Abstract: | This review critically evaluates different types of immunosensors proposed for rapid identification of Escherichia coli O157:H7. The methods are compared with approved USDA-FSIS standard procedures for determination of this pathogen in raw or ready-to-eat meat products. Major advantages and disadvantages for each method are highlighted. Our analysis suggests that application of immunosensors in the meat-processing industry may be limited to identification of uncontaminated samples after conventional selective enrichment in broth. Use for detection appears limited at the present time. |
