Several experts addressed home-based food safety issues in “Consumers’ Refrigerators: A Danger Zone” Monday at the Institute of Food Technologists’ Annual Meeting and Food Expo in New Orleans.
“You don’t have to go to a restaurant or to a party to get sick,” said Fur-Chin Chen, Ph.D., a microbiologist at the University of Tennessee. He found a variety of pathogens in a quarter of the refrigerators he inspected during a recent study. Vegetable bins were the most contaminated.
Armed with such information, your home refrigerator can slow you down with more than a stomach ache if you fail to keep your food cold or to eat and store ready-to-eat foods by recommended dates.
“There is a disconnect between food safety practices and people’s confidence in preparing foods safely. It’s very hard to change behaviors,” said Danielle Schor, R.D., and a senior vice president of the food safety division of the International Food Information Council (IFIC), a nonprofit organization that addresses consumer education.
IFIC has taken up issue of safe-refrigeration cause with a customized campaign. The campaign’s main message to consumers is to purchase thermometers, keep refrigerator temperatures at 40 degrees Fahrenheit or below, and monitor several times a day.
Aside from throwing out ready-to-eat foods by package storage dates, refrigerators need a weekly cleaning, a practice that consumers avoid. One study shows that approximately 50 percent of consumers clean their refrigerators once a month. But because consumers fail to clean thoroughly, scientists say that figure is likely exaggerated.
The best regime is to clean your refrigerator (which shouldn’t be more than 10 years old) inside and out with dish soap once a week. Allow the shelves and drawers to air dry, said Sandria Godwin, Ph.D., R.D., with Tennessee State University’s Family and Consumer Sciences.
Unexpectedly, as education and income increases, risky food-handling practices increase as well, said Sheryl C. Cates, Ph.D., at RTI International in Triangle Park, N.C. Interestingly enough, panelists couldn’t explain this phenomenon.
According to Godwin, many of us, well educated or not, think we know more than we do.Sources:

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
