Article 6 Ear tags and tattoos
England, Wales and Scotland
An ear tag must be—
easy to read during the pig’s lifetime;
made of either metal or plastic or a combination of metal and plastic;
tamper-resistant;
incapable of re-use;
sufficiently heat-resistant that neither the ear tag nor the information printed or stamped on it can be damaged by the processing of the carcase following slaughter; and
designed to remain attached to the pig without harming it.
A tattoo must be applied either by tattoo forceps, in which case it must be on an ear, or by slap-marking equipment, in which case it must be on each shoulder and must, in either case, be easy to read.
As an alternative to applying a tattoo by the methods referred to in paragraph (2) a keeper may apply a tattoo to each shoulder by means of equipment which uses compressed air to drive the tattooing pins into the skin of the pig provided the tattoo is easy to read.
A keeper may mark a pig with any further information, or add further information to the ear tag or tattoo provided that the further information is clearly distinguished from the information required under this Order.
