until a dairy plant operator conducts another test and finds that milk from the
farm has a bacterial count not more than 750,000 per ml.
(g)
Division inspection; reinspection
fee. The division may inspect a dairy farm in response to any
bacterial count reported to the division under this section. If the division
inspects a dairy farm in response to a confirmatory bacterial count of more
than 750,000 per ml. under par. (f), the division shall charge a reinspection
fee under s.
ATCP 65.02(19). The division may not
charge a reinspection fee if the confirmatory bacterial count does not exceed
750,000 per ml., or if the division inspects more than 3 weeks after the
division receives the confirmatory bacterial count.
Note: Under s.
ATCP 65.920 the department will suspend a producer's grade
A farm permit if 3 of the last 5 bacterial counts reported to the department
under this section exceed the grade A standard of 100,000 per ml. under s. ATCP 65.70(2). The department will suspend the producer's grade A permit regardless
of whether any bacterial count exceeds the immediate response level of 750,000
per ml. under this section.
Note: Under s.
ATCP 65.920 the department may suspend a milk producer's
license if bacterial counts continue to exceed the grade B standard of 300,000
per ml. under s. ATCP 65.70(2). The department may suspend the producer's
license regardless of whether any bacterial count exceeds the immediate
response level of 750,000 per ml. under this section. If 2 of the last 4
bacterial counts reported to the department under this section exceed the grade
B standard of 300,000 per ml., the department will, at a minimum, send a
warning notice to the producer.
(h)
