Something I notice about this news article is it refers to the "California plant" and "Setton" (the name of the company) as making decisions. No, it was one or more human beings who made this decision.

FRESNO, Calif. - Food safety inspectors say a California plant at the center of a salmonella scare knew some of its pistachios were tainted but continued shipping nuts for another six months.
The Food and Drug Administration issued a sweeping national warning in March for consumers to avoid eating pistachios after concerns surfaced about nuts from Setton Pistachio of Terra Bella, Inc.
In an inspection report released this week, FDA officials said Setton first got results in October showing some of its roasted nuts tested positive for salmonella. But, officials say, it didn't make proper adjustments to its processing procedures and kept shipping out nuts.
