High Quality Content by WIKIPEDIA articles! SSOP?s are generally documented steps that must be followed to ensure adequate cleaning of product contact and non-product surfaces. These cleaning procedures must be detailed enough to make certain that adulteration of product will not occur. All HACCP plans require SSOP?s to be documented and reviewed periodically to incorporate changes to the physical plant. This reviewing procedure can take on many forms, from annual formal reviews to random reviews, but any review should be done by ?responsible educated management?. As these procedures can make their way into the public record if there are serious failures, they might be looked at as public documents because they are required by the government. SSOP?s in conjunction with the Master Sanitation Schedule and Pre-Operational Inspection Program, form the entire Sanitation operational guidelines for food related processing and one of the primary backbones of all food industry HACCP plans.
