An adsorbent for toxic shock syndrome toxin-1 (TSST-1) comprising a compound which has a log P value of at least 2.50 wherein P is a partition coefficient in an octanol-water system and which is immobilized on a water-insoluble carrier; a method for removing TSST-1 body fluids by adsorption which comprises bringing a body fluid containing TSST-1 into contact with the adsorbent; an adsorber for TSST-1 comprising an adsorbent packed in a container having an inlet and an outlet for a body fluid and a means for preventing the adsorbent from flowing out of the container; and use of the adsorbent. TSST-1 in body fluids can be efficiently removed by the adsorbent.
