Kansas State University master's student Lance Noll has developed and validated a molecular assay that can detect and quantify major genes specific to E. coli O157.
Research presented at the Society for General Microbiology's annual meeting shows that the disease-causing E. coli O157:H7 interacts directly with plant cells, allowing it to anchor to the surface of a plant where it can multiply.
To combat food fraud, we need to identify which factors play a role in vulnerability of organisations and the food chain, according to Saskia van Ruth, the newly appointed Professor of Food Authenticity and Integrity at Wageningen University.
A new study may have cemented hospital food's bad reputation. The study found that more than 80% of raw chicken in hospitals was contaminated with an ESBL-producing E. coli strain which is resistant to antibiotics.
Non-destructive food quality testing could soon be a reality, thanks to researchers from the University of Western Australia. The technique is similar to using infrared thermometers to detect body temperature.
Spanish researchers have developed what they call an "electronic tongue" - an analysis system based on the human sense of taste that can distinguish between several brands of beer.
In response to increased demand for monitoring and labelling of genetically modified (GM) foods, scientists have developed a comprehensive method for detecting GM ingredients. It is claimed to be the first of its kind in the world.
Mocon's OX-TRAN Model 2/21 10x system accurately and repeatably measures barriers at levels 10 times lower than previous levels. The system measures films or packages at precise temperature and relative humidity conditions.
Recognising the need for a real-time biosensing system to detect pathogenic bacteria such as Salmonella, a team of researchers from Auburn University has come up with a system which includes a magnetoelastic biosensor.
The machine, designed by Purdue University researchers, reportedly concentrates foodborne Salmonella and other pathogens faster than conventional methods by using hollow, thread-like fibres that filter out the cells.
The majority of herbal products on the market contain ingredients not listed on the label, according to recent research from the University of Guelph.
Measurement company Agilent Technologies has announced the opening of its new Spectroscopy Technology Innovation Centre in Mulgrave, Victoria. The $25 million centre houses cutting-edge research and testing laboratories, as well as user demo and training facilities.
The OdourScan Model 2000 Electronic Nose uses a set of six tin oxide detectors that have different sensitivities to detect different odourants and gases. The response from one or multiple detectors can be used to detect and measure the odourants.
In recent years in China, illegal cooking oil incidents have led to serious food safety risks and negative social repercussions. The illegal cooking oils include the refined waste oil from restaurants, repeatedly used oil and waste animal fats. Because such cooking oils may contain toxic polymers, peroxide and so on, they can be dangerous to human health.
A new process for making a 3D microstructure that can be used to analyse cells could be useful in counterterrorism measures and water and food safety concerns.
