No milk dealer, processor, subdealer or store, as defined in this act, shall buy milk from producers or others for sale, disposal, importation, transportation, storage or manufacture, or sell, transport, import, dispose of, store or distribute milk or otherwise engage in the milk business within this State, unless duly licensed as in this act provided, and it shall be unlawful for a milk dealer, processor, subdealer or store to buy milk from a milk dealer, processor, subdealer, or store who is unlicensed, or to sell to milk dealers, processors, subdealer or store in this State who is unlicensed, or in any way to deal in or handle milk which he may have reason to believe has previously been dealt in or handled in violation of the provisions of this act or any order, rule or regulation of the director promulgated pursuant thereto.
The licenses required by this act are for the purpose of correcting unfair, unjust, destructive and demoralizing practices in the milk industry in this State, and to prevent demoralization of agricultural interests engaged in the production of milk in this State. The licenses required by this act shall be in addition to any other license or permit required by any law of this State, or by any ordinance of a local board of health or other body exercising the powers thereof in any municipality of this State, and shall not be considered as such a license or certificate as is contemplated by section 40:52-1 of the Revised Statutes. When the department of health of the State of New Jersey or any local board of health shall refuse to license, suspend or revoke the right of a licensee to sell or distribute milk or cream in a particular municipality, the license granted by the director shall so far as said municipality is concerned be suspended or revoked for such time as such suspension or revocation shall be continued by said municipality.
