ISO 22000 Certification in Nuts Processing: What It Means for Buyers

ISO 22000:2018 is the international standard for food safety management systems (FSMS), and for buyers of processed nuts — whether almonds, cashew, walnut, pistachio, or almond oil — supplier certification to ISO 22000 represents a robust baseline of food safety assurance. But understanding what ISO 22000 actually requires, how it relates to other standards like HACCP and FSSC 22000, and what practical value it delivers for your supply chain risk management requires more than recognising the logo on a supplier certificate. This guide explains ISO 22000 in practical terms for nuts procurement professionals.

What ISO 22000:2018 Requires

ISO 22000:2018 is a risk-based, process-oriented food safety management system standard built around three core components. HACCP (Hazard Analysis and Critical Control Points) is the scientific methodology for identifying food safety hazards in the production process — biological (microbial contamination), chemical (pesticides, mycotoxins, allergens), and physical (foreign material) — and establishing and validating control measures at critical points in the process where these hazards must be prevented, eliminated, or reduced to acceptable levels. PRPs (Prerequisite Programs) address the foundational food safety infrastructure — facility hygiene, pest control, water quality, maintenance, allergen management, staff training — that must be in place before HACCP is applied. Management System requirements bring the ISO management system framework (leadership commitment, documented procedures, internal audit, management review, continual improvement) to the food safety function.

ISO 22000 vs FSSC 22000 vs BRCGS

ISO 22000 is often discussed alongside FSSC 22000 and BRCGS (formerly BRC Global Standard for Food Safety) — the three most widely recognised food safety management system standards in global trade. FSSC 22000 is built on ISO 22000 with additional sector-specific PRPs from PAS 220 (food manufacturing) and FSSC-specific requirements — it is recognised by the Global Food Safety Initiative (GFSI), making it the preferred standard for many global food manufacturers who require GFSI-benchmarked supplier certifications. BRCGS is a UK-origin proprietary standard also recognised by GFSI, widely specified by major UK and European retailers and food manufacturers in their supplier approval requirements. For buyers sourcing nuts for supply into global FMCG food brands, FSSC 22000 or BRCGS certification from a nuts supplier will typically meet the highest supplier approval requirements. ISO 22000 certification (without FSSC add-on) is appropriate for buyers with robust internal due diligence processes and direct technical supplier relationships.

What Certification Does Not Guarantee

A critical and often misunderstood aspect of food safety certification is what it does and does not assure. ISO 22000 certification from a UKAS or equivalent-accredited certification body confirms that the supplier’s food safety management system meets the requirements of the standard at the time of the last certification or surveillance audit. It does not guarantee that any specific batch of product meets quality or food safety specifications — product quality is assured through product testing and specification compliance, not system certification. For nuts procurement, ISO 22000 certification should therefore be treated as a necessary but not sufficient condition for supplier approval. It should be complemented by: incoming inspection and/or product testing (aflatoxin, pesticide, microbiological) at receiving; review of COA from independent laboratories on each shipment; and periodic supplier audits or audit report review.

Cambay Industries’ Food Safety Programme

Cambay Industries operates an ISO 22000:2018 certified food safety management system across all nuts processing categories including almonds, cashew kernels, walnuts, pistachios, and almond oil. Our HACCP plans cover specific hazard profiles for each nut species — including aflatoxin CCPs for nuts from aflatoxin-susceptible origins, pesticide incoming material verification for all lots, metal detection CCPs in the packing process, and allergen management controls across shared processing lines. Annual third-party surveillance audits and full re-certification every three years are conducted by an accredited certification body. Buyers can request certificate copies and audit summary reports as part of the supplier qualification process. Contact our nuts procurement team to initiate a supplier qualification review.
