To minimize the risk of contamination and cross-contamination, it is essential to: Response:

Question

Options

• AIncrease the speed of production
• BUse unqualified disinfectants
• CIgnore personnel flow patterns
• DImplement proper cleaning procedures

• A
  9% (2)
• B
  5% (1)
• C
  14% (3)
• D
  73% (16)

Explanation

Implementing proper cleaning procedures (D) is the cornerstone of contamination control because it physically removes and destroys microorganisms, residues, and potential cross-contaminants from surfaces, equipment, and environments - breaking the chain of contamination at its source.

Why the distractors are wrong:

• A (Increase production speed): Faster production shortcuts cleaning time and increases error rates, which raises contamination risk rather than reducing it.
• B (Use unqualified disinfectants): Disinfectants that aren't validated for the specific pathogens or surfaces present may fail entirely, creating a false sense of safety.
• C (Ignore personnel flow patterns): People are a primary vector for cross-contamination; ignoring flow patterns allows contaminants to travel from dirty to clean zones.

Memory tip: Think of the acronym CLEAN - Control contamination by Legitimate Effective Action Now. Proper cleaning procedures are the only active, validated intervention in the list; the other options all involve neglect or shortcuts that compound risk rather than reduce it.
