If you identify a hazard requiring a preventive control, do not control the identified hazard, and rely on a subsequent commercial entity in the distribution supply chain to address the hazard, you need to make a written disclosure. However, the written disclosure cannot be used in lieu of implementing a preventive control if the food is not going to be subject to further commercial processing that will control the hazard(s). In other words, the written disclosure cannot be used with consumer-facing/retail products.
