Earl Mitchell, a Nebraska inmate, appeals the District Court’s 1 adverse grant of summary judgment in his 42 U.S.C. § 1983 action in which he claimed that certain Hall County Corrections Department employees exposed him to deplorable cell conditions and used excessive force. After de novo review, see Buckley v. Rogerson, 133 F.3d 1125, 1126 (8th Cir. 1998), we agree with the District Court that defendants were entitled to qualified immunity on the unsanitary-conditions claim, see id. at 1128 (explaining that government officials have qualified immunity from suit unless their actions violate clearly established statutory or constitutional rights of which reasonable person would have known); Whitnack v. Douglas County, 16 F.3d 954, 957-58 (8th Cir. 1994). We conclude that the force Mitchell alleged was used did not rise to the level of a constitutional violation. See Jones v. Shields, 207 F.3d 491, 494-95, 497 (8th Cir. 2000).

Accordingly, we affirm. See 8th Cir. R. 47B. We deny Mitchell’s motion to strike portions of appellees’ brief.
