Food safety for dinner parties: allergies, leftovers and keeping things cold

Nobody wants to be the host who made a guest ill. Fortunately, safe dinner parties come down to a handful of habits. They are not complicated, and once you have them, they fade into the background of your cooking.

Start with the guest list

Ask about allergies and diets

Put one line in your invitation: “Let me know about any allergies or dietary needs.” Ask again when guests arrive if you were not able to check. A true allergy is different from a preference, and some reactions can be serious.

• Common allergens include peanuts, tree nuts, milk, eggs, wheat, soy, fish, shellfish and sesame.
• Read labels on every packaged ingredient, even ones you buy often. Recipes change.
• Keep a list of what went into each dish, or save the packaging, in case someone asks.
• If a guest tells you their allergy is severe, ask what they need. Many will tell you precisely what is safe, or may bring their own dish.

Prevent cross-contact

• Wash boards, knives, bowls and spoons between uses.
• Use separate serving spoons for each dish.
• Cook the allergen-free dish first, on clean equipment, and cover it.
• Don’t dip a spoon back into a shared sauce after it has touched food.

If you cannot guarantee an allergen-free dish, say so. Honesty is kinder than a guess.

Keep hot food hot and cold food cold

Bacteria multiply fastest between about 4 and 60 degrees C. The goal is to keep food out of that range as much as possible.

• Cold food at 4 degrees C or below. Check your fridge with a thermometer.
• Hot food above 60 degrees C. Use a low oven, slow cooker or warming tray.
• Cooking temperatures. Poultry should reach 74 degrees C in the centre. Ground meat should reach about 71 degrees C. Whole cuts of pork and beef have their own recommended temperatures, which you can find on the Health Canada website. A probe thermometer takes the guesswork out.

The two-hour rule

Perishable food shouldn’t sit out for more than two hours, or one hour in hot weather. This includes buffets, cheese boards with soft cheeses, dips with dairy, egg dishes and anything with meat or fish.

• Serve cold dishes in small bowls set in a larger bowl of ice, or bring out refills from the fridge.
• Put out small batches of hot food and keep the rest warm.
• If food has been sitting out too long, discard it. Don’t “save” it by refrigerating.

Prep safely

• Wash your hands before cooking, after handling raw meat, and after touching your phone.
• Use separate boards for raw meat and for vegetables or bread.
• Don’t rinse raw chicken. It spreads bacteria around the sink.
• Thaw food in the fridge, not on the counter.
• Rinse fruit and vegetables, even if you plan to peel them.
• Keep raw meat on the lowest shelf, so it can’t drip on food below.

Leftovers

• Cool food quickly. Divide big pots into shallow containers and refrigerate within two hours.
• Label and date the containers.
• Eat leftovers within three to four days.
• Reheat until steaming hot throughout, around 74 degrees C, and only reheat once.
• Rice deserves special mention. Cooked rice left at room temperature can be a problem, so cool it fast and refrigerate promptly.

Send guests home with containers if they want them, but remind them to refrigerate the food soon after they arrive.

What can go wrong

• The “smells okay” test. Smell is not a reliable safety check. When in doubt, throw it out.
• Pregnancy, young children, older adults and weakened immune systems. These guests are more vulnerable to food-borne illness. Avoid serving raw or undercooked eggs, rare meat, unpasteurised dairy and raw sprouts when you know they are coming, and check official guidance.
• Overcrowded fridge. Air needs to circulate to keep food cold. Clear space before the party and use a cooler for drinks.
• A roast that is still pink inside. Check the temperature, not the colour.

A good habit for hosts

Take 10 minutes before guests arrive to check the fridge temperature, clear shelf space, set out clean cloths and put a thermometer by the stove. It is far easier than worrying later.
