PENTA Engineering Group, LLC provides SARS-CoV-2 surface sampling services to help clients protect their customers and employees from the spread of coronavirus. As businesses in the United States begin to reopen their doors, their client bases grapple with lingering concerns over whether these public places are safe from the virus. There were no commercially available verification methods until recently, only specialized cleaning guidelines and best practices without any way to check that these efforts were proving successful. While available methods of cleanliness verification could determine whether bacteria and mold remained on surfaces following cleaning efforts — and conventional wisdom might dictate that the absence of bacteria or mold indicates the absence of viruses as well — many consumers do not consider this inference sufficient regarding the coronavirus pandemic.
