Reviews on Food Safety

Abstract:
Food safety is an increasing concern. The desire for rapid, specific
methods for the detection of viable potential pathogens has grown into a
necessity. Microbial contamination of meat, fresh fruits, and vegetables
has become a mounting concern during the last decade due to emphasis
on their importance in a healthy diet and the recognition of new
foodborne pathogens such as Campylobacter jejuni, Escherichia coli
O157:H7, and Listeria monocytogenes. This paper presents an overview
of different commercial techniques for identification of bacteria such as:
III-nitride on Silicon Chips for detection of live bacteria, Optical
Biosensors, Piezoelectric-based acoustic wave devices, Electrochemical
Biosensors, Immunomagneic Technique, Polymerase chain reaction.
