Except as provided in sub. (2)
, a municipality having a population of more than 5,000, according to the most recent population estimate made by the department of administration under s. 16.96
, shall enforce the provisions of this chapter within its jurisdiction. For this purpose, a municipality shall establish a municipal department of weights and measures. Each municipal department of weights and measures shall have such number of qualified sealers or inspectors as will ensure compliance with this chapter. Municipal sealers or inspectors shall have the same authority as sealers or inspectors of the department of agriculture, trade and consumer protection. The selection of municipal sealers or inspectors shall be from a list of applicants whose qualifications have been certified by the state or local civil service agency under the rules of the agency. The municipality shall procure and keep at all times a complete set of standards of weight and measure conforming to the state standards and shall submit the standards for certification at regular intervals as required by the department of agriculture, trade and consumer protection. The municipality shall keep a complete record of its work and annually shall file a report thereof with the department of agriculture, trade and consumer protection. The municipality may enact ordinances that regulate weights and measures and that are not in conflict with this chapter or the rules of the department of agriculture, trade and consumer protection. The municipality may assess fees that do not exceed the actual cost of its weights and measures program.
A municipality that is required to establish a department of weights and measures under sub. (1)
may contract with the department of agriculture, trade, and consumer protection to enforce the provisions of this chapter within the municipality's jurisdiction instead of establishing its own department if the department of agriculture, trade and consumer protection agrees to enter into such a contract. The department of agriculture, trade and consumer protection may charge the municipality fees sufficient to cover the department's costs under the contract. A municipality may recover an amount not to exceed the cost of these fees by assessing fees on the persons who receive services under the weights and measures program.
Enforcement authority; measurement center laboratory. 98.05(1)(1)
There is hereby conferred upon sealers and inspectors of weights and measures, police power; such sealers and inspectors shall be provided with suitable badges or insignia of authority and in the exercise of their functions shall exhibit the same, upon demand, to any person questioning their powers, and they are hereby empowered and authorized to make arrests, with or without formal warrant, of any persons violating any statute relating to weights and measures.
Sealers or inspectors may enter and go into or upon any structure or premises, and may stop any person or vehicle for the purpose of enforcing this chapter. They shall inspect and test any weights and measures or commodities which are sold or used commercially as often as necessary to secure compliance with this chapter, and may seize as evidence, or reject and mark or tag as “rejected" those which are incorrect. A representative sample may be used as the basis to determine whether any lot is incorrect.
Weights and measures and commodities that have been rejected may be confiscated and destroyed by a sealer or inspector if not corrected within 30 days or such longer period as the sealer or inspector may authorize, or if used or disposed of without the sealer's or inspector's written authorization.
Sealers or inspectors may seal or mark with appropriate devices such weights and measures as are found upon inspection and test to be in conformance with this chapter.
Establish and maintain a measurement center laboratory for the testing and calibration of weights and measures; and

Declaration of quantity. 98.07(1)(1)
No commodity which is marked, tagged or labeled, or for which a sign is displayed, with a selling price, shall be sold unless the weight, measure or count of the commodity is conspicuously declared on the commodity or its tag, label or sign, but a declaration of count is not required if the selling price is for a single unit, or a set or combination of commodities customarily sold to and understood by consumers as a single unit, or if the commodity is packaged prior to sale and the package contains 6 units or less which can be easily counted without opening the package.
No commodity shall be wrapped or its container made, formed or filled so as to mislead the purchaser; nor shall the qualifying term “when packed", or the terms “jumbo", “giant" or “full", or words of similar import that tend to mislead the purchaser as to the amount of the commodity, be used in connection with a declaration of quantity.
With respect to commodities packaged prior to sale, the department shall issue rules permitting reasonable variations from declared quantity which unavoidably occur in good packaging and distribution practices.

Composite samples shall consist of representative samples taken during a period not exceeding 16 consecutive days. The unused portion of tested samples shall be retained not less than 5 days after testing to enable retesting by the department.
All purchasers of milk or cream from the producer, when using such milk fat tests to determine the value of any milk or cream received or bought by such purchaser, shall, when paying for such milk or cream, include an itemized statement to each patron showing the daily number of pounds of milk delivered, the total amount of butterfat content or test, transportation costs, and other charges and deductions for the period of time for which payment is made; except that the daily weights need not be shown on such statement if weight slips are furnished daily to producers.
Whenever milk is sold under an agreement, express or implied, that the value of the milk shall be determined by its proportion of butter fat, the price to be paid shall be based on a 3.5 percent butter fat standard.
