Premium Standard Farms (PSF), the nation's second largest pork producer, has achieved ISO 14001 certification for the comprehensive environmental management system (EMS) recently installed on its North Carolina farms.

ISO 14001 is a well-known environmental management standard that is published by the Geneva-based International Organization for Standardization.

The achievement of ISO 14001 certification has been a goal of the North Carolina operations since PSF began work on the creation of an EMS for its company farms in the spring of 2001, the Kansas City, MO-based company says.

Elements of the environmental certification include pollution prevention, regulatory compliance and monitoring plans and commitments to continual improvement. A regular, independent audit must also be maintained.

PSF plans to extend the EMS program to its other farming and plant operations.
