Each local official issuing an order prohibiting the sale of milk shall ascertain the average daily quantity of milk produced by the cows or goats of each person affected by such order of prohibition, and the municipality wherein such sale is prohibited shall pay damages for the value of the milk which such person has been unable to sell because of such order, during the period of prohibition, upon proof that, at the time such order was issued, such milk was fit for such consumption and the premises where such milk was produced were free from contagious disease. Any person aggrieved by such order, in the event of failure to agree with the municipality as to the value of the milk produced during such period, may collect the value thereof from such municipality.
