56 | March - April 2014 | dance with ISO 12100-2010. Lubricants are classified in accordance with ISO 6743-99:2002 and are deemed safe for product or incidental product contact by any of the following: the Food and Agriculture Organization of the United Nations, the World Health Organization, the European Parliament and Council Directive 95/2/EC, and the U.S. Code of Federal Regulations (CFR) 21, Part 178.3570. All of this falls under the larger umbrella of the Hazard Analysis and Critical Control Point (HACCP) system, which includes several different applicable standards such as the ISO 22000 series covering food-safety management. Sadly, there is not much over- sight in this area, and compliance is voluntary for the most part. It is promising that several nations are working together to develop policies on food quality, labeling and recall processes. The future of food-grade lubricants appears bright. As with most anything, education is critical. Currently, there is a large volume of conflicting and confusing information out there. Hope- fully, this article will help to dispel a few of these myths and clear up some of the confusion.

Contact Loren at BACk PAGe BAsICs 56% of lubrication professionals use food-grade lubricants at their plant, based on a recent poll at H1 — Lubricants used in applications where they might touch food, such as equipment over a food line. H2 — Lubricants used in locations where there is no possibility that the lubricant or lubricated surface contacts food, e.g., equipment under a food line. Standard industrial lubricants may qualify as H2 lubricants as long as they do not include heavy metals such as detergent and anti-wear/ extreme-pressure additives or compounds identified as carcinogens, mutagens, teratogens and mineral acids. H3 — Water-soluble and typically edible lubricants used to control rust. An example would be a meat hook or a trolley. P1 — Lubricants used in accordance with the USDA's letter of acceptance and not in a food or beverage processing plant. NSF Food-grade Lubricant Classifications
