La. Stat. tit. 3 § 641
Any person, firm, or corporation who shall engage in the business of purchasing milk from producers or co-operative associations for the purpose of manufacturing, pasteurizing, distributing milk or milk products shall, before carrying on business, furnish a bond or other security for the payment of all amounts to become due by them to the producers of milk or co-operative associations for milk sold by producers or co-operative associations. The bond shall be signed by a surety company authorized to do business in Louisiana. The bond or such other security as may be required shall be sufficient in amount to cover all amounts due the producers of milk or co-operative associations for two normal or customary pay periods, but not to exceed twenty-five days in total, based upon the average of the preceding six-month period of purchases from milk producers or co-operative associations, provided that the minimum bond or other security shall not be less than the amount sufficient to cover amounts due producers or co-operative associations for one week's purchases. The bond or other security shall be approved as to form, amount, and sufficiency by the commissioner of agriculture and forestry and shall be filed by him and retained in his office, subject to public inspection.
