I got on the hormel website and wrote a letter of complaint. They replied within 8 hours. That's amazing. I wish I would have saved the letter I sent them but I didn't think about doing so. Regardless I got a very appropriate reply from the company:
Thank you for reporting your experience with HORMEL(r) PILLOW PACK(r) Pepperoni. We can understand your disappointment with your package turning moldy so soon after opening. We do take numerous precautions to eliminate this type of situation from occurring.
