<p>The invention provides a process and anal seal for sealing the anus of the carcass (10) of a slaughtered animal. The anal seal includes a plug (15) for insertion through the anus so that tissues (11) contract behind the plug, a clamp (20) movable towards the plug to clamp the tissues behind, and retaining means (40) to hold the clamp in its clamping position. The plug (15) is conical and has a back end (17) so that the clamp which is in the shape of a clamping disc (22) clamps against periphery (18) of the back end of the plug. The clamp (15) can slide on a stem (32) extending from the back end of the plug. The retaining means (40) can comprise biasing means (48) or a latch (41) to hold the clamp in its clamping position. An applicator tool (60) can mount the anal seal during insertion of the plug into the rectum and move the clamp from a retracted position to its operative clamping position.</p> |
