Food safety relates to people’s health, society’s stability and national economy’s development. However, the current security situation of edible agricultural product is a concern, and it is urgent to solve this problem. This paper analyzes the current food safety situation and existing problems of edible agricultural products, theoretically discusses externalities and asymmetric information of edible agricultural products safety, and proposes the conception of constructing safety supervision system of edible agricultural product through learning from the advanced experience of food safety management and based on seamless organization theory.

Magnetoelastic (ME) biosensors were developed by immobilizing polyclonal antibody using Langmuir-Blodgett (LB) technique onto a magnetostrictive platform, which can offer wireless and remote detecting, a unique advantage over conventional sensor platforms. Due to the magnetoelastic nature of the amorphous magnetostrictive alloy, the sensor exhibits a physical resonance when it undergoes a time-varying magnetic field, a shift in resonance frequency occurs when its mass changes due to bacteria binding, and the bound bacterial cells were visibly confirmed by scanning electron microscopy (SEM) micrographs, then the density of bacteria bound on the biosensor was calculated. The specificity to detect different kinds of bacteria, including Salmonella species and non- Salmonella species was studied. The results show that the prepared polyclonal antibodybased biosensor shows excellent specificity to detect bacteria of Salmonella species, and especially prefers to bind Salmonella typhimurium, almost zero affinity for non- Salmonella species of Listeria monocytogenes.

E.coli isolates fromurine samples of patients suffering fromUrinary Tract Infections caused by E.coli was collected from various private diagnostic centers in Davangere, Karnataka, India. Isolates were cultured and maintained using specific media. Urea and Salinity tolerance of samples was checked by observing bacterial growth in artificial urine with varying urea and salt concentrations. Biochemical assays were carried out to identify virulence factors of Uropathogenic E.coli in samples showing high salt and urea tolerance.

Biosensors are analytical tools or systems consisting of an immobilized biological sensing material in close contact with a suitable transducer that convert the biochemical signals to a quantifiable electrical signal. Biosensors are now used in variety of disciplines, including medicine, food industry and environmental science. It is becoming increasingly important for researchers and scientists in these areas and other fields to have sound understanding of the different types of biosensors, which can be used, the principles behind them, and their advantages with their limitations. This review discusses the basic features of biosensors, types of biologicalmaterials used and details ofmost important types of biosensors currently used specifically in food industry. Online use of biosensor in processing of food materials is also discussed in detail with electronic control systems to make its use relevant as an emerging technology for food processors.
