What is Hygienic Design?
Hygienic design is the practice of engineering facilities, equipment, and processes to minimize contamination risk, support effective cleaning and sanitation, and maintain regulatory compliance. Hygienic design involves engineering every aspect of food production—from facility layout to equipment—to reduce contamination risks. A key principle: if you can’t see it, you can’t clean it. This approach ensures that inspections, swabbing, and sanitation are effective.
When to Consider Hygienic Design
Hygienic design should be carefully evaluated whenever new or used equipment is being purchased, ideally before signing any contracts, as well as anytime systems are modified, such as changes to piping or walls, since improper alterations can introduce contamination risks.
Common Mistakes
Common mistakes in hygienic design include choosing unverified vendors or manufacturers, allowing welding or modifications to be performed by unqualified personnel, and failing to recognize that issues stemming from poor hygienic design often do not appear until long after implementation.
Cost Benefits of Hygienic Design
While initial investments may be higher, hygienic design prevents costly recalls, extended sanitation times, and quality issues. For every $1 invested in prevention, companies can save $7–$10 in downstream costs.
Auditor Expectations
Auditors expect documented evidence of hygienic design practices, including:
- Review records and checklists.
- Contracts and invoices for equipment.
- Maintenance work orders.
- Interviews with personnel and observation of cleaning procedures.
Hygienic Design Checklist
Following a checklist aligned with SQF and 3-A Sanitary Standards Inc. (3-A SSI) helps ensure all equipment meets hygienic standards before purchase.
