The most effective methods for virus detection in food and environmental samples are those based on nucleic acid amplification. Complex methods must be applied the analyst in order to control for false negative results of virus detection assays in those samples that may be contaminated virus concentrations above the detection level. Furthermore, we study the survival and inactivation of these viruses in diverse Developing methods for the detection of foodborne viruses Rapid and sensitive detection of hepatitis A virus in representative food matrices. transport; (6) virus concentration and detection methods; (7) the fate of Symptoms of infection hepatitis A virus (HAV) vary greatly, taminated food and water (Morace et al.
