BBQ Food Safety: Cross-Contamination, Chilling and Leftovers

A successful barbecue is about more than flavour. Separating raw and cooked food, keeping chilled products cold and cooking carefully help reduce the risk of foodborne illness. This guide covers practical points for preparation, grilling and storing leftovers, based on consumer advice from the Netherlands Nutrition Centre (Voedingscentrum).

What is cross-contamination and how can you prevent it when grilling?

Cross-contamination occurs when pathogens from raw meat or fish reach cooked food or other products. They can be transferred by hands, utensils, dishes or leaking juices.

  • Use separate platters and chopping boards for raw products and ready-to-eat food.
  • Never put cooked meat back on the platter used for raw meat. Use a clean one.
  • Use clean utensils for cooked food. Do not use the same tongs that handled raw meat without cleaning them first.
  • Wash your hands after handling raw meat or fish and before touching salads, bread or other ready-to-eat food.
  • Prevent contact with raw meat juices. Keep raw products covered and separate from salads, sauces and other foods you will not heat again.

How do you keep meat, fish and salads chilled?

Set your fridge to 4 °C. Keep products that need chilling in the fridge until you need them. During the barbecue, bring out small amounts to cook or eat immediately and replenish them from the fridge.

Voedingscentrum advises discarding perishable food that has been outside the fridge for more than two hours. This is not a reason to leave food in the sun for two hours: keep time outside refrigeration as short as possible, especially in warm weather.

Keep raw and prepared products separate in the fridge too, and prevent raw meat juices from dripping onto other foods.

What level of doneness is safe for BBQ food?

The type of animal is not the only factor: the form of the meat and how it has been processed also matter. A general statement that beef is safe at a lower temperature is therefore too broad.

Whole cuts are different from minced and processed meat

Voedingscentrum states that whole cuts of beef or pork, such as steak or pork tenderloin, can be eaten pink, but that cooking them through remains the safest choice. Do not automatically apply this to every product made from beef or pork.

Raw or pink meat is not a suitable choice for pregnant people, young children, older adults or people with weakened immune systems. Cook meat thoroughly for these groups.

For processed meat, such as mince, burgers, sausages, skewers and marinated or cut-up meat, the advice is to check that it is fully cooked. Cook chicken thoroughly too, and follow any preparation instructions on the packaging.

A brown exterior is not a safety check

A dark crust or attractive grill marks do not tell you how hot the centre has become. Use a food thermometer rather than judging the cooking process solely by the outside.

Measure in the centre of the meat and keep the probe tip away from bone. Clean the probe before and after use and between checks of raw and cooked food. Read our guide to measuring internal temperature correctly. Temperature advice needs to be considered for the specific product and cooking method; do not turn one number into a universal safety rule for every meat and preparation.

The product guides provide further information about internal temperatures for chicken, internal temperatures for beef, internal temperatures for pork and internal temperatures for lamb. Keep the distinction between preferred doneness and food safety in mind.

How should you store and reheat BBQ leftovers?

Cool leftovers quickly and put them in the fridge within two hours. Do not wait until the end of a long barbecue evening. Store them in a tightly closed container at 4 °C and eat them within two days.

When reheating leftovers, heat them thoroughly until steaming hot throughout. Stir or turn them so that they heat evenly. Reheating is not a substitute for proper chilling and storage. Reheat only the portion you need, do so once, and discard anything left over after reheating.

StagePractical approach
Before and during the barbecueSet the fridge to 4 °C. Bring out small amounts and use them immediately.
Perishable food outside the fridgeKeep the time as short as possible. Discard food that has been outside the fridge for more than two hours.
Leftovers after cookingCool quickly and refrigerate in a covered container within two hours.
Leftovers in the fridgeStore tightly covered at 4 °C and eat within two days.
ReheatingReheat once until steaming hot throughout; ensure even heating and discard any leftovers afterwards.

The key points

  • Keep raw meat and fish separate from cooked and ready-to-eat food.
  • Use clean hands, platters and utensils.
  • Keep chilled products at 4 °C and bring out only small portions.
  • Distinguish whole cuts from minced or processed meat; always cook meat thoroughly for higher-risk groups.
  • Use a clean thermometer; a brown crust does not prove safe doneness.
  • Cool leftovers quickly, store them correctly and reheat them thoroughly once.
