Every person, other than the producer, in selling eggs to a retailer, shall furnish to such retailer an invoice showing the exact grade or quality of such eggs according to the standards prescribed by the commissioner of agriculture and markets. If any of the eggs covered by the invoice have been in cold storage, as defined in article nineteen of this chapter, for more than thirty days, either within or without the state, the invoice, in addition to showing the grade or quality of such eggs, shall indicate the fact of such storage by the use of the words 'cold storage' or 'refrigerator.' A copy of such invoice shall be kept on file by the person selling and the retailer at their respective places of business for a period of sixty days, and shall be available and open for inspection at all reasonable times by the state department of agriculture and markets.
