Dipstick Assay

Utilizing Dipstick Assay to Detect Human Pathogens on Strawberries.

While we are enjoying fresh strawberries, we should always pay attention to food safety issue, such as food-borne pathogens. Dr. Fur-Chi Chen, an expert in food safety, is demonstrating the dipstick assay, which is simple and rapid, to detect human pathogens, such as Salmonella, Listeria, and E.coli, on strawberries. Please watch the video: Demonstration of Dipstick Assay.
