It depends if you are using a parent cache.

If you are getting FTP objects from your parent, then there is
no way for *your* squid to detect an aborted transfer from the
parent (unless the FTP server supports the SIZE command and the
HTTP reply has a content-length header).

But if you don't use a parent cache, then Squid will detect
aborted FTP transfers between Squid and ftpget, and it will
purge the aborted objects from the cache.
