Councils:
Check the peel: In addition to the water test, check that the shell is clean and free of cracks. Eggs with damaged shells are at higher risk of being contaminated.

Smell as a last resort: If an egg floats but you’re not sure, crack the shell into a separate container. If it has an unpleasant smell, discard it immediately.
Store properly: Store eggs in the refrigerator to prolong their freshness. Place them on the main shelf, not on the door, as temperatures are more stable.
Use old eggs for certain recipes: Although older eggs aren’t ideal for stir-fries or omelets, they work well in recipes where they’re mixed with other ingredients, such as biscuits or cakes.
