A person who is required by statutes administered by the Department of Agriculture, or by rules adopted pursuant to those statutes, to provide a suitable water supply, or plumbing or sewage disposal system shall not engage in the business of manufacturing, processing, selling, handling, or storing food at wholesale or retail unless the person’s water supply is satisfactory pursuant to rules adopted by the Department of Health, the person’s plumbing is satisfactory pursuant to rules adopted by the Department of Labor and Industry, and the person’s sewage disposal system satisfies the rules of the Pollution Control Agency. This section does not limit the commissioner’s ability to issue a food handler’s license when an investigation completed pursuant to section 28A.07 has determined the requirements of this section are not relevant and the applicant is considered fit to engage in business as described in the license application.
