New Mexico Piñon Coffee announced in a press release that it was voluntarily recalling 154 boxes of its Dark Pinon Single Serve Cups, which have 10 pods per box. The recall was issued because of the “potential introduction of food coloring into the cups ,” which are compatible with Keurig machines, during brewing.

A clear seal of the lids on some pods was not applied properly, which can cause ink to run when in contact with hot water.

A coffee retailer has issued a recall for single-serve coffee cups sold at major retailers like Costco, Walmart and Target.
