I have been eating Costco's Caesar salad for a long time and never got sick. Check the recall numbers or call Costco. I think Costco would pull them right away if there had been any problem. You could always wash your lettuce too.
Sorry. I don't herd nothing about.
Looks like you are in the clear https://www.costco.com/recalls.html
The combination plays major roles
You should call the manufacturer of whatever product you bought if from. I'm sure Costco would give you a refund though.
