Bacteria cannot be avoided, or ignored, in the food industry, but, in most cases, the risks can be eliminated by good galley practice and safe food handling procedures. Which two of the following are the main strategies designed to reduce the negative impact of bacteria in food?
Prevent the food becoming contaminated.
Prevent the bacteria from multiplying.
Adding ingredients which will kill the bacteria once inside the human body.
There are not really any effective strategies to reduce the negative impact of bacteria in food.
Answer
Besides contaminated food, what else may be a common and direct source of viral food poisoning on board ship, as described in this module?
The water supply.
The ovens.
The refrigerators and freezer stores.
The cutlery and glassware.
Answer
By what name are the poisons associated with food poisoning known?
Toxins.
Gastrointestinal agents.
Venoms.
Amines.
Food stored in a refrigerator should be covered, wrapped or placed in containers to prevent drying out and cross-contamination. As explained in this training module, what else will such procedures help to prevent?
The absorption of odours.
Rapid discoloration of the food.
Sweating and build-up of moisture on the food surface.
The food having to be thrown away after it reaches its “use by” date.
How can wastage best be prevented with prepared cold dishes?
Only make a limited amount and accept there may not be enough to serve everybody.
Part of the dish can be kept back in the refrigerator or cold-room until needed to replace food that has been consumed.
Immediately freeze half of the dish when prepared and defrost it again in the microwave immediately before service.
Keep the dish covered during service, to keep it cool.
How may cold food best be kept at the required temperature on a buffet?
By nesting the dish in a bowl of ice.
By turning up the air conditioning.
By placing it in the freezer for half an hour before serving.
By keeping it away from hot food.
How might you best determine if a joint of meat is cooked right through?
By cutting the joint in half and tasting a piece from the middle.

By ensuring that the oven is set at a minimum of 180 °C (356 °F).
By using a meat thermometer.
How would you treat a cooked joint of meat and some uncooked sausages, both required for the same evening meal?
I would keep them apart. It is critical to always keep raw and cooked food completely separate.
I would store them together until required.
I would not be able to use them in the same meal.
I would add the sausages to the container containing the joint of meat and reheat for 15 minutes. In this way, they are served at the same temperature.

No, raw meat and cooked meat should never be mixed together.
Yes, this is a good way to prevent wastage.
Yes, provided more than half is the cooked portion.
Yes, but only if the mixture is to be heated immediately.
Is it safe to eat food that has reached its “use by” date?
No.
Yes, provided it smells alright.
Yes, provided it looks alright.
Yes, so long as it is thoroughly cooked before serving.
Prior to cooking, which one of the following is the usual technique employed, to ensure raw beans are safe to eat?
They should be thoroughly soaked.
They should be dry roasted for at least 3 minutes.
They should be salted and left for at least one hour.

Overheated milk.
Bacterial infections originating in the noses and throats of food handlers or cuts on their skin.
Cooked meat, which has been allowed to cool and is later re-used in another meal.
Contaminated water.
To prevent the growth of bacteria in food, we must ensure that food is maintained outside a temperature range known as the “danger zone”. What are the generally accepted limits of that zone, as quoted in this training module?
5 °C to 63 °C (41 °F to 145 °F).
0 °C to 100 °C (32 °F to 212 °F).

What is “Ciguatera”?
The name given to food poisoning which results from eating contaminated fish.
The flowery green leaves on the tops of carrots.

It should be frozen for future use.
It should be washed and used in a salad dish the following day.
What should you do if you discover an egg with a cracked shell in the tray you are using to prepare omelettes?
Break it into a separate dish and see what it smells like.
Throw it away.
Use it, as it will not matter in a mix of several eggs.
Put it to one side to hard-boil for use in a salad dish.

It must be spooned over the fruit immediately and the dishes set to one side ready for serving when required.
It should be monitored until needed and, if it appears to be thickening, a few spoons of milk should be added and stirred in.
What type of fish is particularly associated with Ciguatera food poisoning?
Large reef fish.
Small shoal fish.
Shellfish.

When chilling food, why is it important to achieve rapid but controlled cooling of the surface?
Because this is where the bulk of bacterial contamination occurs.
Because discoloration will occur if cooling is too slow.
Because freeze contamination will occur if the process takes too long.
Because that is the part in contact with the packaging.
When defrosting food in cold water, what should be done with the water?
It should be changed every 30 minutes, to ensure the thawing process continues evenly.
If the food remains partly frozen, add a little hot water and defrost for an additional 15 minutes.
The water must not be disturbed during the defrosting process.
It should be changed every 2 hours.
When defrosting frozen meat in cold water, it must be in a leak-proof package or plastic bag. If the bag leaks, bacteria from the air or surrounding environment could be introduced into the food. What is the other risk described in this training module?
The meat will discolour.
The meat will give off an offensive smell.
The packaging will start to disintegrate and small bits of plastic may stick to the meat during cooking.
The meat tissue may absorb water, resulting in a watery product.
When food has been cooked in a microwave oven, why is it important to allow the required “standing time”?
Because it completes the cooking process.
So that any oil or fat drains away.
So that any food which has risen during cooking returns to its proper size and shape.
So that the stewards do not burn their fingers during service.
When marinating foods, where should they be placed?
In a refrigerator or coldroom.
On a work bench.

That it will be served within 24 hours.
That it will be served immediately.

Use them in the salad anyway and hope that nobody notices.

Which viral food poisoning is alternatively known as the “Cruise Ship Illness”?

Why can the Ciguatera toxins not be neutralised simply by cooking the fish to a specified temperature?
Because they will return as the fish cools to eating temperature.
Because the toxins inhabit the skin of the fish and they are transferred to the cooking liquor as it is cooked.
Because these toxins are particularly heat resistant.
Because the toxins are contained in the bones of the fish and are released into the flesh by cooking.
Why must food stock be “rotated”?
To ensure older items are consumed first.
To ensure even weight distribution on storage shelves over time.
So that the cook knows what foods he has in the store and can vary the menus.
Because it is a security requirement under the ISPS Code.
