Docs ask: Does “do no harm” apply to food served in hospitals?
“First, do no harm” is a core tenet taught to aspiring medical professionals. In June this year, the Sustainability Task Force of the UCSF Academic Senate drafted a resolution asking UCSF food services to phase out of all procurement of meat produced with the use of non-therapeutic antibiotics. Given that many scientists believe that the use of prophylactic antibiotics for livestock production causes antibiotic resistance, how can physicians stand by while hospitals serve foods from antibiotic-treated animals to patients that increasingly suffer from antibiotic-resistant infections? If not, what can they do about it?
In a few weeks, local organizations will take up the hard questions again with their peers at UCSF Medical Center. Going beyond meatless Mondays, healthcare professionals, Healthcare Without Harm, and PEW Charitable Trusts, all see antibiotic-free meat and poultry as the next step in advocating for healthier food.
Fixing this problem for most of us is as simple as buying organic meat or free-range antibiotic-free alternatives. For a UC medical center, however, it is far from simple. Price, supply and food budgets are all based on past purchase history. It takes considerable will, consensus, and commitment to “do no harm” before administrators will agree to pay double or triple the cost for meat produced without these drugs. Cattle fed regular antibiotics to fatten them up, even when they are healthy, are more profitable up the entire food chain.
The advocates for the healthcare side want to know: Can this become a priority for us and our hospitals? Where are the suppliers of antibiotic-free products? Are they selling the cuts we need? How can change be “phased in” to allow the distribution chain to supply this emerging demand? In a hospital, should food be one of the least expensive of many pricey services?
The producers are likely to have questions, too. Is this a lucrative opportunity for smaller alternative suppliers, or is it a political battle to force big agriculture to comply? If producers start down this road, how many bumps will they encounter along the way? Why should they risk supplying a new market when business is risky as is? How long will they commit to these products?
It seems logical that low production costs alone should not threaten the public health of a nation or even just the health of the nation's vulnerable citizens. If these drugs were never allowed for feeding in the first place, producers would be on a level playing field and beef might be more than a commodity. Likewise, ethical food standards have defined humanity for thousands of years. So now that there is more food, more technology and more choice, why is it more difficult to make changes that ultimately benefit everyone?

California's dry winter is leaving west side cattle hungry
The long rainless winter resulted in grass growth on the west side of the San Joaquin Valley about 80 percent less than usual, reported John Holland in the Modesto Bee. Spring rain pushed somewhat more growth on the valley's east side, which was charted at 55 to 70 percent less than normal.
Theresa Becchetti, UC Cooperative Extension advisor in Stanislaus and San Joaquin counties, a livestock expert, and Diana Waller, district conservationist for the U.S. Natural Resources Conservation Service, reported the conditions in a letter last month to county and federal agriculture officials.
Fall 2011 rain helped germinate seeds, but "unfortunately, that is where it ended," they wrote.
A cattle producer quoted in the story said the poor feed conditions are offset somewhat by beef prices that have remained strong.
The USDA reported that nonirrigated range condition was poor to fair, with some higher-elevation range in good to fair condition.
Scientists target E. coli from farm to fork
The U.S. Department of Agriculture is funding the $25 million, coast-to-coast project, to which UC Davis is providing expertise in livestock health, foodborne disease and consumer food marketing.
The project, announced Jan. 23 by the USDA, aims to reduce the occurrence of and public health risks associated with Shiga toxin-producing E. coli. The research effort is led by the University of Nebraska, Lincoln.
UC Davis researchers collaborating in the project include James Cullor, a professor in the School of Veterinary Medicine; Christine Bruhn, a food science marketing specialist and director of the Center for Consumer Research; and Terry Lehenbauer, director, and Sharif Aly, assistant professor, both of the Veterinary Medicine Teaching and Research Center in Tulare.
Cullor and his colleagues in the veterinary school's Dairy Food Safety Laboratory -- in Davis and Tulare -- will conduct research aimed at reducing the microbial counts on cattle hides during processing, looking for ecologically responsible methods for enhancing food safety. They also will test radiofrequency technologies, which use electrical currents oscillating at specific frequencies to inactivate E. coli on beef carcasses during processing.
Bruhn will collaborate with North Carolina State University and Kansas State University to reduce health risks associated with undercooked hamburgers. The researchers will encourage television food programs to include safe food-handling practices and messages.
In addition, Bruhn will work with health care professionals to raise the number of food-handling messages directed toward consumers who are at increased risk for foodborne illness, especially children and people with diabetes. She also will investigate consumer interest in the use of irradiation or high-pressure technologies to enhance the safety of ground meat.
Lehenbauer, Aly and their colleagues at the Veterinary Medicine Teaching and Research Center will participate in animal research needed for understanding the epidemiology and ecology of non-Shiga toxin-producing E. coli, after information from preliminary studies is used to develop the scientific protocols for these animal-sampling projects. The research team will focus on dairy cattle, including male Holstein cattle that are being raised for beef production
Other participants are the University of Delaware, New Mexico State University, Texas A&M, Virginia Tech, the University of Arkansas, the USDA's Agricultural Research Service, and a consortium of government, academic and industry scientists and food safety professionals.
Not a lot of greenhouse gas is from animal ag
There's been some confusion in recent years about the impact of animal agriculture on global warming. UC Davis Cooperative Extension air quality specialist Frank Mitloehner will share his findings on the subject this month during a free webinar on the eXtension website, according to an article in Pork magazine.
The 2006 United Nations report "Livestock's Long Shadow" said the livestock sector is responsible for 18 percent of greenhouse gas emissions, a higher share than transportation. Mitloehner said livestock's contribution is more like 3 percent, yet wide distribution of the misinformation has put Americans and others on the wrong path toward solutions.
The webinar, which will include information from Mithoehner's report "Clearing the Air: Livestock's Contribution to Climate Change," is at 11:30 a.m. Pacific Time June 11. Forum participants will have the opportunity to ask questions, post comments, upload photos and share their experiences. All the details, including links to background information and to the webinar, are in this eXtension flyer.

Animal feed generates lots of valley ozone
Scientists have been puzzled by the fact that the San Joaquin Valley often suffers high ozone levels even though the mostly rural, agricultural domain has fewer cars and trucks than big cities. Research by UC Davis scientists is now showing that some of the ozone in the valley is being generated by fermented animal feed, according to a story posted yesterday on the website Science News.
While ozone provides a protective barrier for the earth in the stratosphere, it is an unwelcome molecule to have around where people are breathing. Ozone (O3) is a powerful oxidizing agent, far stronger than O2. It can harm lung function and irritate the respiratory system.
The UC Davis team, led by environmental engineer Cody Howard, tested seven types of animal feed in a one-meter-square tented chamber, according to writer Janet Raloff, author of the Science News story. They added a mix of gases that matched the valley’s air and simulated sunlight with lamps. The result was lots of ozone.
Corn silage generated about 125 parts per billion ozone, alfalfa silage a little less, and mixed oat-wheat silage 210 ppb, Raloff reported. These emissions pale in comparison to cars. However, because the San Joaquin Valley has so much silage to feed its animal agriculture industry, the feed appears to be the single biggest contributor to the region’s ozone problem, the story said.
Cars and light-duty trucks in the valley can generate 13 metric tons of ozone per day, while feed for the valley’s 10 million head of dairy cattle can produce 24.5 million tons of ozone per day.
