All you need to know about food poisoning

It’s important for your household health to have a good understanding of food poisoning causes, and to take steps in food poisoning prevention. Read on for helpful approaches and advice!


what is salmonella

So, what is food poisoning? In the majority of food poisoning occurrences, the food that makes an individual unwell is contaminated with a virus, such as the norovirus, or by bacteria, such as E. coli, or salmonella. This leads to, for example, salmonella food poisoning. Food poisoning can put you out of commission for as long as a week, and who has time for that? Taking steps to ensure your food preparation is safe and hygienic is therefore vital.

Maintaining clean work surfaces and utensils before and after mealtimes is important for eliminating the spread of harmful viruses and food contamination. Using a specially formulated cleaning product such as Jif can help keep your home free of food poisoning bacteria.

What are food poisoning causes you should look out for?

Food contamination can occur at any stage during its manufacture, handling or cooking. For example, it can become contaminated by:

  • not cooking food completely – particularly meat

  • not properly storing food that needs to be refrigerated at a temperature below 5°C

  • allowing cooked food to be unrefrigerated for a long time

  • eating food that has come into contact with someone unwell or someone with diarrhoea and vomiting

  • cross-contamination – when food poisoning bacteria are spread between food, equipment and surfaces

How to prevent food poisoning

Those four Cs we mentioned earlier are a handy reminder of effective prevention of food poisoning:


Wash your hands often with warm water and soap, especially:

  • Following a bathroom visit, or changing a baby’s nappy

  • prior to preparing food

  • after touching raw food

  • after handling pets or bins


  • It’s vital to ensure food is cooked all the way through, particularly meat and seafood, to eliminate any food poisoning bacteria that could be present.

  • If you are warming up previously cooked food, ensure it is piping hot right through to the middle. Food should only be reheated one time.


  • Some food should be stored at the right temperature to avoid harmful food poisoning bacteria expanding and reproducing. Always read the instructions on packaging.

  • If food needs refrigeration, ensure your fridge is set to 0–5°C (32–41°F).

  • Cooked leftovers should be quickly cooled, ideally within an hour or two, and stored in the cool temperatures of your freezer or refrigerator.

Cross-contamination – and avoiding it

  • If you have touched raw food, always carefully wash your hands

  • Keep fresh and raw foods separate

  • When storing meat that’s raw, place it in sealable storage boxes right at the bottom of your refrigerator, preventing drips onto other foods.

  • Use separate chopping boards for ready-to-eat and raw food, or wash the boards thoroughly between preparing different food types.

  • Thoroughly clean knives, utensils or countertops if you have utilised them to prepare raw food.

  • Products such as Jif can help you tackle surfaces with ease.

  • Cooking will eliminate any harmful bacteria in meat or poultry, so you do not need to wash them first.

Now you’ve read through all the important advice to show you how to prevent food poisoning, why not put it into action and enjoy the benefits of a hygienic home free of food contamination!
