3. Hygiene meaning
Collins Dictionary:
Hygieneis the practice ofkeepingyourself and your
surroundings clean,especiallyin order
topreventillnessor thespreadof diseases.
Cambridge Dictionary:
Thedegreeto whichpeoplekeepthemselves
ortheirenvironmentclean,especiallytoprevent

What will causes the disease??

4. Definition
Contamination:
The undesired introduction of impurities of a
chemicalor microbiological nature, or of foreign
matter, into or onto a raw material, intermediate, or
API during production, sampling, packaging or
repackaging, storage or transport.
Cross-Contamination
Contamination of a material or product with another
material or product.

5. Contamination Control
API as well as drug product manufacturing area, specifically clean room has
to be designed and maintained to prevent or minimize the contamination
from microorganisms , particulates etc
Objective is
To ensue the Patient safety (contamination = risk to the patients)
To ensure quality, purity, safety and efficacy of the product
To comply GMP and Regulatory Requirement
Minimize the product defective / failure
Quality of product should be built into design and systems during manufacturing,
NOT BY TESTING
Set the systems, practices and procedures to eliminate or minimisethe introduction
of contaminant into a product / process.
Microorganism: Bacteria, Yeast, Fungi, mold, pathogens etc
Particulates: Particles other than product, ie. Fiber, filth, fragments, hair, metal, plastics etc.

7. Good Manufacturing Practice
Q7 Good Manufacturing Practice emphasis the requirements
to prevent contamination and cross-contamination by
practicing Good personnel hygiene and sanitization.
It is mandatory and to ensure the compliance
To ensue Product quality and avoid rejection
To employee safety
To avoid recall and complaints
To avoid warning letter / import alert
To avoid loss of business
