Farmers need help to plow through new food safety regulations

2013-10-01
(Press-News.org) Agricultural extension educators should take a flexible approach in teaching farmers about the changing landscape of food safety regulations, according to Penn State researchers. "We should try to focus on creating programs for growers so that they can do what they need to do economically to stay viable as they face new regulations and standards that can be complex and intimidating," said Daniel Tobin, doctoral candidate in agricultural economics, sociology and education. The researchers said that farmers who attended an extension workshop on food safety standards to reduce of the risk of foodborne illnesses understood the material, but many hesitated taking action on that new information. "We know that skills and attitude are part of the puzzle to try to help farmers make changes necessary to comply with standards," said Tobin. "However, the new standards may intimidate growers, and it becomes much harder to try to change behaviors with a one-size-fits all approach to education." The recently passed Food Safety Modernization Act set safety standards on how farmers grow, harvest and handle fresh produce to reduce the risk of foodborne diseases. The new regulations to minimize food safety risk include testing for water safety and better managing manure storage. To add to the complexity, small farms -- operations with under $25,000 in annual food sales to local stores and consumers -- are exempted from these federal regulations. However, distributors and grocery stores are increasingly implementing their own separate standards on food safety, said Tobin, who worked with Joan Thomson, professor emerita, and Rama Radhakrishna, professor, both of agricultural economics, sociology and education, and Luke LaBorde, associate professor of food science. Current food safety training programs typically focus on the USDA standards, even though many of the farmers run small operations that are exempted from the standards, said Tobin. A better approach may be to create customized and more modular training programs that fit the individual farmers' needs. "We can provide those types of workshops that look at the federal standards, but, because growers see it as being so messy, it makes it harder for them to adopt the practices," said Tobin. "We may want to take a step back and adopt a flexible approach that can deliver the information to different groups based on different needs." The researchers, who released their findings in the online version of Food Control, examined surveys taken by 176 farmers immediately before and immediately after they attended a one-day workshop on USDA standards on good practices. The farmers then completed the survey again six months after the workshop. The results showed that the farmers' knowledge of the standards improved after they took the workshop. However, the delayed evaluation signaled that their confidence in implementing the standards decreased during the months after the training session. "What it indicates is that a linear process between knowledge and action does not always exist," said Tobin. "New knowledge and new skills do not always translate to increased action." Because some farmers who run small operations that are not exempt from private and government requirements may believe that foodborne illness is mostly a concern of large farms, the researchers also suggested that extension educators convey the risks of avoiding and benefits of enhancing food safety on the farm. ### The USDA and Penn State Extension supported this work.

Study: Acidity can change cell membrane properties

2013-10-01
Of all the amazing technologies humans have developed, none has matched the complexity of the fundamental building block of nature: the living cell. And none of the cell's activities would be possible without thin lipid membranes, or bilayers,that separate its parts and regulate their functions. Understanding and controlling bilayers' properties is vital for advances in biology and biotechnology. Now an interdisciplinary team of Northwestern University researchers has determined how to control bilayers' crystallization by altering the acidity of their surroundings. The ...

Protecting underground pipelines from corrosion in sub-zero environments

2013-10-01
Northern Canada's permafrost and semi-permafrost environment is a huge challenge for designing and engineering underground pipelines, and a critical aspect of protecting both the pipeline and this sensitive environment involves the design of an effective corrosion protection system. One of the most common methods to protect buried infrastructure—such as oil and gas transmission pipelines —from corrosion is the application of an external coating. "Although great advances have been made within the past 30 years in terms of coatings reliability and longevity, it's still ...

NREL releases new roadmap to reducing solar PV 'soft costs' by 2020

2013-10-01
The Energy Department's (DOE) National Renewable Energy Laboratory (NREL) recently issued a new report, "Non-Hardware ('Soft') Cost-Reduction Roadmap for Residential and Small Commercial Solar Photovoltaics, 2013,"PDF funded by DOE's SunShot Initiative and written by NREL and Rocky Mountain Institute (RMI). The report builds off NREL's ongoing soft-cost benchmarking analysis and charts a path to achieve SunShot soft-cost targets of $0.65/W for residential systems and $0.44/W for commercial systems by 2020. Non-hardware costs — also referred to as soft, balance of system, ...

Understanding soil nitrogen management using synchrotron technology

2013-10-01
As food security becomes an increasingly important global issue, scientists are looking for the best way to maintain the organic matter in soils using different methods of fertilization and crop rotation. Increasing the organic matter in soils is key to growing crops for numerous reasons, including increased water-holding capacity and improved tilth. Scientists have recently used the Canadian Light Source (CLS) to evaluate the effects of various sources of supplemental nitrogen fertilizer on the chemical composition of soil organic matter. Results of their experiments ...

Tests in mice identify compound that may keep survivors of brain aneurysms from succumbing to stroke

2013-10-01
Johns Hopkins researchers, working with mice, say they have identified a chemical compound that reduces the risk of dangerous, potentially stroke-causing blood vessel spasms that often occur after the rupture of a bulging vessel in the brain. They say their findings offer clues about the biological mechanisms that cause vasospasm, or constriction of blood vessels that reduces oxygen flow to the brain, as well as potential means of treating the serious condition in humans. When an aneurysm — essentially a blister-like bulge in the wall of a blood vessel — bursts, blood ...

Scripps Florida scientists develop new process to create artificial cell membranes

2013-10-01
JUPITER, FL – October 1, 2013 – The membranes surrounding and inside cells are involved in every aspect of biological function. They separate the cell's various metabolic functions, compartmentalize the genetic material, and drive evolution by separating a cell's biochemical activities. They are also the largest and most complex structures that cells synthesize. Understanding the myriad biochemical roles of membranes requires the ability to prepare synthetic versions of these complex multi-layered structures, which has been a long-standing challenge. In a study published ...

What makes us left or right handed? New study rules out strong genetic factors

2013-10-01
Around 10 per cent of the UK is left handed — and that percentage remains consistent in many populations around the world. But why exactly someone is left or right handed remains unclear. New research from The University of Nottingham's Professor John Armour and Dr Angus Davison, in collaboration with UCL's Professor Chris McManus, has ruled out a 'strong genetic determinant' in influencing handedness. The researchers conducted a twin study examining the whole genome — which contains hereditary information — of nearly 4,000 subjects from the London Twin Research Unit ...

Bad luck? Knocking on wood can undo jinx: study

2013-10-01
Knocking on wood is the most common superstition in Western culture used to reverse bad fortune or undo a "jinx." Other cultures maintain similar practices, like spitting or throwing salt, after someone has tempted fate. Even people who aren't particularly superstitious often participate in these practices. A new study from the University of Chicago Booth School of Business finds that these superstitions actually do "reverse" perceived bad fortune. People believe that negative outcomes are especially likely after a jinx. If someone says, "No one I know will ever get ...

Regular primary care visits lower colorectal cancer incidence, death, and all-cause mortality

2013-10-01
1. Regular primary care visits lower colorectal cancer incidence, death, and all-cause mortality Medicare beneficiaries with more visits to their primary care physician (PCP) have lower colorectal cancer (CRC) incidence, CRC-specific mortality, and all-cause mortality. CRC is preventable with appropriate screening and polypectomy, yet many of the people who could benefit from it either are not screened, or do not start screening early enough. Recommendations from physicians are the strongest predictors of adherence to CRC screening guidelines. Researchers hypothesized ...

Medicare plans understate risky prescribing rates

2013-10-01
PROVIDENCE, R.I. [Brown University] — A new study reveals widespread inaccuracy in a quality measure that is self-reported by Medicare Advantage health plans. Researchers found that the vast majority in a sample of 172 such insurers significantly understated their rate of high-risk medication prescriptions. The average rate of prescribing at least one of about 100 medicines deemed risky for the elderly was 26.9 percent of patients over 65, according to the researchers' calculations, compared to the 21.1 percent of patients reported by the plans. The average plan, therefore, ...
