South Carolina Code of Regulations
Chapter 5 - DEPARTMENT OF AGRICULTURE
Article 9 - MILK
Section 5-434 - Sample Containers

1. Composite samples must be put in approved, airtight, round bottles which must be clean, dry, and free from cracks or chips. The sample bottles must have sloped shoulders with the neck not less than 1 3/4 inch in diameter and fitted with a tight rubber stopper permanently attached to the bottle.

2. Composite milk sample bottles must be not less than 8 ounces in capacity and must be etched for proper identification. Each composite sample bottle must be clearly identified as to a patron's name or number.

3. It is recommended that plastic sample bags be used for the sampling of bulk deliveries although composite bottles meeting the specifications and requirements under 1 and 2 of this section may be used. If bottles are used they must be fitted with Mojonnier rubber closure M427 rather than a regular stopper. Plastic bags and bottles must be iced from the time they are picked up until arriving at the processing plant. When bottles are used they should be carried in a suitable rack that will keep them upright in ice water and a drain should be provided in the truck's sample compartment to prevent the accumulation of ice water.

4. Only a licensed sampler or tester shall properly mix single bulk tank samples from producers before adding the required amount to the composite sample bottle in the processing plant.
