popa: So to understand your point, if a kosher establishment finds out (after the fact) that for the past 3 months their employees were cooking their bacon in the oven they prepared their customers food…
a) nothing to worry about the past, as they’ve strictly been following all halachic kashrus requirements to maintain a kosher food establishment. Customers need not be notified nor must all their customers replace/re-kasher their utensils used with the food from the past 3 months, as all kashrus requirements were strictly followed.
b) nothing to worry about the future and no need to change any practices, as they’ve always been following all kashrus laws until now, as it is. And assuming all the bacon offending employees have since quit, there is no need to treat the new non-Jewish employees any differently than the previous bacon-baking ones, as all kashrus laws were always followed from the get-go.
l’m assuming I’m still misunderstanding you, and my above two conclusions based upon my understanding of your stated guidelines are incorrect. Please correct my understanding and point out where, what, and why the above two points aren’t the natural conclusion of your points.
Thanks
