Food poisoning test kits for viruses like Rotavirus, Norovirus, Intestinal Adenovirus, Astrovirus, and Zaruvirus are crucial tools for detecting and preventing the spread of foodborne illnesses. These kits typically utilize molecular biology techniques such as polymerase chain reaction (PCR) or enzyme-linked immunosorbent assay (ELISA) to identify the presence of specific viral pathogens in food samples.
