"I need a bender inside me" sounds wrong...
Indeed, the food regs have changed a lot since I started my Food Technology BTEC in 1883.
You will be pleased to learn they have changed in this respect, at least:
The Regulations provide that the following parts of the carcase may not be used in the preparation of uncooked meat products: brains, feet, large and small intestine, lungs, oesophagus, rectum, spinal cord, spleen, stomach, testicles and udder.
However, the Regulations do allow intestines to be used to produce the skin for sausages and similar products. It is important to note that this exemption applies not just to products meeting the reserved description “sausage”. Intestines may also therefore be used to produce the casing for products such as haggis, black pudding etc.
