Adulteration

When a food product contains an unsafe substance, was processed under unsanitary conditions, or otherwise violates FDA safety standards.

What It Means

Adulteration in the context of food safety refers to a food product that is deemed unsafe or substandard under the Federal Food, Drug, and Cosmetic Act (FD&C Act). Section 402 of the FD&C Act defines food as adulterated if it bears or contains any poisonous or deleterious substance that may render it injurious to health; if it contains any added poisonous or deleterious substance that is unsafe; if it consists in whole or in part of any filthy, putrid, or decomposed substance; if it has been prepared, packed, or held under insanitary conditions where it may have become contaminated; if it contains an unsafe food additive or color additive; or if it contains a new animal drug that is unsafe. Adulteration is one of the primary legal bases for FDA food recalls. A food does not need to have actually caused illness to be considered adulterated — the mere potential for harm or the presence of unsanitary conditions is sufficient. Economic adulteration, where a cheaper substitute is used to cut a more expensive ingredient (such as diluting honey with corn syrup or substituting lower-quality fish species), is also a form of adulteration. The FDA addresses adulteration through inspections, sampling, testing, warning letters, recalls, import alerts, and in serious cases, criminal prosecution.
