What is a PRP?

A PRP is also known as a prerequisite program. This umbrella term describes all general activities that affect food safety. These would be activities that are not part of a specific HACCP plan. It is designed to create a favourable environment to ensure food safety.

When a PRP is well designed and followed properly it allows for the HACCP team to concentrate on hazards that apply directly to the product and not have to spend time focussing on hazards that arise from the surrounding environment. The PRP can directly affect how successful a HACCP program is and should be taken very seriously.

A PRP would need to include the premises where the food is made, where the food is purchased and how it is stored and transported to and from the factory. The equipment used in the facility and the personal hygiene of staff members would also be part of the PRP. PRPs also include sanitation, pest control and product recall and its traceability.

What is GMP? Part 2

It is necessary for GMP (Good Manufacturing Practises) to be followed in conjunction with HACCP in the food industry. For GMP to be complied with all cleaning chemicals should be stored in a separate lockable storage area which is away for the production and food storage area.

The effectiveness of disinfectants shall be verified at planned intervals.

Dilution rates need to be understood as overuse can lead to residues which can compromise food safety and be costly due to wastage of product. Underuse or under dilution can lead to your cleaning not being adequate.

Staff also need to be familiar with first aid requirements for all cleaning chemicals in case of accidental use or spillage.

What is GMP? Part 1

GMP is a method of manufacturing a product that will ensure a good quality product. GMP guidelines are not instructions on how to manufacture products but rather a series of general principles that must be observed during manufacturing.

Above all, staff training is vital. All staff will need to receive proper training and be monitored.

GMP would include training staff to be aware of the correct cleaning chemicals to use in specific areas. Staff would also need to be trained in how exactly to use the cleaning chemicals and what  equipment will be needed.  This would include the use safety gear when required. There should be a list of all the cleaning chemicals used.

Cleaning with HACCP

When adopting the HACCP method of cleaning your kitchen or food factory there are very specific ways to clean. There are different types of cleaning involved. Maintenance cleaning will be vastly different from deep cleaning. The frequency of cleaning here is the absolute minimum cleaning that should occur.

Contact surfaces must be cleaned continuously . Floors in kitchens and food factories should be cleaned after each shift. Daily cleaning is required for ovens, stove tops, grills, bain-maries and plate warmers. Waste bins will also need thorough daily cleaning. Walls and ceilings in kitchens should be cleaned once a week. Cleaning out grease traps and floor drains should also be done once a week.

Wherever possible it is best to have liquid cleaning chemicals provided to staff in spray bottles. Areas should then be cleaned using colour-coded cloths or brushes.

How to clean with HACCP

The HACCP cleaning system is typically instituted in food factories and kitchens.

In order for the HACCP system to be effective the correct cleaning equipment should be used. This cleaning equipment should be colour coded so that a particular item is used in a particular area. This helps to prevent cross-contamination of bacteria. Therefore each particular area will have it’s own set of cleaning equipment.

This will also apply to the cleaning chemicals used. The cleaning chemicals used to clean a food factory or kitchen need to be effective in killing bacteria to ensure food safety.  Only approved cleaning chemicals may be used! Using approved cleaning chemicals can minimise the risk of contamination of food on contact surfaces.

There will also need to be a master cleaning schedule in place which will involve deep, maintenence and daily cleaning procedures. Cleaning records will need to be kept.

It is also necessary to test for any residues after the food factory has been cleaned to ensure that cleaning was effective.

What is HACCP

The acronym HACCP stands for hazard analysis critical control point. It was a system developed by NASA to ensure food safety for astronauts. Since then the HACCP system has become internationally recognised as the best system for food safety assurance. HACCP can be described as a food safety management system that affects all stages of food production and distribution. It is about the prevention of hazards rather than the inspection of the finished product.

The World Health Organisation (WHO) has adopted the HACCP system as the most effective way of controlling foodborne diseases. 

The HACCP system is now being used in the cosmetic and pharmaceutical industries.

Adopting the HACCP system will involve following very specific cleaning and handling procedures through every stage of manufacture.
