What the classes mean

The FDA sorts every recall into one of three classes. The class is the whole story. It is also the part people skip.

ClassWhat the FDA is saying
Class IThere is a reasonable probability that using this will cause serious harm or death.
Class IIIt may cause temporary or reversible harm. Serious harm is unlikely.
Class IIIIt breaks a rule but is unlikely to hurt anyone. Often a labelling fault.

Class II is the bulk of every list here. That matters. A long list of Class II says something different from one Class I.

Checking whether it affects you

The lot or code number is what matters. Not the product name. A recall covers specific lots. Yours may not be one of them.

Check the code on your package against the report. The FDA keeps the current list at fda.gov/safety/recalls.

Read these counts with three things in mind

A firm with more recalls usually makes more products. A contract packer runs hundreds of lines. It will out-recall a company with one product whatever either does. This is not a safety ranking.

Most recalls here are voluntary. A firm found its own fault and pulled the stock. That is the system working. It lands in this database looking the same as a recall the FDA had to push for.

Terminated means the FDA considers the recall finished. It is not a verdict. It does not mean anyone was harmed.
