What foods do bacteria prefer to grow in
Bacteria prefer to grow in food which is high in protein,vitamins and minerals e.g chicken,fish,milk
Does bacteria need moister or dryness to thrive
Bacteria needs moisture to grow and therefore cannot multiply in dry foods. However, once dry food is reconstructed then the food becomes an ideal breeding ground for bacteria
Examples of reconstructed foods
Custard powder
Packet of soup
Pot noodle
Does bacteria like hot or cold places
Bacteria like to be kept warm-they multiply most rapidly in warm conditions
What happens too the bacteria at different temperatures
64-100°c ——bacteria are destroyed
5-63°c —— danger zone perfect for bacteria growth and multiplication
1-4°c ——- bacteria multiply slowly in the fridge
-18. —— bacteria are dormant in the freezer
How long do bacteria need to grow
If bacteria are fine perfect conditions I.e food,moisture,and warmth and they have enough time they will multiply rapidly
In the best conditions they multiply x2 every 20 mins
How can shoppers be safe while putting food in bags
Consumers may need to be reminded about the importance of packing food safely in the super market to reduce the risk of bacteria being transferred from raw meat to other foods
How can people be safe when storing food
Once food is brought home it is essential that it is stored in the right place in the kitchen
What are use by dates mean in packaging
High risk foods (bacteria grow easily in them) will have a use by date. They food must be eaten by this date otherwise it is spoiled and inedible
Best before dates
Foods that are dry and low risk stay safe to eat for longs periods of time. This means the food will be at the best quality up until this date. They are usually dried foods,canned,in jars or packets
Examples of potential causes of food poisoning
Not cooking thoroughly
Not stored properly
Not handeling food hygienically
