This week the FDA began invalidating food facility registration numbers that were not reviewed for the biennial registration period. Â If your registration lapsed, be sure to contact transitionus@willsonintl.044d949.netsolhost.com once a new number is obtained so our records can be updated. Â Willson International also offers the service of FDA Agency. Â Failure to register your food facility with the FDA will cause delays in shipment processing.
