Should blood centers routinely screen blood products for COVID-19 virus?

No, although RNA fragments of SARS-CoV-2 were detected in blood of symptomatic COVID-19 patients, this does not mean that the virus is viable/infectious. In general, respiratory viruses are not known to be transmitted by blood transfusion. Blood centers should have routine blood donor screening measures in place to prevent individuals with respiratory symptoms or fever from donating blood.

As precautionary measures, blood centers might encourage self-deferral of those with travel history to an COVID-19 affected country in the previous 14 days, or of those who have been diagnosed with COVID-19 or are close contact with a confirmed COVID-19 case.
