2 / 4 Hour Rule (both ways)
(For the temperature control of potentially hazardous foods)
1.
- to be observed when preparing and serving food generally.
Reference: Appendix 1, page 183 & 184, Safe Food Australia; pages 26 & 62 of Standards; & pages 10
to12 Food Safety: Skills and knowledge for food businesses 2nd Edition, January 2001, FSANZ.
Any ready-to-eat, potentially hazardous food,
if it has been at temperatures between 5°C and 60°C:
For a total of less than 2 hours, must be refrigerated or used immediately;
For a total of more than 2 hours but less than 4 hours must be used immediately; or
For a total of 4 hours or longer, must be thrown out.
2.
- to be observed when preparing large quantities of food to be cooled down and
stored before further use.
Reference: Australia New Zealand Food Standards Code,
Standard 3.2.2. Division 3.7, Food Processing (3).
A food business must, when cooling cooked potentially hazardous food, cool the food:
(a) within 2 hours – from 60°C to 21°C; and
(b) within a further 4 hours – from 21°C to 5°C.

The 6 major groups of microbiological examples:
1. Bacteria - pathogenic types are Salmonella, Staphylococcus
aureus (‘Golden Staph’), Listeria monocytogenes and
Campylobacter.
Useful types, in moderation, are cultures in yogurt and ‘Yakult’.
2. Viruses - food-borne (food-carried) examples are Norwalk Virus
causing Gastroenteritis and Hepatitis A and E.
3. Moulds - blue cheese, that green piece of bread, yoghurts
and antibiotics (penicillin).
4. Yeasts - essential component of bread, beer (fermentation) and wine.
5. Parasites - protozoa, helminths
6. Algae

Food Spoilage
What are the different causes?
Explain how do you detect it?
CRICOS Provider Code: 01505M
RTO Number: 3045
DHS V3 2011
Food Spoilage
There can be a number of different causes:
- by yeast, mould or bacteria (generally not pathogenic) which can
change the texture, taste or colour of food.
- poor storage (bananas in the fridge), handling (physical damage)
and/or cross-contamination.
- chemical change in food, such as fats or oils going ranci or the absorption
of a strong chemical odour.
- enzyme changes in food, such as when fruit deteriorates naturally.
- pests affecting foods.
- a foreign object in food.
The quality of food is reduced and therefore unfit to eat,
but it is not diseased.
Food spoilage is easily detectable by its change in colour, texture,
odour, taste and appearance by using one of our senses.

Food Poisoning
How does it occur?
What are the main causes?
Outline the major difference between
food spoilage and food poisoning?
CRICOS Provider Code: 01505M
RTO Number: 3045
DHS V3 2011
Food Poisoning
This occurs when something in food or water makes a person sick
after consuming it.
The main causes are:
1. A toxic chemical in the food. Either a naturally occuring chemical,
such as solanine in green potatoes, rhubarb leaves or puffer fish, or
an accidental chemical contamination of food with a pesticide,
fertiliser or cleaning chemical.
2. An allergic reaction or intolerance (sensitivity) to a component of a food.
10% of the population suffers from one of these.
The most common being a nut allergy.
3. Growth of food poisoning micro-organisms in the food. They will not
necessarily alter the state of the food.
Food causing food poisoning will smell and taste normal.
CRICOS Provider Code: 01505M
RTO Number: 3045
DHS V3 2011
Infective and Toxic Food Poisoning
Infective Food Poisoning:
Occurs when live bacteria in the food get into the body and cause an infection.
It takes up to 48 hours to develop and there is often a headache and fever.
Toxic Food Poisoning:
Some bacteria cause a toxin when they grow (neurotoxins of Clostridium
Botulinum or botulism) and it is this toxic chemical that is poisonous to people.
Symptoms can occur within 30 minutes of eating the food.
Toxins may also be present in raw foods, such as shellfish, or ‘Red Tide’
associated with algal toxins accumulated in filter-feeding.
Note: high temperatures do not destroy a toxin if it is already in the food.
CRICOS Provider Code: 01505M
RTO Number: 3045

Food poisoning in Australia results in (on average):
- 120 deaths
- 18,000 hospital admissions
- 1.2 million visits to doctors
- 300,000 prescriptions for antibiotics
- 5.4 million cases of gastroenteritis (>15,000 a day!)
- 5,000 cases of Listeria
- 2.1 million days of lost work each year
The estimated annual cost of food poisoning
in Australia is $1.25 billion.
14% is from home!

6 factors for microbial growth:
What are the 6 factors?
Can you give an explanation
for each one?
CRICOS Provider Code: 01505M
RTO Number: 3045
DHS V3 2011
6 factors for microbial growth:
1. Temperature – Ideal conditions (warmth): 5C to 60C.
Optimum is 18C to 45C.
2. The amount of available water, referred to
as the water activity (aw)(moisture).
3. Food: available nutrients, particularly high-protein foods.
4. Time: normally 20 minutes to multiply, but it can take as little
as 15 minutes. Uses the process of Binary Fission - one cell
dividing into two.
5. A gaseous environment (Oxygen).
6. pH Level: Acidity is measured by pH, which not only
denotes if an environment is acidic, but also alkaline or neutral.
pH 7 is neutral, pH values less than 7 are described as acidic
and those above 7 as alkaline. The acidity of a product has a
selective effect on the microbial contaminants that will survive
and grow.
CRICOS Provider Code: 01505M
RTO Number: 3045
DHS V3 2011
Acidity - pH Scale explained
The pH scale ranges from 1 - 14:
1 is acidic and 14 alkali, sterile water is pH neutral at 7.

- High acid foods (pH 4.5 and below) are safe from pathogenic bacteria.
However, they may spoil through the growth of some bacteria,
e.g. yeast and mould.
- Low acid foods (pH 4.6 and above) are often the ones that spoil very
easily and they do allow the growth of pathogenic bacteria.
- 1 is battery acid; 2 is lemon juice; 3 is vinegar; 4 is soda; 8 is baking soda,
8 to 9 are stomach antacids; 11 to 12 is ammonia; and 12 is bleach.
CRICOS Provider Code: 01505M
RTO Number: 3045
DHS V3 2011
Bacterial Spores
- Bacillus cereus and Clostridium perfringens (the two most
common spore formers to cause food poisoning in Australia).
- the spore has a hard shell that protects it, making it
extremely robust against heat, dehydration and chemical:
they can survive extremes of physical conditions such as
chemical disinfection and heat treatment (+100C).
- there is some variation in resistance between bacterial
species, but generally they can survive even boiling
for up to 4 hours.
- spores survive in dormant conditions for very long periods
under adverse conditions, however when conditions are
favourable the spores germinate.

DHS V3 2011
Cleaning, Sanitising and Sterilisation
Cleaning
Achieved through using hot water (50C to 55C) and detergent.
Removes food scraps, grease and dirt. Moves bacteria around on the whole.
Rinsing with clean water should occur before sanitising.
A dishwasher needs to be at least 65C at this stage.
Sanitising
Achieved through either: +70C (+77C safer) hot, clean water for 30 seconds,
or chemical sanitiser left to air dry for at least 3 to 5 minutes
(according to manufacturer's instructions on the label or their MSDS).
Removes bacteria to a ‘safe level’.
A dishwasher needs to be at least 82C at this stage.
Sterilisation
Achieved through +100C steam, boiling water or disinfectants.
Kills all bacteria, except for some spores or toxins.

Sterilisation Spores will start to die at temperatures above 100C
(2.8 minutes at 121.1C is required to kill Clostridium Botulinum)
Spores will survive at and below 100C.
Safe zone – pathogenic bacteria start to die.
60C is the lower limit of the safe zone.
Danger zone – Bacteria grow well between 5C to 60C.
5C is the upper limit of the safe zone.
Safe zone
Pathogenic bacteria do not grow except Listeria.
Spoilage micro-organisms can also grow, all be it slowly.
Bacteria are dormant below -18C.
