The beef you're eating for supper tonight (well one can hope right!!) has gone through a long process of getting from "gate to plate". For simplicity sake, I will give you an overview of how a steer goes through the stages of beef production. Steers are not the only animals used for human consumption, however they are the most common especially when you are talking about where your delicious premium cut of steak comes from.

| Cuts of Beef |
- Cattle (mostly steers and heifers, some cows, and few bulls) are received by truck or rail from a ranch, farm, or feedlot.
- Cattle are herded into holding pens.
- Cattle are stunned by applying an electric shock of 300 volts and 2 amps to the back of the head or a captive bolt pistol (a pneumatic or cartridge-fired captive bolt) to the front of the head. This renders the animals completely unconscious.
- Animals are hung upside down by both of their hind legs on the processing line.
- The carotid artery and jugular vein are severed with a knife, blood drains, causing complete death through exsanguination.
- The head and front and rear legs are removed. Prior to hide removal, care is taken to cut around the digestive tract to prevent fecal contamination later in the process.
- The hide/skin is removed by down pullers and side pullers. Hides can also be removed by laying the carcass on a cradle and skinning with a knife.
- The internal organs are removed and inspected for internal parasites and signs of disease. The viscera are separated for inspection from the heart and lungs, referred to as the "pluck." Livers are separated for inspection, tongues are dropped or removed from the head, and the head is sent down the line for inspection of the lymph nodes for signs of systemic disease.
- The carcase is inspected by a government inspector for safety. (This inspection is performed by the Canadian Food Inspection Agency.)
- Carcasess are subjected to intervention to reduce levels of bacteria. Common interventions are steam, hot water, and organic acids.
- Carcasses can be electrically stimulated to improve meat tenderness.
- Carcasses are chilled to prevent the growth of microorganisms and to reduce meat deterioration while the meat awaits distribution.
- The chilled carcass is broken down into primal cuts and subprimals for boxed meat unless customer specifies for intact sides of meat. Beef carcases are always split in half and then quartered.
- The remaining carcass may be further processed to extract any residual traces of meat, usually termed advanced meat recovery or mechanically separated meat, which may be used for human or animal consumption.
- Waste materials such as bone, lard or tallow, are sent to a rendering plant. Also, lard and tallow can be used for the production of biodiesel or heating oil.
- The wastewater, consisting of blood and fecal matter, generated by the slaughtering process is sent to a waste water treatment plant.
- The meat is transported to distribution centers that then distribute to retail markets.
