Food safety – tips for summer

 

 

Key points about food safety in summer

  • Sharing kai with friends and family is one of the great joys of the holiday season. But, as we all head outdoors for holiday parties, picnics and barbecues, it’s important to be careful about food safety.
  • You may be familiar with the four 'C' rules of food hygiene – clean, cook, cover and chill – but there might be other areas where your food hygiene skills need a bit of a refresher.
  • Harmful bacteria and parasites, like Campylobacter, E-coli and Salmonella can thrive in foods that aren’t cooked or handled properly. Eating contaminated foods can make anyone sick. 
  • Pregnant women are at increased risk of food poisoning, so take extra care if you’re pregnant or preparing food for someone who is.

1. Buy food that is safe

Check the ‘use by’ date to make sure food is fresh when you buy it. Avoid food with damaged packaging and buy fruit and vegetables that are slightly unripe or only just ripe – especially if you don't plan to eat them straight away.

2. Gathered food

Always wash food that you or others have gathered, eg, pūha or watercress. If you gather kai moana or seafood, check that the place you are collecting from is clean and free of pollution.

3. Keep hands and surfaces clean

Wash your hands before and after you handle raw foods. Make sure benchtops, cooking tools and barbecues are clean before you use them. When you prepare the meal, use separate utensils, plates and other tools to handle raw and cooked foods. After the meal, clean your benchtops and cooking tools well.

4. Rinse all fruits and veg

Rinse all of your fruit and vegetables under cold running water and then dry them with a clean cloth to help remove dirt and bacteria.

5. Preparing chicken 

Chicken is the main offender for spreading serious tummy bugs. It needs careful handling when it's raw. You might be great at remembering to wash your hands before and after touching raw chicken, but do you get carried away and wash the chicken before you prepare it? This common practice is a big no-no. Washing chicken in your kitchen sink can lead to contamination of your work surfaces, cloths and cooking utensils. Keep a special chopping board for preparing chicken and don't use that board for chopping up fruit and vegetables. Don't use the same knife to cut up chicken and other foods until it's been well washed. Read more about handling and cooking chicken(external link).

6. Keep cold foods cold

Set your fridge temperature between 2°C and 4°C. Most harmful bacteria cannot grow at low temperatures.

Keep cold dishes like salads and puddings in the fridge until you’re ready to eat them. Store raw meats and seafood in the fridge until right before you cook them. Cover them and place them on the fridge’s bottom shelf so their juices can’t drip onto other food. Keep meat products away from ready-to-eat food such as fruit and vegetables. Other meat and seafood (kai moana) are sources of bacterial contamination, not just chicken.

If you’re eating outdoors, use an icepack or chilly bin to keep food cold.

7. Fully cook meats and seafood

Cook chicken, mince and sausages right through, and cook pork and poultry until the juices run clear. Use a meat thermometer to check that your meat has been cooked to a safe temperature – at least 75°C in the thickest part of the meat.

You can take a vacuum-packed cooked ham straight from the fridge to the table. But if you like to glaze your ham and serve it hot, cook it at 160°C for 20 minutes per kilogram. You want the inside to reach at least 60°C – use a meat thermometer to check the temperature.

Eating cold ham of any kind when you are pregnant can come with the risk of a serious infection called listeria, which is harmful to the baby. Instead, cook or reheat ham until it’s piping hot (over 70°C) and eat it straight away. Learn more about how to eat safely when you are pregnant(external link)

8. Cover all dishes

Cover any dishes that are sitting out on the benchtop or table to protect your food from flies, ants and other bugs. Don’t leave them out of the fridge for more than 2 hours. Or store them in the fridge while your guests enjoy their first serving, then bring them back out when it’s time for the next course. If you think that food has been left out of the fridge for 4 or more hours, it is better to throw it out than risk getting sick. If in doubt, don't eat it!

9. Store leftovers carefully

Refrigerate or freeze leftover food within 2 hours after it was cooked, sealed in a clean, airtight container. You can keep a cooked cured ham in the fridge for up to 2 weeks. Cover it with a clean damp tea towel and change the towel every day.

Reheat leftovers until they are steaming hot (over 75°C), stirring well so they heat all the way through.

10. Most importantly

If you have been unwell or have any symptoms of sickness, leave the food preparation and serving to others. Don't risk passing on your germs to your whānau.
