1. Announcement

The National Institute for Food Control is pleased to announce the production and supply of a new batch of microbiological reference strains, intended for use by testing laboratories in the fields of food, pharmaceuticals, and environmental analysis.

These reference strains are produced under strictly controlled processes to ensure purity, stability, and traceability, meeting the requirements for laboratory testing and quality assurance.

The use of microbiological reference strains plays a critical role in:

• Internal quality control of laboratories
• Method validation and verification
• Ensuring accuracy and reliability of analytical results
