United States Standards. In the Federal Food and

Plain condensed milk is made in a similar manner, but 

 is not sterilized. It is usually marketed in ordinary milk 

 cans in the same general manner as fresh milk. It will 

 keep in good condition for from ten to thirty days, if kept at 

 a low temperature. It is intended for early consumption,
