National Farmers Union reiterated its opposition to the Smithfield-Premium Standard Farms merger directly to officials at the U.S. Department of Justice (DOJ) today.

In a meeting with DOJ officials, NFU and representatives from other organizations expressed concerns about the impact the proposed acquisition will have on independent hog producers, processing facility employees and consumers. Last month, Smithfield Foods, Inc., announced their intent to purchase Premium Standard Farms; consolidating the two largest hog producers in the U.S.

Upon learning of the acquisition, NFU immediately called upon U.S. Attorney General Alberto Gonzales to conduct an in-depth investigation and analysis of the proposed deal. NFU later built a coalition of like-minded organizations that have been working together to stop the transaction from going forward.

Department of Justice officials are in the process of reviewing the proposed merger and listened to the concerns of NFU and the other organizations at the meeting. NFU President Tom Buis said he was pleased Justice Officials agreed to meet with concerned interests.

"We believe this acquisition will result in the solidification of alliances that will exacerbate concentration in not only livestock processing, but also in production," Buis said. "This could lead to an inordinate and excessive control of livestock and influence on markets. It could also lead to manipulation of consumer retail prices for pork and beef."

A late September NFU-organized letter gained the support of fifteen organizations that wrote Gonzales requesting an investigation.

New measurements of soot produced by traditional cook stoves used in developing countries suggest that these stoves emit more harmful smoke particles and could have a much greater impact on global climate change than previously thought, according to a study scheduled to appear in the Nov. 1 issue of the American Chemical Society journal Environmental Science & Technology.

Perhaps as many as 400 million of these stoves, fueled by wood or crop residue, are used daily for cooking and heating by more than 2 billion people worldwide, according to the study's lead authors, Tami Bond, Ph.D., and doctoral candidate Chris Roden of the University of Illinois, Urbana-Champaign. In a field test in Honduras, the researchers found that cook stoves there, which are similar to those used in other developing nations, produce two times more smoke particles than expected, based on previous laboratory studies. These dark, sooty particles, which are darker than those produced by grassland or forest fires, have a climate warming effect because they absorb solar energy and heat the atmosphere, according to Roden.

In earlier work, Bond estimated that burning firewood -- the principal fuel for cook stoves in the developing world -- produces 800,000 metric tons of soot worldwide each year. In comparison, diesel cars and trucks generate about 890,000 metric tons of soot annually. These two sources each account for about 10 percent of the soot emitted into the world's atmosphere each year, she said.

In addition to its environmental effects, smoke from cook stove fires is a major cause of respiratory problems, eye infections and tuberculosis, according to the researchers.

"Emissions from wood cook stoves affect the health of users -- especially of women and children -- neighborhood air quality, and global climate. Reducing these emissions, through the use of cleaner burning stoves and fuels, should have far-reaching benefits," Bond said.

In the past, scientists have relied on laboratory measures of pollutants from cooking fires because field tests have been difficult to conduct, in part, because of limited access to remote locations and a lack of power to operate the scientific equipment, according to Roden. To get a more accurate measure of the environmental impact of these stoves, Roden and Bond developed a portable battery-operated sampling cart, which includes sensors for measuring carbon dioxide and carbon monoxide, particle soot absorption, particle color and concentration, which they took to Honduras for field tests.

Honduras is typical of Central American countries, where more than 80 percent of families cook their meals over open wood fires, according to Trees, Water & People, an American nonprofit agency which, along with the Honduran Association for Development, helped facilitate this study. In most cases, these families can't afford or don't have access to electricity, gas or alternative fuel sources.

"We expected field measurements to be different from lab measurements, and we suspected the amount of black carbon from these stoves would be higher than open burning, but we were surprised by how much," Roden said.

Trees, Water & People and other nonprofit agencies are distributing new low-cost, wood-burning cook stoves in Honduras and other Latin American countries that appear to be less polluting and more fuel efficient, according to the researchers. However, further analysis is needed.

"Designing and distributing improved cook stoves may be an effective method of mitigating global climate change, and can improve the health of the users," Roden said. "However, the cook stoves must be well designed and properly tested. They must be built with local traditions and practices in mind and must be easy to use, or they may become expensive doorstops."
