I saw this October 1, 2013 memo from Audrey Rowe
http://www.usda.gov/wps/portal/usda/usdahome?contentidonly=true&contentid=shutdown_procedures.html
but not the OP’s October 11, 2013 memo on the USDA website.
From Zerohedge:
Foodstamp Program Shutdown Imminent?

But the website hasn’t been updated at all.
