The mere fact that operations preparatory to canning are physically
separated from the main canning operations of hermetically sealing and
sterilizing or pasteurizing would not be sufficient to remove them from
the scope of section 13(b)(4). Where preparatory operations such as the
steaming or shucking of oysters are performed in an establishment owned,
operated, or controlled by a canner of seafood as part of a process
consisting of continuous series of operations in which such products are
hermetically sealed in containers and sterilized or pasteurized, all
employees who perform any part of such series of operations on any
portion of such aquatic products for canning purposes are within the
scope of the term ``canning.''
