit said: "Our study is one of the first to show that living close to farms leads to exacerbation of symptoms for people with lung conditions and that during a Q fever outbreak, the risk of contracting Q fever increased with the number of livestock animals kept close by."

"The presence of two resistent forms of protozoons, the oocysts from the Cryptosporidium genus and cysts of the Giardia genus, is one of the greatest public health problems in water supply, because these parasites can easily survive our water treatment systems", José Antonio Castro Hermida, a scientist at the Galician Institute for Food Quality in the Xunta de Galicia (regional government), tells SINC.

[413519] BRAIN: FIRST LANGUAGE GENE FOUND (pp519-523; N&V) Researchers led by Anthony Monaco at the Wellcome Trust Centre for Human Genetics, University of Oxford, UK, have pinpointed the first gene to be definitively linked to language, in this week's Nature. The gene is mutated in the 'KE' family, some members of which have difficulty in controlling their lip and tongue movements, difficulty in forming words, and difficulty in using and understanding grammar. The gene codes for a 'transcription factor': a protein that switches genes on and off. The genes it interacts with might therefore signpost the way through the genetic network of language learning and use. It is known to be active in

Humane Livestock Handling: Understanding livestock behavior and building facilities for healthier animals

Humane Livestock Handling: Understanding livestock behavior and building facilities for healthier animals
by Temple Grandin (Author)


Temple Grandin, North America's most influential advocate of humane livestock treatment, has spent her life developing stress-free facility designs and standards of humane management. In an environment of growing concern regarding large factory-farming practices, Grandin is a voice of reason explaining the benefits of keeping animals calm through every phase of their lives — benefits that include safer working conditions, higher yields of marketable meat, better-quality meat, and, of course, more humane conditions for the animals.

The first half of Humane Livestock Handling reviews the natural behavior and temperament of cattle. Working with the animals' natural instincts, Grandin describes low-stress methods for moving cattle on pastures, paddocks, and feedlot pens. Slow,...
