Choose Pasteurised (Shop-Bought) Mayo

Commercial mayonnaise, salad cream and shop-bought dressings are made with pasteurised egg, so they're safe in pregnancy. Avoid homemade or restaurant mayo, aioli and dressings made with raw, unpasteurised egg.

Why Shop-Bought Mayo Is Safe

The pregnancy concern with mayonnaise is raw egg, which can carry salmonella. Commercial mayonnaise is made with pasteurised egg, the pasteurising process kills salmonella, so jars and squeezy bottles from the supermarket are safe to eat straight from the container.

When to Be Careful

Homemade mayonnaise, fresh aioli, some restaurant and deli dressings, hollandaise, and traditional Caesar dressing may be made with raw, unpasteurised egg. These are best avoided unless you know pasteurised egg was used. When eating out, ask whether dressings are made in-house with raw egg.

Storage Still Matters

Even safe mayo needs proper storage: keep it refrigerated after opening, don't leave mayo-based salads (like coleslaw or potato salad) out in the warmth for long, and observe use-by dates to avoid general food poisoning.
