The developing trend in aquafeed plants is to insure feed safety throughout the production process. A strategic path to accomplish this would be to assess and design the facility with attention to the following areas: raw materials and their storage, plant equipment design, processing or operating procedures, final product efficacy and the overall culture or day to day operation of the plant.
Hygienic design principles for aquafeed plants and the equipment should be designed to achieve a cleanable HACCP level. The equipment should be constructed of compatible materials with accessibility for cleaning and inspections with no material collection points or niches.
The way forward in aquafeed production safety is to strive to identify and validate critical control points in the process and operate on that basis. Avoid recontamination in downstream areas after the critical points and install a finished product testing procedure for validation.
