Iowa Code Title V. Agriculture [Chs. 159-215A] § 194.8. Unacceptable milk

1. Milk acceptable from the standpoint of organoleptic examination, containing no excessive extraneous matter and classified in excess of three hundred thousand for bacterial estimate, may be used in the processing and manufacturing of dairy products for human consumption for a period of seven consecutive days.

2. After a week another quality test must be performed on the producer's milk. If two of the last four consecutive bacterial counts exceed the class 2 standard, the department shall deliver, or require the purchaser to deliver, a written notice to the producer. An additional sample shall be taken at least three days after taking the previous sample, but within twenty-one days following delivery of the notice. The department shall immediately suspend the permit of the producer or immediately institute legal proceedings to restrain production if the class 2 standard is violated according to three of the last five bacterial counts.
