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, determines 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 294,000 in 2008, 298,000 in 2007; 293,000
in both 2006 and 2005; and 296,000 in 2004.
750,000 vs 400,000
More than 99% of the milk and 98% of the shipments monitored in these FMOs during 2009 met the current Pasteurized Milk Ordinance SCC federal regulatory limit of 750,000. Of the 32,854 producers, 90.5% shipped milk with BTSCC below 750,000 during all of the months monitored.
In 2009, during all months monitored, 89% of the milk would have met a goal of less than 400,000 BTSCC, which is the current European Union SCC limit; but only 50% of the producers shipped milk with BTSCCs less than 400,000 during all monitored months.
Monthly monitoring continues to show that BTSCC peak during the summer months (July - September). In 2009, monthly milk-weighted BTSCCs were highest in August (254,000) and lowest in November (212,000).
