Are nitrile gloves food safe? What the 21 CFR food-contact listing means, and what nitrile is not for

When the manufacturer states the glove meets FDA 21 CFR Part 177 (177.2600 for nitrile rubber). PIP marks those gloves “21 CFR” in its product data and the product page shows it; a glove without the listing is not stated for food contact.

Ketones and chlorinated solvents: PIP’s permeation data shows acetone under 6 minutes and methylene chloride 2 to 3 minutes on its unsupported nitrile. No voltage rating and no cut rating on a disposable nitrile glove.

To some chemicals: PIP’s data shows more than 480 minutes against isopropyl alcohol and 50% sodium hydroxide, 413 minutes against gasoline on the 50-N160 series, and minutes against acetone. The chemical resistance chart guide explains the levels.

The food-service nitrile gloves on this page are 3 to 5 mil in the manufacturer’s data, most at 4 mil; thickness is a durability figure, not part of the food-contact rule.

The FDA banned powdered examination and surgeon’s gloves in 2017 (21 CFR 878.4460, 878.4480); the gloves on this page are powder-free as the manufacturer states.

Not in the standards. Color is a manufacturer’s choice; blue became common in food and medical work because it shows against food if a piece tears off, and black is sold for automotive and tattoo work. The food-contact listing (21 CFR 177.2600 in the US, the EU food-contact rule in Europe) is on the box and in the product data, not in the color.

Disposable nitrile gloves run from about 3 mil to 8 mil at the palm (a mil is a thousandth of an inch): 3 to 4 mil for food service and exam use, 5 to 6 mil for shop work, 8 mil for heavier industrial use. Thickness is printed on the box; a thicker glove lasts longer but has no chemical or cut rating unless its data states one.

Nitrile is a synthetic rubber (acrylonitrile-butadiene) and contains no natural rubber latex proteins; the manufacturer states its Ambi-dex nitrile gloves are latex-free.

Food handling when the glove carries a 21 CFR Part 177 listing, examination and cleanup work where a latex-free barrier is wanted, and incidental splash with chemicals the manufacturer’s chart supports (isopropyl alcohol and 50 percent sodium hydroxide hold more than 480 minutes in the data here). Not for ketones or chlorinated solvents, electrical work or cut hazards.

4 mil is the most common thickness among the food-service nitrile gloves on this page (3 to 5 mil in the manufacturers’ data). Thickness is a durability figure, not part of the food-contact rule; MCR Safety lists the thickness in mil, the length and the AQL grade (medical 0.0 to 1.5, industrial 1.6 to 4.0) on each disposable style.

For incidental splash with a chemical the glove’s chart supports, yes, and they are removed as soon as they are contaminated. Thin disposables show short breakthrough times for many solvents; for soaking or extended contact the chemical resistance chart guide explains how to read the manufacturer’s data.

Disposable (single use) gloves are not washed or decontaminated for reuse under 29 CFR 1910.1030(d)(3)(ix)(B), and the FDA Food Code change-out points apply in food work; a torn, punctured or contaminated glove is replaced at once. Reusable nitrile is a different, heavier glove with its own chart.
