The procedure described permits comparison of polyelectrolytes for their ability to flocculate food solids and thus enable filtration for recovery of food-borne viruses.

One question that is well known to persons working with food virology, and especially noroviruses, is “How important are these viruses, actually?” Frequently you feel somewhat uneasy when you start to reply, talking about the “trivial illness” of gastroenteritis, continuing on to the economic impact caused by the huge number of cases, and fi nally ending up admitting that you really do not know...

The purpose of this study was to develop methods for detection and quantitation of food-borne virus. Samples (25 g) of cottage cheese, contaminated with various quantities of coxsackievirus type A9, comprised the model system. Two of the methods presented have at least a 50% probability of detecting virus at levels below 5 plaque-forming units/25-g sample. Noteworthy aspects of these methods in...
