Meat Industry Essentials - Cleaning & Sanitising

Main ideas / lessons conveyed

• Cleaning and sanitizing programs are essential for food safety in meat processing to ensure products are safe for consumers, families, and customers.
• The goal is to remove or destroy contamination:
  • Cleaning removes contamination (solids/material that can contaminate products or feed bacteria).
  • Sanitizing kills microorganisms (bacteria) using hot water or chemicals.
• Contamination must be prevented during and after production through planned procedures and hygiene practices.
• Effective sanitation supports regulation compliance and product quality, while also improving the workplace environment and safety.

Types of contamination identified

1. Physical contamination

   • Examples: rail dust, grease, jewelry pieces, plastic, boning hooks

2. Chemical contamination

   • Examples: cleaning chemicals applied wrongly or left behind
   • How it happens: work benches not washed off properly; chemicals applied incorrectly

3. Microbiological contamination

   • Examples: bacteria introduced from hide, workers, or processing equipment
   • Key conditions for bacterial growth mentioned: food/moisture, time, temperature
   • Impacts: can make consumers sick and shorten shelf life

Key sources/causes of contamination

• People
• Plant (environment/surfaces)
• Equipment
• Livestock

Difference between “cleaning” and “sanitizing” (conceptual framework)

• Cleaning

  • Removes solid material and residues (e.g., dirt, fat, blood, scraps)
  • Reduces risk of food poisoning and meets government requirements
  • Improves workplace conditions

• Sanitizing

  • Destroys microorganisms using hot water or chemicals
  • Kills bacteria that remain after cleaning

---

Materials removed by cleaning (two categories)

• Water-soluble material (e.g., dirt that dissolves in water)
• Water-insoluble material (e.g., fat, requires detergent)

Methodology / instructions presented: housekeeping + cleaning/sanitizing process

A) Good housekeeping practices (during production)

• Routinely remove:
  • fat
  • meat scraps
  • blood
• Keep production areas free of waste, because fat/meat/blood provide food for bacteria.
• Keep product area as dry as possible to reduce contamination likelihood.
• Prefer dry cleaning during production (“cleaning away fat, meat, blood, or waste without using water” when needed).
• Limit hose use, especially when carcasses/meat are exposed:
  • Hose water can splash contamination from walls/floors onto product.
  • Hosing also adds moisture, which helps bacteria grow.
• Ensure the work area has:
  • no excess waste/rubbish
  • no meat scraps on floors (to prevent slips/trips)

B) Post-production cleaning and sanitizing plan (after production stops)

• Follow a plan and standard operating procedures (SOPs)/workplace instructions that specify exactly what to do.
• Safety requirements while cleaning:
  • Wear the correct PPE
  • Be careful with hot water hoses and chemicals
  • Follow tagging and lockout procedures for cleared machinery

C) Six-step cleaning plan (described in the subtitles)

1. Dry clean Remove fat, meat, blood, and waste without using water

2. Cold water wash Wash away water-soluble dirt and blood

3. Manual scrub With combined detergents/sanitizers after the spray step

4. Apply detergents + sanitizers and allow soaking

   • Surfaces/equipment are sprayed with combined detergent/sanitizer
   • Allow cleaners to soak

5. Hot water rinse Rinse after scrubbing

6. Final inspection Inspect the plant to confirm it is adequately cleaned/sanitized

Note: The subtitle describes these steps in sequence as “dry clean, cold water wash, apply to … detergents and sanitizers, manual scrub, hot water rinse, inspector and oil a dryclean,” but the overall intended process is staged removal → wash → chemical/sanitizer action → scrubbing → hot rinse → inspection.

D) Pre-operational hygiene check (before production begins)

• A QA officer performs a check before production:
  • plant should look, feel, and smell clean
• In larger/medium plants:
  • surfaces and equipment are routinely sampled/swapped to verify they are microbiologically clean

E) Sanitizing chemicals + detergent combined (important caution)

• Some sanitizing chemicals are combined with detergents and can be applied at the same time.
• Risk: these chemicals can contaminate meat products if mishandled.
• Instruction:
  • Always follow manufacturers’ directions and SOPs
  • Follow proper use and storage instructions

Overall purpose/outcomes emphasized

• Minimize risk of food poisoning
• Meet government regulations
• Improve work environment
• Produce good quality meat products
• Reduce contamination by preventing microbial growth conditions and removing residues early
