The permit is obtained by submitting an application along with a $25 fee to the Department of Agriculture. Department of Agriculture will inspect the equipment and premises before issuing the permit. The permit shall be issued for a period of one (1) year.
The permit stipulates that the garbage must to heated to a temperature of 212 degrees Fahrenheit (212°F) for 30 minutes before it can be fed to swine, recording thermometer charts must be maintained and stored properly and daily cooking records must be kept for a period of 90 days.
