A removable self-centring magnetically-clampable food-inspection pipe apparatus comprising: a food-inspection pipe with a through-bore having a tubular pipe body through which the through-bore passes, and a first connector part at each end of the pipe body defining first seating surfaces; and second connector parts which each define second seating surfaces and on which each first connector part is respectively slidably demountably seatable, one of the first and/or second connector parts having at least in part a magnetically-attractable material, and the other of the corresponding first and/or second connector parts having a plurality of magnetic elements equi-angularly spaced about a bore axis of the pipe body, poles of consecutive magnetic elements being opposite to each other, so that, as the food-inspection pipe is introduced laterally to the bore axis, the first and second connector parts slidably engage and self-centre the food-inspection pipe. A food-inspection device is also provided in addition to a method of improving hygiene of a food-inspection device.
