<strong>Guidelines</strong> <strong>for</strong> <strong>humane</strong> <strong>h<strong>and</strong>ling</strong>, <strong>transport</strong> <strong>and</strong> <strong>slaughter</strong> <strong>of</strong> livestock<br />

The st<strong>and</strong>ard method <strong>for</strong> the bleeding <strong>of</strong> cattle is to open the<br />

skin at the neck between brisket <strong>and</strong> jaw through a 30-cm<br />

longitudinal cut. Then, <strong>for</strong> hygienic reasons, a clean knife should be<br />

used <strong>and</strong> inserted at a 45 ◦ angle (Fig. 75) in order to sever the jugular<br />

<strong>and</strong> carotid vessels.<br />

In pigs, a longitudinal bleeding stick is made into the chest to<br />

sever the deep vessels (Fig. 76).<br />

For all cuts, the jugular <strong>and</strong> carotid vessels should be<br />

completely severed. If all vessels are not cut, bleeding may be<br />

incomplete, causing excessive retention <strong>of</strong> blood in the tissue, which<br />

can result in early spoilage <strong>of</strong> meat.<br />

A minimum <strong>of</strong> delay is required between stunning <strong>and</strong><br />

bleeding <strong>for</strong> two reasons:<br />

a. A prolonged delay in bleeding may result in a level <strong>of</strong><br />

consciousness being regained particularly where animals<br />

have been stunned electrically. For example, poultry<br />

stunned electrically may regain consciousness within 1-3<br />

minutes. Generally, bleeding <strong>of</strong> poultry should<br />

commence within 15 seconds <strong>of</strong> stunning. For other<br />

livestock, the interval between stunning <strong>and</strong><br />

sticking/bleeding should also be kept very short. Periods<br />

<strong>of</strong> less than one minute are desirable (Fig. 77).<br />

b. Delayed bleeding will result in an increase <strong>of</strong> blood<br />

pressure, <strong>and</strong> blood vessels will rupture, causing muscle<br />

haemorrhage. This extra blood in the tissue will cause<br />

the meat to decompose more quickly, resulting in waste<br />

<strong>of</strong> meat.
