The Ice Industry Code of Practice
This is a voluntary Code of Practice developed by the Packaged Ice Association of Australasia Inc. to be used where Ice is manufactured, stored or handled in any way whatsoever.
The Code of Practice will be enforced throughout the membership of PIAA through its rules and regulations of the Association.
It can be utilised by Regulatory Authorities as a standard in non PIAA member establishments.
The Code of Practice will assist members in fully understanding what is expected when dealing with practices and procedures involving ice. The information in this code forms part of supportive information to the genetic PIAA Food Safety plan for Ice.
Should this code be breached, the PIAA have detailed the mechanism for ensuing compliance with….
- Open and transparent procedures.
- Mechanism for dealing with complaints and contravention of the code.
- A review mechanism.
- Options for referring the matter to the relevant enforcement agency for appropriate action.
- Appeal mechanism.
PIAA will ensure the Code of Practice is widely distributed throughout the food industry where ice is processed or used. PIAA will also endeavour to arrange avenues of training for its members to assist in the practical implementations of this Code of Practice.
The Code of Practice is divided into the following areas:
- Operational/Manufacturing Practices.
- Personal Hygiene/Food Safety Practices.
- Cleaning & Sanitizing.
- Pest Control.

Structural / Maintenance
This relates to the main building/s used in the manufacture/storage of ice, its equipment and the building surrounds. This code is read in conjunction but not in contravention of the food safety code within the relevant state.
Ice Machines, Loose Ice Storage, Automatic Handling, Packaging and Packaged Ice, Storage Areas.
· Sound, smooth, impervious and durable surface condition and maintained in good repair.
(Ice machines should be of solid construction with protective coatings and preferably be insulated. All walls and ceilings to the internal compartment of the ice machine should be made of a material which will enable it to be easily kept clean.)
· Fully enclosed and insulated machine area.
(Small ice machines should be located in an enclosed area that conforms with the requirements for the manufacturing and preparation of food.
Large ice machine units not totally enclosed, should be located in a room that complies with the requirements for the production of food.
Totally enclosed large ice machine units should have the associated ice crusher, chutes and augers fully enclosed).
- Protective coatings or non-corrosive material surfaces to be used.
- Easy access to enable servicing of the machines and easy cleaning.
- Located in an area with easily cleanable surfaces and drained to prevent pondage of water/condensate.
(Generally the ice making equipment should be positioned internally within the manufacturing premises. It should be positioned to allow for good air circulation and permit easy access to cleaning).
· Temperature control to maintain ice in the frozen form free from melted water.
(Location is important to the efficient functioning of ice machines. Ice machines produce considerable heat and thus require good air circulation or water cooling for smooth, efficient operation, keeping power costs to a minimum. The Regulatory Authority should be consulted when selecting the location of ice-making equipment).
Ice Makers/Ice Crushers/Chutes and Augers.
· Should be fully enclosed against airborne contamination and vermin.

No bait or non-food grade products shall be stored with ice, in the ice production area or transported with ice to prevent cross contamination. Contents of all containers are to be easily identified and properly labelled to prevent accidental use or contact. Working areas must be kept free from rubbish and litter. Waste containers are to be maintained clean, covered and properly used. Vermin control must be effective and there should be no rodent harbourage. Only authorised pesticides should be used. Pesticide containers must be clearly labelled and stored in a secure storeroom. No birds or animals are to be kept on the premises).
· All food contact surfaces (including scoops, shovels and rakes) continually maintained in a clean and sanitized condition.
(Ancillary equipment should be cleaned regularly with a cleansing agent, sanitized and allowed to air dry. Steps to prevent recontamination should be taken such as storing an ice scoop in a covered plastic container after use).
· Bags used for the packaging shall be :
1. Stored in a dry vermin and dust proof enclosure and protected against contamination.
2. of sound strength and quality to prevent fracture or tearing during handling.
3. sealed with a tamperproof method (twist ties and plastic clips not acceptable).
4. restricted from reuse or repackaging.
5. labelled in an easily identified conspicuous manner with size weight and manufacturers contact details on the package in accordance with state and federal labelling legislation.
6. bags must bear sequential numbering and use by date.

(Working areas must be kept free from rubbish and litter to reduce contamination).
Personal Hygiene / Food Safety.
· Handwashing whenever hands become contaminated in any way whatsoever while processing ice. Drying of hands using
· Disposable paper towels reduce cross contamination.
(Wash your hands thoroughly with soap and warm/hot water immediately before commencing or resuming work, between tasks and after visiting the toilet, smoking, handling a rubbish container, handkerchief or nasal tissue, performing cleaning duties or after handling fish tubs and bait. Do not wipe your hands on clothing or on anything other than a clean disposable towel).

· Do not spit or smoke.
· Do not work with package ice if you are ill (cold symptoms, vomiting or diarrhoea, skin infections on the hands) or affected with a disease or are a carrier of a disease that may be transmitted by contamination of food. Notify your supervisor immediately who may direct you to work in a non food area or send you home or to seek medical treatment.
· Do not work in an area where contamination of food may occur if you have a boil, infected wound or sore, or a bandage or dressing that is not waterproof on any part of your body.
· Do not put your hands or fingers in your mouth, nose, hair, eyes, ears or other parts of your body.
· Do not breathe into any package that is to be used for ice.
Cleaning and Sanitizing.
· A cleaning and sanitizing schedule will be developed and implemented.
(Stainless steel will corrode when exposed to certain chemicals such as chlorine compounds. Since chlorine gases and compounds are expelled from water during ice production, stainless steel surfaces should be cleaned periodically with a non-chlorine mild abrasive cleaner. Packaging equipment should be cleaned regularly with a cleaning agent, sanitized and allowed to dry).
· Only food grade or approved cleaning and sanitizing chemicals will be used.
· Store and use only approved chemicals to prevent cross-contamination.
