For laboratories aiming for excellence and ISO/IEC 17025 accreditation, verifying competence on complex matrices is a fundamental step. Natamycin (or Pimaricin, E235) is an essential antifungal preservative for the surface protection of certain cheeses. Its analysis in hard cheese is a niche challenge that requires robust methods and constant verification of analytical accuracy.
Recognizing this specific need, Test Veritas is pleased to reintroduce the Proficiency Test for Natamycin in hard cheese (non-slurry) in its 2026 program, scheduled for the October Round.
Participating in this interlaboratory circuit provides objective proof of your ability to correctly measure this residue, meeting the most stringent quality control requirements.
Optimize Verification: The Importance of Aflatoxin M1 for Dairy Safety
Considering the daily challenges faced by dairy laboratories, Test Veritas has created a strategic optimization opportunity for 2026: a Convenience Package that combines the analysis of Natamycin with that of Aflatoxin M1 in hard cheese (both scheduled for the October 2026 Round).
Aflatoxin M1 is a highly carcinogenic metabolite that can contaminate milk and its derivatives. Maximum contamination limits are strictly established at the European level (e.g., Regulation (EC) No 1881/2006), making this analysis not only crucial but mandatory for the protection of public health.
A PT for Aflatoxin M1 in hard cheese, accredited according to ISO/IEC 17043, ensures that your results are in line with international safety standards, an essential requirement for any laboratory operating under ISO/IEC 17025.
A Commitment to Excellence and Accreditation
Choosing PT schemes that support the ISO/IEC 17025 accreditation requirements is essential. This combined package provides you with two PTs for critical analytes in the dairy sector in a single solution, allowing you to strategically cover Natamycin analysis and leverage an accredited PT for Aflatoxin M1, optimizing costs and management.

OUR STRENGTHS
- For all the PTs belongs to the Progetto Trieste it is possible to submit 2 sets of results and evaluate them in the Final Report, thus, with one subscription, 2 laboratory technicians, or 2 different methodologies.
- The sample is ready for analysis, no reconstitution is needed.
- If you order several PTs belonging to the same round, you will only pay shipping costs once!
Find out about all the PTs planned for June by consulting our programme! - Test Veritas has more than 25 years of experience as PT provider.
