Quality in Engure

Seafood Quality
Built Into Every Step

At SIA Unda in Engure, the Diplomats quality-control system connects raw-material selection, laboratory testing, food safety and documented release.

Begin with the principle

Quality philosophy

Quality philosophy, practised every day.

SIA Unda is the Latvian seafood manufacturer behind Diplomats. Seafood production began at the Engure site in 1907, and production knowledge has continued to develop in the same place.

Equipment, laboratory control and documented decisions support human judgement throughout production. Quality is a working discipline, not a final claim.

Laboratory testing

Laboratory testing behind every decision.

The SIA Unda laboratory has supported everyday seafood quality control since 1973. It analyses microbiological, physical and chemical indicators relevant to raw materials, production and finished products.

When a test cannot be completed in-house, it is assigned to a recognised external laboratory. The purpose is practical: reliable decisions, documented results and food-safety evidence for customers.

Certifications

Certifications with clear scope.

HACCP, IFS Food, MSC and FDA facility registration are described carefully. Current validity and scope must always be checked against the applicable certificate or programme.

01Implemented in 1998

HACCP

A systematic food-safety framework for identifying, controlling and documenting relevant hazards throughout production.

For customers: defined controls are built into the process, rather than left to final inspection.

02First certified in 2010

IFS Food

An audited food-safety and quality-management standard used by retailers and food businesses internationally.

For customers: an independent audit examines how the quality and food-safety system works in practice.

03Applicable certified products

MSC

Where MSC supports a sustainability claim, certification applies only to products and supply chains within the confirmed certification scope.

For customers: the mark is used only where the applicable product and chain of custody are covered.

04Facility registration

FDA

The facility maintains the registration required for applicable commercial activity involving products supplied to the United States.

For customers: US-market requirements are addressed within the relevant product and supply programme. Registration is not an FDA approval or endorsement.

Export quality for different market requirements.

Retail, private-label and foodservice customers bring different specifications, formats and regulatory requirements. The documented quality system lets each export programme be assessed without losing control of the product.

Quality through people

Quality through people.

Procedures create consistency. Experienced people still have to observe the material, recognise variation and make responsible decisions within those controls.

At Engure, production knowledge and laboratory evidence work together. That balance gives the quality system its practical value.
