I got an email response from a Clif rep yesterday, quite nice:
Dear Emily,
We are glad that you contacted us with your refund request and recalled bar information. I am emailing to confirm that we have received and processed your request for a refund.
We will fulfill your request as soon as possible, but please allow several weeks due to processing and mailing.
We urge you to throw away any of our recalled products to ensure no one mistakenly eats them. We do not need the wrapper so please dispose of them properly. No other Clif Bar & Company products or flavors are included in this recall.
Thank you again for contacting us. You have my sincere apology for your inconvenience.
Sincerely,
Allison
