WASHINGTON (AP) — U.S. manufacturing output declined in August for the first time in seven months, reflecting a sharp fall in production at auto plants that was due mainly to seasonal adjustment problems.

Output at manufacturing plants fell 0.4 percent in August after a 0.7 percent rise in July, the Federal Reserve reported Monday. Total industrial production was down 0.1 percent in August, also the first setback for the overall figure since January. Output was up in mining and utility production but these gains were not enough to offset the decline in manufacturing.
