If you’re a fan of almond milk because you have a dairy allergy, listen up. Before you reach for that carton in your fridge, you’re going to want to check out a few things on the packaging.

In the latest recall news, the company HP Hood LLC is now voluntarily recalling cartons of refrigerated Blue Diamond Vanilla Almond Breeze almond milk due to concerns that the product may contain milk, an allergen not listed on the label. While the product is completely safe to drink to those without a sensitivity to dairy, those with severe dairy allergies could run the risk of serious or life-threatening allergic reaction if they consume the recalled milk.

The recall applies to Vanilla Almond Breeze milk with a ‘use-by date’ of September 2, 2018. The cartons in question have one of the following codes stamped on their cartons:

USE BY: SEP 02 18 (07:36 – 20:48) H5 L1 51-4109
