We had a guy at a previous job of mine (food service) who (almost certainly) didn't wear deodorant and it became an HR issue.
His roommate (who also worked with us) said he did shower.
Unless the person in question had a medical condition... I find this very hard to believe. There are a lot of cultures where people don't use deodorant but wash every day (and more if doing sports etc... And it's not an issue).
