Chief Executive Officer
WHAT IS GOOD
MANUFACTURING
PRACTICES?
procedures to ensure products are
manufactured to meet a certain quality and
safety requirement
 these procedures describe the methods,
equipment, facilities and controls for all
manufactured goods
GOOD MANUFACTURING
PRACTICES
prerequisite program for food quality and
safety plans e.g. HACCP, ISO9000
GMPs -develop,implement, review and
verify:in place and effective
GMP programs ensure HACCP plans focus
on CCPs to produce safe food

CLEANING PROGRAMME
• a planned schedule of how, when and where
cleaning will be done
• include written instructions giving details of:
the frequency,
the method,
the strength,
type of detergent and sanitiser to be used,
any variations,
how to dismantle the equipment for cleaning,
method of application
CLEANING METHODS
The are 5 cleaning methods:
•
•
•
•
•
manual
soak
pressure
foam
in-place cleaning
DETERGENTS &
SANITISING
 Types of detergents
• acidic detergents
• alkali detergents
 Methods of sanitising
• steam sanitising
• hot-water
• chemical sanitising eg halogens, Na
hypochlorite, chlorine releasing comp. ,
quaternary amm. comp., phenolics and
other surfactants (acid anionics etc)
CLEANING PROCEDURE
• dry clean the entire area
• wet all equipment by hosing with lowpressure water at a temperature less than
45 °C
• apply a suitable detergent
• rinse off detergent
• apply sanitiser to all surface
• rinse off surfaces with hot water at 82 °C
• drain off all water on equipment and floors
CLEANING REMOVABLE
EQUIPMENT

• immerse individually in hot water (55-60°C)
containing a detergent or detergent/sanitiser
• after soaking 20 mins scrub all surfaces and rinse
clean with warm water
• if only detergent is used than repeat step above
and rinse off with water (82°C)
• place all equipment in such a manner that
surfaces are not touching and allows to air-dry
HOW CLEAN IS CLEAN
Two types of determination

• microbiological test
replica or contact method eg agar
slice method, rodac plates and cellulose tape
swab method eg agar plate swab and
rinse method
