Nestle is doing a voluntary recall of limited quantites of Nestle Nesquik. Please see the letter below from the Nesquik Team that contains UPC numbers and contact information. Those products that have been affected have a “Best if sold by” date of October 2014. Homeland issued a statement earlier that if you purchased this at their store you can return it there.

To our Nesquik consumer,
You may have seen in the news media recently that we have executed a voluntary recall of limited quantities of Nestlé NESQUIK® chocolate powder in the 10.9, 21.8 and 40.7 ounce canisters. We wanted to reach out to you, our loyal consumer and provide you with an update. We pride ourselves on delivering you the utmost quality in our Nesquik products, and the health and safety of our consumers is our top priority. The voluntary recall is limited to only specific production codes of NESQUIK Chocolate Powder. No other varieties of NESQUIK powder or NESQUIK Ready-to-drink are affected by this recall. We are asking that you please take a moment to check if your NESQUIK® Chocolate Powder carries the production codes we are recalling. To find this code, please look on the bottom of the canister, adjacent to the consumer expiration date. If you find NESQUIK Chocolate Powder, with any of the production codes listed below, here’s what to do: Contact us at (800) 628-7679. Our consumer experts will help you.

Everything we do on the Nesquik brand is aimed at making the best possible product for you and your family. We know that is what you expect from us, and we will continue working tirelessly to exceed your expectations.
Thank you again for your loyal support.
Sincerely, The Nesquik Brand Team
