Bacteriological Protection of Bel-Ray Food Grade Products

The antimicrobial or biocide is routinely used in waterbased metal-working fluids or coolants to control and kill a microorganism. Oil-based food grade lubricants are commonly used in the food processing industry in order to provide lubrication in bearings, gearboxes, pumps, hydraulic systems, agitators, etc. Although the lubricant is often provided inside a piece of machinery, which is generally isolated from the exterior environment, food processing equipment is often cleaned using a high pressure water stream. Over time, water from the cleaning operations tends to make its way into the machinery and contact the lubricant, forming a water and oil emulsion. Such water and oil emulsions become fertile grounds for growth of bacteria, yeast and molds. In general, the concern is that bacteria may metabolize the lubricants and result in the formation of deleterious metabolites.

As a leader in non-toxic lubrication technology, Bel-Ray Company provides a broad and comprehensive line of food grade products for the Food, Pharmaceutical, Beverage, Cosmetic, Personal Hygiene and other "clean" industries. No-Tox is a trademark of Bel-Ray Company, Inc. Each of the Bel-Ray Food Grade products are uniquely formulated with EPA registered and FDA approved antimicrobials. The antimicrobials used in Bel-Ray Food Grade products are not antiseptics or sterilizing agents. They do, however, effectively inhibit the growth of certain bacteria, yeast and mold, and control microbial proliferation in Bel-Ray Food Grade products.

In the US, the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) established a set of pesticide regulations. A pesticide is a substance or mixture of substances used to kill a pest. A pesticide may be a chemical substance, biological agent (such as a virus or bacteria), antimicrobial, disinfectant or device used against any pest. Pests include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms) and microbes that compete with humans for food, destroy property, spread or are a vector for disease or cause a nuisance. When FIFRA was first passed in 1947, it gave the United States Department of Agriculture (USDA) responsibility for regulating pesticides. In 1972, when FIFRA underwent a major revision, it transferred responsibility of pesticide regulation to the Environmental Protection Agency (EPA) and shifted emphasis to protection of the environment and public health.

FIFRA requires that any marketed pesticide must be registered with EPA. However, under Section 152.25 of FIFRA regulation, EPA gives some exemptions for FIFRA regulation. Known as the "Treated Articles Exemption," Section 152.25(a) provides an exemption from all requirements of FIFRA for qualifying articles or substances treated with, or containing a pesticide, if: (1) the incorporated pesticide is registered for use in or on the article or substance, and; (2) the sole purpose of the treatment is to protect the article or substance itself. Clearly, lubricants fall into the "treated article" category. Pesticides are incorporated into treated articles because of their ability to inhibit the growth of microorganisms, which may cause odors and inhibit the growth of mold and mildew. Because of this treatment, it is claimed that a fresher and more pleasing surface can be maintained.

In Europe, DIRECTIVE 98/8/EC (so called, Biocidal Products Directive or BPD) of February 16, 1998 concerning the placing of biocidal products on the market is the current regulation on pesticides. BPD regulation is similar to FIFRA regulation in the US. Lubricants do not fall under the scope of the BPD as long as they are not intended to have a biocidal effect on any material or machinery on which they are used.

In conclusion:

1. The antimicrobials used in food grade Bel-Ray products are for internal (product) use only. Bel-Ray Food Grade product does not kill "on contact" nor does it have antiseptic properties. The antimicrobials used in Bel-Ray Food Grade products keep bacteria, yeast and molds from growing in the lubricants and being transferred to food or machinery, particularly when water gets into machinery.

2. Bel-Ray Food Grade products are not intended to have such an effect (i.e. to destroy, deter, render harmless, prevent the action of, or otherwise exert a controlling effect on harmful organisms), but rather to be used as lubricants for the food industry machinery, they are not antiseptics or sterilizing agents themselves.

The following is a list of the strains of bacteria, yeast and mold against which the antimicrobials in Bel-Ray Food Grade products are efficacious.
