The U.S. Department
of Agriculture (USDA) Animal and Plant Health Inspection Service's Centers
for Epidemiology and Animal Health (CEAH), in conjunction with the USDA
Agricultural Marketing Service (AMS) and the National Mastitis Council
(NMC) Milk Quality Monitoring Committee, monitor milk quality in the
U.S. using bulk tank somatic cell count (BTSCC) data provided by four
of the nation's 10 Federal Milk Marketing Orders (FMOs).
the producer shipment BTSCC was 277,000 in 2009; 294,000 in 2008; 298,000
in 2007; and 293,000 in both 2006 and 2005.
Evaluating BTSCC Levels
More than 99% of the milk and 98% of the shipments monitored in these FMOs during 2010 met the current Pasteurized Milk Ordinance SCC federal regulatory limit of 750,000. Of the 31,912 producers, 91.2% shipped milk with BTSCC below 750,000 during all months monitored.
In 2010, during all monitored months, 89.5% of the milk would have met a goal of 400,000 SCC (which is the current European Union SCC limit); but only 50.7% of the producers would have done so.
Monthly monitoring continues to show that BTSCC peak during the summer months (July - September). In 2010, monthly milk-weighted BTSCCs were highest in August (262,000) and lowest in December (197,000).
