La. Stat. tit. 56 § 437
Oysters which have been harvested from Louisiana waters may be sold for raw consumption within the state at all times during the year provided however, that during the time period from May first through October thirty-first each year, movement of such oysters from harvest to refrigeration shall take no more than five hours. Federal regulations which may prohibit the interstate transportation and sale of oysters which have not been post-harvest treated shall not apply to oysters harvested, sold, and consumed within the state of Louisiana. The Louisiana Department of Health shall promulgate rules pursuant to the Administrative Procedure Act to administer the provisions of this Section and the Department of Wildlife and Fisheries shall assist in the enforcement of such rules. Such rules shall allow up to five hours for the oysters to be transferred from harvest to refrigeration as provided in this Section.
