Brief version:
Robert Derlet- Director of the emergency room at UC Davis Medical Center is blaming cattle waste in water sources on people being sick and coming to the emergency room. In an article published in a peer reviewed journal- They found 15/15 sites where cattle were watering and 12/15 pack sites (those where pack stock or horses, mules, and burros were tied) to be contaminated with fecal coliforms and/or E. Coli.

"I can recall ... spots in the Sierra where tears almost want to come to your eyes, where you see cow patties right in the stream," Derlet said. "Flushing down from the Sierra, we have raw sewage."

"The overriding problem is the cattle," Derlet said. "Horses are usually along the trails and controlled by a guy who theoretically will make sure they poop away from the water."

Here is the scientific rebuttal from Drs Atwill and Tate also from UC Davis.
Proper livestock management can significantly reduce this risk, but first a few points about that risk. It has often been assumed that many pathogens shed by cattle are infectious to humans. Recent research finds this is not always the case. Several species of the parasite Cryptosporidium shed by cattle are barely infectious for humans, or not at all, and often just a few adult range cattle are carriers. Higher levels are found in young beef calves, sometimes up to 20% are carriers for a few weeks. Many types of Giardia carried by livestock are not infectious for humans. Background levels of indicators and pathogens in streams can be very low, but also quite high. Many wildlife species carry surprisingly high levels of these microbes, and make daily contributions in our watersheds.

There are many science‐based solutions and opportunities to address livestock associated risks. A grazing management tool box, if you will. For example, we can use careful placement of livestock attractants such as drinking water to move as much as 60% of cattle fecal waste away from streams. Even a few days a month spent
herding cattle away from streams will increase stream health. During summer months, almost all the C. parvum found in cattle fecal pats exposed to sunshine dies within one day due to lethal hot temperatures. Over 90% of the E. coli, C. parvum, Giardia, and Salmonella found in cattle fecal pats are not transported more than a foot during
rainfall‐runoff events. A single additional yard of rangeland soil and vegetation can often filter 30 to 90% of these microbes flowing in surface runoff. Wetlands can filter up to 90% of E. coli in runoff from grazed pastures.

My thoughts... Where do I start? This whole study is wrong in so many ways. My biggest concern is a companion paper that was published with Mike Connors California Liason for Western Watersheds Project. So, the agenda for these studies is clear- get cattle off of Federal lands. The article in the Bee went on to reference cost of grazing but only took into consideration the cost per AUM. Not that permittees also pay for fence maintenance, clear trails, help maintain a food source for America. Nope none of that was mentioned.

My second concern- The raw sewage statement. First, who drinks from creeks, lakes, or other water sources in the mountains without boiling or using some type of anti-microbial agent anyways? Secondly, wildlife do not relieve themselves in water sources? I suppose they use the outhouses set up by fish and game?

My thrid concern- Is it possible that the high levels of indicator bacteria at cattle sites are not only due to the cattle but a symbiotic relationship between wildlife and cattle concentrating animals both domestic and wild in an area? The levels of indicator bacteria were not high at backpacker sites 1/15 tested positive. I wonder how much wildlife were at these sites? You see wildlife and cattle together all the time but humans and wildlife? Nope you have to create bear world or a national park to acclimate wildlife to humans.

Fourth, I don't believe this study is unbiased. No randomization. Association with Western Watersheds. AND what does an emergency room administrator know about water quality?

Lastly, One of the comments submitted to the paper was: Cattle are a non-native ungulate species that has been destroying the environment for centuries. Hmmm... Couldn't the same be said for humans?

Emotions

There is something about animals that raises emotions in us all. Be it a goldfish swimming around in a bowl or a cow out in a large pasture, there is a connection. Unfortunately, that connection isn't what it used to be. The American public is only two maybe three generations off the farm. Food now comes from a grocery store not a farm or ranch. How did we become so disjointed and urbanized?

I believe mechanization of agriculture started the downhill slide. There was less workers needed on the farm to accomplish the same tasks. Factories in cities offered a haven for workers who were replaced by tractors, combines, and mechanical pickers.

People no longer harvested their own meat. It was bought at the grocery store or from the corner butcher. No emotions needed there. They didn't have to make sure this animal was fed, watered, or consider it's health to ensure a wholesome, nutritious, product was on the table.

What really bothers me about the whole situation is the same people who do not provide the basic comforts of life for animals or make their living from the land want to tell farmers and ranchers how to do their job. I do not go to the Ford plant and tell engineers how to make the next vehicle just because I drive a Ford pickup. I am not qualified nor do I have the experience to make such an assumption.

So why do we have ballot measures dictating how to raise animals?

Introduction

The corner post in a fence is the most important part. It must be set deep in the soil to maintain the integrity of the rest of the fence(s). The corner post is also where outlying fields meet. These fields being science, emotion, environment, agriculture, wildlife, and livestock.

This is my maiden voyage into blogging. I created this site to reflect on the agricultural community and negate some of the misconstrued information on the world wide web, mass media, and lobbying organizations. I wanted to become an advocate for the industry that feeds the nation.
