Company Expands Recall of Salads After Additional Listeria Found, but Limits Amount of Product Recalled

A California company is expanding a voluntary recall of single-serve salad bowls. The recall comes after the Canadian Food Inspection Agency (CFIA) informed the company that another random sample of their salad with a (5.5oz) with Best Before Date of Dec 29, 2018, so as" a precautionary measure, [the company] is recalling all products produced on the same day, same production line, as the one sample that tested positive by CFIA."  The last recall was issued after CFIA found Listeria on product produced with a Best Before Dec 14th, and the company recalled the product produced on that date.

So will this company just wait for CFIA to find more positives before expanding the recall again?  Having an agency found two product positive should be a clear indication that this company probably does not have Listeria under control.
