FACTS NOT FANTASY.

There is no FDA limit for feces or fecal matter in USP-grade mineral oil, simply because zero contamination is permitted.

Because USP (United States Pharmacopeia) mineral oil is a pharmaceutical-grade product regulated as a drug for internal and topical use, it must undergo intense refining to be completely free of toxic impurities, aromatics, heavy metals, and biological or organic filth. Unlike certain agricultural food commodities where the FDA permits tiny amounts of "unavoidable defects" (like insect parts or rodent hairs), pharmaceutical products must adhere to stringent sterility and purity standards. [1, 2, 3]

The FDA and the USP strictly regulate mineral oil through the following parameters: [1, 2, 3]

• Pharmaceutical Use: The FDA regulates mineral oil as an OTC lubricant laxative and skin protectant under 21 CFR. It must meet the rigorous purity thresholds of the USP monograph for things like acidity, color, and polycyclic aromatic hydrocarbons. [1, 2, 3]

• Food/Indirect Use: The FDA permits a maximum of 10 ppm of white mineral oil as incidental contamination in food contact surfaces (21 CFR 172.878). [1]

• Microbial Limits: USP standards for non-sterile drugs (like mineral oil) require that the product must test free of objectionable microorganisms, which strictly precludes the presence of raw fecal matter. [1]

For detailed information on official compliance criteria, you can review the FDA Food Defect Levels Handbook or the U.S. Pharmacopeia for finished drug monographs. [1, 2, 3]
