Persistence of the 2009 pandemic influenza A (H1N1) virus on N95 respirators.

abstract：:The development of resistance in foodborne pathogens to food preservation techniques is an issue of increasing concern, especially in minimally processed foods where safety relies on hurdle technology. In this context, mild heat can be used in combination with so-called nonthermal processes, such as high hydrostatic p...
