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.

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

“One of New York Times Top 10 Books of 2009” (Dwight Garner)

"Captivating... By turns edgy, moving, and hilarious, Farm City marks the debut of a striking new voice in American writing." --Michael Pollan, author of The Omnivore's Dilemma and Food Rules

When Novella Carpenter--captivated by the idea of backyard self-sufficiency as the daughter of two back-to-the-earth hippies--moves to a ramshackle house in inner-city Oakland and discovers a weed-choked, garbage-strewn abandoned lot next door, she closes her eyes and pictures heirloom tomatoes, a beehive, and a chicken coop.

What starts out as a few egg-laying chickens leads to turkeys, geese, and ducks. And not long after, along came two 300-pound pigs. And no, these charming and eccentric animals aren’t pets....

Farm Sanctuary: Changing Hearts and Minds About Animals and Food

Farm Sanctuary: Changing Hearts and Minds About Animals and Food
by Gene Baur (Author)


Leading animal rights activist Gene Baur examines the real cost of the meat on our plates -- for both humans and animals alike -- in this provocative and thorough examination of the modern farm industry.

Many people picture cows, sheep, pigs, and chickens as friendly creatures who live happily within the confines of a peaceful family farm, arriving as food for humans only at the end of their sun-drenched lives. That's what Gene Baur had been told -- but when he first visited a stockyard he realized that this rosy depiction couldn't be more inaccurate.

Amid the stench, noise, and filth, his attention was drawn in particular to one sheep who had been cast aside for dead. But as Baur walked by, the sheep raised her head and looked right at him. She was still alive, and...

The Self-Sufficient Family Farm: How to Create a Diversified Small Farm on Next to Nothing

The Self-Sufficient Family Farm: How to Create a Diversified Small Farm on Next to Nothing


Are you tired of paying high prices for fresh vegetables, meat and eggs at the grocery store? Would you like to have the security of knowing exactly what is in your family’s food because you produced it yourself? Would you like to eventually turn your diversified small farm into a sustainable business? If so, this book is for you.

Our family was "green" before green was the in thing to do...we had gardens and livestock out of economic necessity when I was a child. As an adult, I produced most of my own food on my own properties until I found myself actually having to move to the Mojave Desert of Southern California, just outside of Los Angeles. I was appalled at how little urbanites know about food production!
My purpose is to try to pass on all of those old but very...

Livestock Farm of a poor man

I wrote this book after a detailed research for one year and nine months in an animal farm belonging to a person from Serbia - Serbian Banat, 37km from Jimbolia - Timisoara, Romania.

The things written bellow are real. I am an Zootechnical Engineer (Zootechnical college graduate, went to an Agricultural high school, veterinary profile). I worked for twenty-five years in agriculture having different jobs such as veterinary technician, selection technician at the former OJRSA Suceava, then selection engineer in the same OJRSA Suceava, head of an animal farm, and director of a fattening bulls company which had 4500 animals. I was always interested in the application of technology. I’m based from Calafindești, Suceava County, Romania.

Animal Farm
by George Orwell (Author), Ian Woodldridge (Translator)


George Orwell’s 1945 satire on the perils of Stalinism has proved magnificently long-lived as a parable about totalitarianism anywhere—and has given the world at least one immortal phrase: “Everyone is equal, but some are more equal than others.”This new dramatization sticks very closely to the book, and the production has toured all over England, Scotland, Wales and Romania in Orwell’s centenary year. “Dare I say it . . . as good as the book.”—Guardian
