No person shall permit another to operate a steam-controlled retort used in the commercial canning industry for the sterilization of food products, unless the latter first obtains a permit from the department. The department may pass upon and determine the qualifications of the applicant with a view to the preservation of the public health.
Any permit granted is revocable by the department whenever in its judgment the public health requires such action.
