Kansas State University surveyed 2,000 people by mail in Wichita, Kan., and Los Angeles – 1,000 in each city – to find out their reactions to various food safety situations. About 30 percent responded to the Food Safety Consortium-funded survey with the higher response rate coming from Wichita.
The avian flu scenario presented in the survey supposed that a case of the disease was found in Montana and asked how respondents’ poultry consumption would change.
“Seventy percent of Wichitans said their consumption wouldn’t change, whereas the corresponding percent for Los Angeles was 50 percent,” said Sean Fox, a KSU agricultural economics professor who supervised the research. Fourteen percent of Los Angeles respondents said they would stop consuming poultry entirely while only 7 percent in Wichita said they would do so.
Fox explained that the survey was designed to quantify the potential impact on the poultry industry of a domestic avian flu outbreak. No outbreaks have occurred in the United States, but a 2003 outbreak in Southeast Asia spread to 41 other countries in the next four years. More than 300 million poultry in Asia were lost.“We figured the risk to commercial poultry flocks in the U.S. was very low, but
The discovery of avian flu in a U.S. flock might result in restrictions against the nation’s poultry by importing countries. If that happened, Fox noted, prices of U.S. birds would decrease and production would then be reduced.
“We don’t yet have estimates of what the supply response would be,” Fox said. “Knowing or getting an estimate of what the demand reduction might be would give us an estimate of what the price reduction would be.”
The different reactions from survey respondents in Wichita and Los Angeles might be explained by Kansans’ greater familiarity with agricultural issues, Fox said. In Los Angeles, those who did respond may be people who are generally more concerned about food safety issues.
The KSU survey also covered other food safety-related topics. Asked about how they reacted to the contamination of spinach by E. coli O157:H7 in the summer of 2006, 45 percent of the Los Angeles respondents reported no change in their purchasing habits. In Wichita, 55 percent said they didn’t change their spinach purchases.
Concerning irradiation of food as a way to kill pathogenic bacteria, 40 percent of the respondents had not heard of the procedure prior to being questioned in the survey. When provided with a description of the technology, the Los Angeles respondents were less likely to buy an irradiated food product than those in Wichita.
The survey also showed that Wichita respondents preferred to purchase cheaper meats from animals treated with antibiotics, but Los Angeles respondents preferred antibiotic-free meats at a higher price.
Also, Wichita respondents reported they ate more beef than the Los Angeles respondents, who ate more vegetables than their Wichita counterparts. Both cities reported about the same level of chicken consumption.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
