What Is cGMP?

cGMP (current Good Manufacturing Practice) refers to the FDA regulations that establish minimum requirements for the methods, facilities, and controls used in manufacturing, processing, and packing of food, dietary supplements, and pharmaceutical products, including requirements for processing equipment such as vibratory screeners. The "c" in cGMP stands for "current," emphasizing that manufacturers must use up-to-date technologies and systems rather than relying on outdated methods. cGMP regulations are codified in 21 CFR Parts 110/117 (food), 111 (dietary supplements), and 210/211 (pharmaceuticals).

For vibratory screening operations, cGMP touches every aspect of equipment selection, maintenance, and operation. Equipment must be constructed of materials that are non-toxic, non-reactive, non-absorptive, and suitable for the intended product contact. Surfaces must be smooth, free of pits and crevices, and designed to allow thorough cleaning. Maintenance must be documented. Operating procedures must prevent contamination. These requirements directly influence the choice of screener model, construction material, screen cloth specification, and maintenance protocols used in food, supplement, and pharmaceutical processing.

cGMP Requirements for Vibratory Screening Equipment

Why This Matters in Vibratory Screening

cGMP compliance is mandatory for food, supplement, and pharmaceutical manufacturers, and it directly determines what vibratory screening equipment and screens you can use.

• Material selection — cGMP requires product-contact materials to be suitable for the product being processed. For most food and all pharmaceutical applications, this means 304 or 316 stainless steel for the screener body, screen frames, and screen wire. Carbon steel or mild steel components are not acceptable for product-contact surfaces.
• Screen traceability — cGMP documentation requirements mean you need to track which screen is installed in which screener, when it was installed, when it was inspected, and when it was replaced. Material certificates from your screen supplier provide traceability from wire mill to installed screen.
• Cleaning validation — Screeners in cGMP facilities must be designed for effective cleaning between product changeovers to prevent cross-contamination. Pre-tensioned screens with sealed bonds eliminate a common cleaning challenge: product trapped between loose cloth and frame.
• Audit requirements — FDA inspections and third-party audits (SQF, BRC, FSSC 22000) evaluate screening equipment against cGMP standards. Non-compliant equipment — wrong materials, poor maintenance, missing documentation — can result in 483 observations, warning letters, or production shutdowns.

cGMP FAQs

What is cGMP?

cGMP stands for current Good Manufacturing Practice. These FDA regulations establish minimum requirements for manufacturing methods, facilities, and controls for food, dietary supplements, and pharmaceuticals. The "c" emphasizes using current, up-to-date technologies. For vibratory screeners, cGMP requires suitable construction materials, cleanable design, proper maintenance, and documented procedures.

What cGMP requirements apply to vibratory screeners?

cGMP requires vibratory screeners to be constructed of non-toxic, non-reactive materials (typically 304 or 316 stainless steel), designed for thorough cleaning, maintained to prevent contamination, and operated with documented procedures. Screen cloth must be inspected regularly and replaced when worn. Material certificates provide traceability documentation required by cGMP quality systems.
