From my research (on states west of the Mississippi) all states have some kind of anti-hoarding laws on the books (usually only enforceable during a state of emergency). Two weeks' food was the magical number I kept running up against, probably the result of some federal study.
The only really weird one I remember (this has been a few years), was Hawaii, where a one week rule was enforceable in normal times (not in the actual legislation, but in committee notes attached):
128-28 Forfeitures. The forfeiture of any property unlawfully possessed, pursuant to paragraph (2) of section 128-8, may be adjudged upon conviction of the offender found to be unlawfully in possession of the same, where no person other than the offender is entitled to notice and hearing with respect to the forfeiture, or the forfeiture may be enforced by an appropriate civil proceeding brought in the name of the State. The district courts and circuit courts shall have concurrent jurisdiction of the civil proceedings. Any property forfeited as provided in this section may be ordered destroyed, or may be ordered delivered for public use to such agency as shall be designated by the governor or the governor's representative, or may be ordered sold, wholly or partially, for the account of the State. [L 1951, c 268, pt of 2; RL 1955, 359-25; HRS 128- 28; am imp L 1984, c 90, 1]"
Enjoy the paranoia, I know I have.
If your state or area is ever declared a "disaster" by the governer you are fully under the jurisdiction of the federal gubmint...and FEMA
