Food products are being recalled at an alarming rate due to contamination. The pathogenic stain of Escherichia coli is one of the most common culprit that causes food and water borne illnesses.
Millions of illnesses and more than 1,000 deaths every year in the U.S. are attributable to foodborne illness caused by known pathogens, according to the Centers for Disease Control and Prevention.
Food Poisoning Symptom Evaluation
Food poisoning is the infection caused due to consumption of contaminated food. Food contamination can happen at any time during handling of food, its preparation or storage.

‘If customized, the device could help detect wide range of pathogens beyond E.coli and thus prevent many illnesses and deaths related to food poisoning.’

Researchers have now developed a new nanosensor to rapidly detect the presence of E.coli in food and water and thereby prevent the illness related to it. The study appears in the journal ACS Infectious Diseases.
Conventional methods to screen food to find sickness-causing microbes can take as long as 24 hours, which is often too slow to efficiently catch tainted products before they hit store shelves. Faster methods exist, but have limitations.

Good barbecue, good company and good beer can make an unforgettable day. However, if you fail to cook your meat perfectly, chances are high to turn things upside down.
Magnetic resonance, for example, can detect extremely low levels of bacteria, but loses its effectiveness at higher bacteria concentrations. Fluorescence is the opposite. Tuhina Banerjee, Santimukul Santra and colleagues wanted to see if they could combine the two techniques to make a better detector.
The researchers developed a hybrid nanosensor incorporating magnetic resonance and fluorescence. Lab testing of milk showed the detector could sense varying concentrations of a pathogenic strain of E. coli known as O157:H7 in less than an hour.
They also used their sensor to analyze E. coli levels in untreated lake water, which serves as a source of household water in some developing areas. Additionally, the device could be customized to detect a wide range of pathogens beyond E. coli, the researchers say.
