31 Pa. Stat. § 700j-608
Milk dealers shall determine weight, measure and butterfat and appropriate milk component content of milk as provided in this act, or in rules, regulations or orders of the board pertaining thereto and consistent with this act. Payment for milk shall be made either upon the basis of weight, measure or butterfat or appropriate milk component content, or any combination thereof, as the rules, regulations or orders of the board may require.
Milk dealers buying or receiving milk from producers shall furnish to each producer or his agent a written statement showing the amount of milk delivered daily during the period for which payment is made, and, unless the board otherwise provides, the average butterfat or appropriate milk component tests of the milk delivered for such period. Such statement shall set forth such information as may be required by the board, shall be furnished periodically, at the time of payment prescribed by the board, and in no event less often than monthly: Provided, however, That a written statement of weights shall be given daily to the producer or his agent, upon written request of a majority of the producers, who deliver milk to any receiving station or plant receiving milk, each receiving station or plant to be considered separately, in lieu of such periodic statement of the amount of milk delivered, unless the board otherwise provides.
It shall be unlawful to use as the basis of payment for milk any amount or percentage of butterfat or appropriate milk components therein which has been ascertained from a sample containing milk that has been so treated as to cause it to test lower or higher than the milk from which it was taken.
It shall be unlawful for any person, including any milk dealer, to knowingly, fraudulently, or negligently weigh, measure, sample or test milk, or cause milk to be weighed, measured, sampled, or tested in such manner as to cause or tend to cause loss or injury to milk producers, stores or milk consumers, or to make any false or misleading statement with respect to the weight, measurement, sampling or testing of milk.
