Today, USDA release its "Dairy Product" report: http://usda.mannlib.cornell.edu/usda/current/DairProd/DairProd-04-01-2010.pdf
The report shows cheese production up 1% over February 2009. Again, these are not precise measurements, however, there were a number of disruptive storm which, perhaps, sent more milk to the cheese vats.
Interestingly, MPC production was down. Rumor has it, the profit just isn't there - how odd. At the same time MPC imports for January, the latest month available, were also down.
