One of the common uses is in Grinders and Stuffers to displace water from causing grinder plate and other steel parts from rusting and to lube the stuffer canister and O-ring for smooth operation. All those are direct food contact surfaces. The CRC brand has a NSF H1 code recommending limited contact. I can't find the NSF code for the LEM spray. Since a little goes a long way, I don't know if it represents that much of an issue and even using the slicer weekly there is probably more of a problem breathing the propellant than eating a tiny bit of silicone. But I am not a Toxicologist and I didn't sleep in a Holiday-Inn Express last night... In any event that spray is useful for grinders and stuffers, not to mention if sprayed in hard to reach areas of the slicer is an effective food release coating for easier cleaning and water displacement. Below is info on how members use it. If you are worried, you may have some luck with spraying the blade surface with PAM or rubbing on a thin coating of Food Grade Mineral Oil, found in the Pharmacy isle by the laxatives. Don't worry it is only a laxative in spoonful quantities...JJ
NSF Category Code: H1 This product is acceptable as a lubricant with incidental food contact for use in official establishments operating under the Federal Meat and Poultry Products Inspection Program. Such compounds may be used on food processing equipment as a protective anti-rust film, as a release agent on gaskets or seals of tank closures, and as a lubricant for machine parts and equipment in locations in which there is potential exposure of lubricated part to food. The amount used should be the minimum required to accomplish the desired technical effect on the equipment. If used as an anti-rust film, the compound must be removed from the equipment surface by washing or wiping, as required to leave the surface effectively free of any substance which could be transferred to food being processed. The final granting of authorization for the proposed use of such compound is the responsibility of the Inspector-In Charge of the official plant.
