   MEMORANDUM

Henry J. Prien, a former Idaho state prisoner, appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his serious medical needs in violation of the Eighth Amendment. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir.2004), and we affirm.

The district court properly granted summary judgment because Prien failed to raise a genuine issue of material fact as to whether prison medical staff were deliberately indifferent by failing to provide him with a special diet to accommodate his onion allergy and in treating his hand injury. See id. at 1057; see also id. at 1059-60 (a difference in opinion about the preferred course of medical treatment does not constitute an Eighth Amendment violation). Accordingly, because prison medical staff were not deliberately indifferent, defendant Warden Smith cannot be held liable as a supervisor. See Taylor v. List, 880 F.2d 1040, 1045 (9th Cir.1989). Moreover, defendant Johnston cannot be held liable because she was not the proximate cause of the alleged violations. See id. (“Liability under section 1983 arises only upon a showing of personal participation by the defendant.”).

Prien’s remaining contentions are unpersuasive.

AFFIRMED. 
      
       This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3.
