hygiene Flashcards
(43 cards)
importance of hygienic work practices
- Reduce food borne illnesses/ food poisoning
- Prevent cross contamination
- Minimise pests/ rodents
- Prevent name and shame list - ensure business reputation is upheld
- It is a law (legislation)
- Customer expect it
Consequences of poor hygienic work practises:
Customer • Food poisoning • Illness • Allergic reactions Worker • Loss of jobs • Higher staff absenteeism • Increased staff turnover • Staff may be fired • Staff warnings may be issued if procedures are not followed Workplace • Business shut down • Loss of reputation • Name and shame list • Fines • Increased wastage • Increased costs • Pest infestation
What is personal hygiene
- An individual’s own hygiene
- Showering daily
- Wearing deodorant
- Wearing a clean uniform
- No jewellery
- Hair tied back
- No artificial nails or polish
- Washing hand thoroughly and use of gloves
Food Preparation and storage
- Workspaces and equipment clean and sanitised before, during and after working with food
- Storing food away from the danger zone (5-60)
- Containers with lids and labels
- Shelving; layers of fridge- raw on bottom, cooked on top
- Heavy food/supplies/containers on bottom shelf
- Stock rotation: FIFO - first in first out
- Storerooms and coolrooms must be clean
‘Ready to eat’ food items
- Presented on clean serving ware free of chips or cracks
- Chips/cracks = harmful bacteria hard to remove (causes food poisoning)
- Food prepared earlier needs to be in an environment that will not cause it to become hazardous
- Eg. Bain-marie keeps food above 60 C
- Time should be monitored
Service of food and beverages
- No touching tines of forks
- No touching blades of knives
- Wine glasses held by stem
- Takeaway in clean containers/wrappings
- May have to wear cotton gloves to minimise contact
Linen
- Napkins, dishcloths, tablecloths, bar mats and cleaning cloths
- Cleaning linen and table linen NOT MIXED
- Dirty linen and clean linen NOT MIXED
- Dirty linen handled with gloves and placed in a cloth bag
- Store fresh linen in a clear dry cupboard
Cleaning and sanitising
- Cleaning = remove dirt, food scraps and dust
- Sanitising = reduce bacteria to a safe level
- Sanitise = spray, hot water 60 degrees sanitises equipment
- Cleaning always takes place before sanitising
Waste Disposal
- Handler needs to wear gloves and wash hands thoroughly before/after the task
- Garbage removed regularly before it becomes a health hazard
- Recycle/compost = environmentally friendly
- Wash bins and liners in bins
- Glass- wrap in paper bag to dispose
- Reduces pests, vermin
Pest Control
- Hygiene hazard
- No unsealed food items or scraps in bin at end of shift
- Fix broken tiles, window screens, visible wall cracks
- Wash floors
- Pest control sprays/ services
Hand washing + 6 step technique
- ONE OF THE MOST EFFECTIVE AND VALUABLE MEANS OF PREVENTING CONTAMINATION
- Hands washed when preparing, cooking, handling and serving food
- Washed after going to the toilet, handling raw eggs meat or poultry, smoking, sneezing, coughing and touching the face or hair
- Designated hand washing sink with warm running water, soap and air dryer/single use paper towels
- Process:
1. Wash with warm running water
2. Lather with soap
3. Scrub for min 20 seconds
4. Rinse under running water
5. Dry with clean paper towel or air dryer
6. Turn off water using paper towel
Factors affecting food safety: Handling foods and beverages
- Gloves worn when handling food to prevent contamination
- Gloves changed every time they become contaminated
- Correct food handling procedures should be followed
Factors affecting food safety: Surfaces
- Food prep: Chopping boards, utensils, cookware, serving ware, storage containers, plastic wrap, bags, foils and napkins
- Surfaces may be present with a food safety risk if they come into contact with dust, food scraps or unclean surfaces
- Chopping boards are colour coded to help prevent contamination
- white; dairy and bakery goods
- green; fruit and vegetables
- yellow; poultry
- red; raw meat
- brown; cooked meat
- blue; seafood
Factors affecting food safety: Personal hygiene
- Poor personal hygiene presents a risk to the food being prepared
- Bacteria can be transferred
- Good hygiene; clean uniform, hand washing, clean shaven, no jewellery
- Not wearing uniform to and from work to prevent contamination
Factors affecting food safety: Personal health issues
- Anyone working with food who is suffering an infectious disease is legally required to report it to their employer
- Illnesses can be transferred through touch, air and saliva
- Cuts and abrasions must be reported
- Cuts must have a blue band aid or other bright colour; gloves must be worn to eliminate wounds coming into contact with food
Factors affecting food safety: Environmental hygiene
- An environmental hazard results from failure to maintain clean premises (floors, sinks) and equipment (utensils, appliances)
- If kept unsanitary; pests, insects and vermin occur
- Regular removal of garbage
Factors affecting food safety: Work Practices
- Establishments will have procedures about food handling
- If procedures are not followed; food safety may be at risk
- Examples; wearing gloves, coloured chopping boards, holding cutlery by handles, removing aprons when going bathroom
Eliminating and minimising hazards:
- Establishment needs to anticipate where hazards could occur and either eliminating or minimising these
- Training staff minimises food safety hazards, they know why they are performing a task and consequences that occur if they don’t do it
- Eg Cross contamination = implement appropriate control measures such as uniform and personal hygiene standards, environmental hygiene standards and practices, food prep and handling procedures
Hazard Analysis and Critical Control points (HACCP)
A method of ensuring food safety with the aim of preventing food hazards
- Gives staff confidence that food is safe to eat
- Analyse from the arrival, to storage, to preparation, to cooking and service
- At each step of the production of the dish, control measures are put into place to prevent hazards from contamination
7 principals of HACCP + description
- Conduct a hazard analysis
Develop a list of hazards
- Conduct a hazard analysis
- Identify critical control points
Control can be applied and is essential to prevent or eliminate a food safety hazard or reduce it to an acceptable level.
- Identify critical control points
- Establish critical limits
A critical limit is a maximum and/or minimum value to which a biological, chemical or physical parameter must be controlled at a CCP
- Establish critical limits
- Establish monitoring procedures
Monitoring is a planned sequence of observations or measurements to assess whether a CCP is under control and to produce an accurate record for future use in verification.
- Establish monitoring procedures
- Establish corrective action
prevent foods which may be hazardous from reaching consumers.
- Establish corrective action
- Establish verification procedures
Evaluating whether the facility’s HACCP system is functioning according to the HACCP plan. Initial validation of the HACCP plan to determine that the plan is scientifically and technically sound, that all hazards have been identified and that if the HACCP plan is properly implemented these hazards will be effectively controlled.
- Establish verification procedures
- Establish record keeping and documentation process
Work practises associated with HACCP:
- Temperature checking raw ingredients as they are received
- Conducting visual inspections of fruit and veg to ensure no pest infestation
- Performing stock rotation (FIFO) to prevent stock from going out
- Using timers and recording display times for food waiting to be purchased
- Thermometer to check the internal temperature of cooked meats
- Filling in cleaning rosters and sign off sheets
Signs of damaged, deteriorated, spoiled or out-of-date food
- Bruising, wilting, or damage to the skin or leaves of vegetables
- Over-ripening of fruits such as berries and stone fruits
- Blue, blue, green or white mould
- Slimy feel on products such as bacon or ham
- Unpleasant or unnatural smell such as “off” meat
- Damaged or opened packaging, broken seals on bottles
- “Blown” or dented cans and bottles
- Unfamiliar textures; lumpy yogurt
Define: Contaminant, Contamination, Cross-contamination, Potentially hazardous food
- Contaminant: substances that make something less pure or make it poisonous
- Contamination: action of making something impure or harmful
- Cross-contamination: occurs when harmful bacteria or allergens are spread to food. They might be transferred from other food, surfaces, hands or equipment
- Potentially hazardous food: may have naturally occurring bacteria already within them. Some foods are considered high risk because they are high in protein and high in acid.
Causes of contamination:
Physical: - hair, chips of nail polish, rubbish from packaging, dust and insects
Chemical: caused by failing to thoroughly wash fruit and vegetables before preparation, or not following cleaning procedures - e.g. using sanitiser spray near uncovered ready-to-eat food
Microbiological: -may be present in the food already, r may have been introduced through poor hygiene and food handling procedures + bacteria that causes illness; toxin or poison produced by bacteria
