Good Manufacturing Practices (GMP) is a system that ensures that the goods produced by various manufacturing facilities are consistently produced and controlled according to specified quality standards. There are GMP systems for everything from cosmetics to pharmaceutical products and of course, food. GMP looks at every aspect of the manufacturing process to guard against potential risks that can prove detrimental to its products. Cross-contamination, mislabeling, and adulteration are just a few of the things GMP aims to prevent. Thus it aims to make customers happy and satisfied by delivering them safe food.

Good Manufacturing Practices (GMP) is a system that ensures that the goods produced by various

standards. There are GMP systems for everything from cosmetics to pharmaceutical products

Good Manufacturing Practices:
It includes the following areas:
i. Personal Practices and Hygiene- This includes personnel arriving in the manufacturing unit
with clean hairs, hand, nails, body, no perfume or aftershave. They should wash and
sanitize their hands each time they enter the production area, after visiting the toilets,
after eating or drinking, after handling RM and cleaning. They should also remove their

neck chains, rings, earrings, wrist chains, watches and piercing, Leave personal items in
their locker, and change into company-provided clothing.
ii. Storage and Handling: Products that are produced should be stored and handled under
clean and sanitary conditions. For e.g.
•All items should be stored to avoid direct contact with the
floor or walking surfaces
•Product or ingredient containers must not be stored
immediately adjacent to containers with waste or non-
product item.
iii. Equipment Maintenance: Procedures describing preventive maintenance and calibration
of all the equipment and instruments that can affect food safety (eg: thermometers,
thermocouples, metal detectors, scales, pH meters)
iv. Equipment and Utensils: These should be clean-able and adequately installed and
maintained. Food contact surfaces should resist corrosion and be made of non-toxic

materials. Freezers and cold storage units must have a temperature monitoring device to
clearly show the compartment's inside temperature where food is stored.
v. Pest Control: Should be done to prevent transmission of diseases and pathogens. For this,
one should use traps and baits stations in strategic areas, or by using proofing doors,
windows etc. EFK (electronic fly killer) and insect light trap should be placed at a standard
height (at 6 feet) and the lights used in this should be replaced/checked one time per
months; pheromone traps are also used for cockroaches, these should be well placed &
operating,
vi. Housekeeping: Effective housekeeping can help control or eliminate workplace hazards.
Poor housekeeping practices frequently contribute to incidents. The 5S theory can best
explain this.

vii. Quality Control: It is a part of GMP which is concerned with sampling, specification, testing
and also organization, documentation.
Documenting GMP
To assist in the effective implementation of Good manufacturing practices (GMP) within the food
business, it is advisable to document how the food business will implement relevant Good
manufacturing practices (GMP). It is equally important to maintain records to support any Good
manufacturing practices (GMP).
The GMP Inspection
To ensure the effective implementation of Good manufacturing practices (GMP), it is beneficial
for the food business to undertake its own internal GMP inspection. This generally involves
reviewing the site visually to see if it complies with customer expectations and regulatory
requirements. This inspection should not merely be a "tick and flick" activity but a comprehensive
assessment of the site to determine the level of GMP compliance. A record of any GMP inspection
undertaken is required to be kept as evidence in a third-party certification audit. Any issues
identified during the GMP inspection should be quickly rectified, and a root cause analysis should
be performed to avoid reoccurrence.
Why are GMP food safety audits done?
A GMP Food Safety Audit focuses on preventing contamination and
reducing risk. GMP audits are done to verify the company's food safety
practices; it informs that the processes are effectively implemented,
including their HACCP Program. Thus, a GMP audit can help companies
improve their food safety and quality systems. It is a stepping stone to
prepare your company for accredited certification to SQF, FSSC 22000,
BRC. Different companies follow the different format of an audit
checklist. Following is an example of an audit checklist.

Conclusion:
One of the most critical components of GMP is quality control (QC)—the process of sampling,
testing and comparing results with pre-agreed specifications as part of the overall quality
assurance (QA) process. GMP helps to ensure the consistent quality and safety of products by
focusing on five key elements, which are often referred to as the 5 P's of GMP—people, premises,
processes, products and procedures (or paperwork/documentation). Moreover, if all five are
done well, there is a sixth P -profit!
Businesses in the food industry have a legal and moral responsibility to prepare food that is safe
for the consumer and by not implementing adequate good manufacturing practices (GMP), a
food business can risk its self reputation and will also risk its consumers.
