There has been a sharp decline in the incidence and extent of dating ordinances in the past decade. Six areas now have dating ordinances compared with 21 in 1957. Per cent of the U. S. population residing in areas where dating of milk is required declined from 15 to 9% from 1957 to 1969.
No area has adopted dating regulations since 1957. Furthermore, enforcement of dating regulations is prohibited by state legislation in Illinois, Ohio, Connecticut, and Virginia.
Four areas which have retained dating ordinances have increased the time period allowable between time of pasteurization and sale of milk to consumers. Two jurisdictions do not specify a time limitation between pasteurization and sale of milk.
Expiration dating is required in New York City, Baltimore and Jefferson County (incl. Birmingham), Ala. Pasteurization dating is required in the State of New Jersey, St. Louis, and Suburban Philadelphia.
Adoption of the U. S. Public Health Service Grade “A” Pasteurized Milk Ordinance by many states appears to be the dominant reason for removal of dating ordinances by areas that formerly required dating.
