Darryl Moore, Louisiana prisoner no. 117655, appeals the dismissal, without prejudice, of his 42 U.S.C. § 1983 action in which he complains of a prison disciplinary sanction. We review the dismissal de novo and take a strict approach to the requirement that a prisoner exhaust administrative remedies. Days v. Johnson, 322 F.3d 863, 866 (5th Cir. 2003) (strict approach); Powe v. Ennis, 177 F.3d 393, 394 (5th Cir. 1999) (de novo review). Nothing in the record on appeal shows that Moore exhausted his administrative remedies prior to filing his action. See Wendell v. Asher, 162 F.3d 887, 890 (5th Cir. 1998); 42 U.S.C. § 1997e(a). The judgment of the district court is

AFFIRMED.
