Therefore, the HACCP system is just the beginning, required by law, of an organization of oriented systems committed to global quality standards.

Not only has ESI’s manufactured, stored and transported products been in full compliance with the rules of the HACCP, but they also obtained the ISO 9001 Certification that allows for TOTAL QUALITY, from design, to production, to the MARKETING its products.

The simultaneous introduction of the HACCP and the ISO 9001 Quality System involves substantial synergy which effects global quality.
