2. Products and Processing

2. 1 Processing Procedures

Warm up2

Warm Up

  • What stages go into making this?

Slaughter processes

Slaughter Processes

  • Three Stages:

    • Preslaughter handling, stunning, slaughter

  • Humane Slaughter Act: required throughout processing

Preslaughter handling

Preslaughter Handling

  • Major Concern

    • Especially in pork

  • Increased stress releases hormones and changes meat quality

  • Stress can be reduced by:

    • Not mixing groups of animals

    • Adequate ventilation

    • No overcrowding

    • No food 24-48 hours prior. Only water !



  • Restrained in a chute single file

  • Three methods

    • Electrical

      • Electricity passes through the brain

    • Mechanical

      • Pistol

    • Gasing

      • Carbon Dioxide



  • Normally suspended by hind leg

  • Bled out (exsanguination)

    • Sever carotid artery and jugular vein.

  • Process varies by species

Slaughter cattle

Slaughter: Cattle

  • Stunned mechanically

  • Feet removed

  • Hung by Achilles' tendon

  • Skinned mechanically

    • Salted and tanned for later use for leather

  • Head removed at the atlas joint

  • Evisceration (removal of insides)

    • kidney, pelvic, and heart fat left in grading.

  • Cold storage for 24 hours

Slaughter swine

Slaughter: Swine

  • Stunned electrically or by gas

  • Hung by back legs

  • Exsanguination

  • Skin left on!

    • Scalding tank (145 degrees) loosens scurf (hair etc)

    • Dehairing machine

  • Head removed

  • Evisceration

    • Intestines saved for natural casing

Slaughter poultry

Slaughter Poultry

Meat inspection

Meat Inspection

  • Antemortem (BEFORE)

    • IDs animals not fit for human consumption

    • 4D animals

      • Down, Disabled, Diseased, Dead

      • Removed and labeled condemned

      • “Suspect” animals removed

  • Postmortem (AFTER)

    • head, viscera, and carcasses

    • IDs whole carcasses, individual parts, or organs not safe for human consumption.

Inspection during processing

Inspection During Processing

  • Previously inspected meat is used in the preparation of processed meat products

  • Ingredients are added to processed meats.

  • Reinspection during processing assures safe ingredients are used in the manufacture of processed meat products (e.g., sausage and ham).

Industrial animals and environmental impact


  • Humane Society of the United States

  • Established in 1954, The HSUS seeks a humane and sustainable world for all animals—a world that will also benefit people.

  • Video:

Think about it further

Think about it further

  • Write a letter to a state official explaining the need for the HSUS. Cite an investigation and explain why the investigation was needed (in context of human safe food) Finally, write about why the government should be more supportive of the HSUS. What agency should support them and why?

    • You will need to research the various gov’t agencies (FBI, USDA, FDA, CDC) and include their missions as supportive evidence

      • Why do we need the HSUS?

      • DO we even need them?

      • Where should their reach end?

      • What should they be responsible for?

      • Who should help them ? (FBI? FDA? USDA?)

      • Why do you think these agencies are remaining partially separated from the HSUS?

Activity break3

Activity Break

  • Design a flow chart, cartoon, or other type of manual explaining the slaughtering process in either cattle, swine, or poultry

Which takes more steps

Which takes more steps?

Beef processing

Beef Processing

  • Whole sale cuts: Primal cuts

    • chuck, loin, rib and round

  • Retail cuts: what you buy at the store

    • most expensive usually come from the loin area

    • chops and steaks such as the T Bone

  • Trimming

    • are made into sausage or ground meat

Cuts of meat

Cuts of meat

Beef processing grading

Beef Processing: Grading

  • Meat in freezer is graded according to USDA standards

    • Performed by AMS (Ag Marketing Service)

    • federal meat grading was established in 1925

  • Grades (2 types): certifies class, quality and condition with uniform standards

    • are determined by the age of the animal amount of fat intermingled with the muscle

    • Quality: prediction of the eating quality (palatability)

    • Yield: indicate expected yield of edible meat

Grade levels

estimate of the percentage of boneless, closely trimmed retail cuts that come from the major lean primal cuts

1 over 52.3 % lean primal cuts

2 50 - 52.3%

3 47.7-50.0

4 45.4-47.7%

5 less than 45.4%

  • prime

  • choice

  • select

  • standard

  • commercial

  • utility

  • cutter

  • canner

Grading continued

Grading Continued…



Fat= Marbling

specks of white in meat

More specks= higher grade

Prime=highest level of marbling

Skinny animals are cheaper to grow therefore the meat is cheaper than heavier animals

  • maturity of the cartilage and bones

    • Cartilage -> bone

  • Inspecting rib cage and vertebrae for the degree of bone and cartilage hardening - ossification

  • Animals older than about 42 months cannot receive the highest two grades

    • Young=Tender

Safety during processing

Safety During Processing

  • Major Players

    • USDA : helps set standards

    • HACCP processes

      • A food safety and self-inspection system that highlights potentially hazardous foods and how they are handled in the food service environment.
