What does mislabeled mean?
Mislabeled means incorrectly labeled or identified. The word is especially common in reports about products, containers, foods, medicines, files, photographs, and records that bear inaccurate names or descriptions. It often suggests a problem with packaging, labeling procedures, or record-keeping rather than a deliberate deception, although the context may imply a serious failure. As an adjective, “mislabeled” commonly appears before a noun, as in “mislabeled product” or “mislabeled container.” It can also be used as the past tense or past participle of “mislabel,” meaning to give something the wrong label. The word is useful because it identifies not merely an error but a mismatch between an item and the information used to identify it, which can have practical, commercial, or legal consequences.
Incorrectly labeled, identified, or described.
"The warehouse recalled the mislabeled packages after noticing that the nutrition information was wrong."
Common in product packaging, regulatory notices, records, and reports. It is also used as a participial adjective.
To label or identify something incorrectly.
"The technician mislabeled the samples before sending them to the laboratory."
Usually used in the past tense or past participle: “mislabeled,” “had mislabeled,” or “was mislabeled.”
A mislabeled item can be more than a naming mistake: it can mislead consumers, damage trust, or even create safety risks.

Etymology of mislabeled
The word was formed in English by combining the prefix “mis-,” meaning wrongly or incorrectly, with “label.” “Label” is the older element and comes through French from an Old French word associated with a band or ribbon. The combination follows ordinary English morphology, in which “mis-” forms words indicating error or incorrectness. The spelling varies between American and British English: “mislabeled” uses one “l,” while “mislabelled” uses two.
