What is low immunity?

Low immunity can be caused by:

having an illness like cancer or HIV/AIDS

having an autoimmune disease such as inflammatory bowel disease, type 1 diabetes, or multiple sclerosis

taking certain medications, including immunosuppressive drugs

being an older person with an ongoing (chronic) illness

being pregnant.

If you are unsure if you have low immunity or have questions, ask your doctor or other healthcare professional.

How to avoid food poisoning

Food may sometimes be contaminated by toxins or bugs like bacteria, parasites, or viruses. If food is handled incorrectly, you may get sick.

You can minimise your risk of catching a foodborne illness by:

knowing which foods are high risk, and avoiding them

selecting safer foods

following food safety guidelines when preparing and storing food.

Food poisoning – Food Standards Australia New Zealand

Foods that may pose a risk

Some types of foods may pose a greater risk than others. They need to be carefully prepared or avoided.

Dairy products

Most dairy products in New Zealand are pasteurised. Pasteurisation is a heat treatment that kills bugs in raw products. But these products can still become contaminated once opened.

Dairy foods that should be avoided when you have low immunity include:

raw/unpasteurised products

soft cheeses (unless cooked or eaten right after opening after being stored in the fridge)

commercially prepared and unpackaged smoothies or shakes

soft-serve ice cream.

If you have low immunity, you should not eat:

raw or undercooked meat, including poultry, fish or shellfish

raw or undercooked eggs

foods containing raw eggs (such as home-made mayonnaise, hollandaise sauce, Caesar dressing, some desserts)

cold meats, pâté, or cold-smoked fish.

Meat, poultry, seafood, and eggs should only be eaten if cooked until piping hot (over 70°C).
