Within the 11 contamination events when Uncooked products have been recognized given that the source from the viral contaminant, Original screening of that Uncooked product didn't detect virus. Only once the viral load was greater, via focus or biological amplification, was the virus detected from the raw material, and afterwards only in 3 situations (Fig. one).
