What to look for on an egg label
When shopping for eggs you should find lots of information on the packaging, including the farming method, egg size, best-before date and nutrition information.
A number of egg farming methods are used in New Zealand, providing a range for consumer choice, and commercial egg farmers have agreed as a whole to voluntarily label their products.
Egg size and best-before date labelling is compulsory.
Egg size varies from about 40-80 grams per egg. These are sold by grade (4, 5, 6, 7, 8), based on a minimum size for the grade:
- Jumbo (8): 68g
- Large (7): 62g
- Standard (6): 53g
- Medium (5): 44g
- Pullet (4): 35g
- Mixed grade – a selection of different sized eggs
Choosing an egg size is usually based on preference and price, as larger eggs often cost slightly more, although some baking recipes may call for eggs of a particular size.
Eggs should also be labelled with a best-before date. Eggs refrigerated after purchase, at 4C or below, can be safely used up to the best-before date (around 35 days from being laid there will be little or no change in the egg quality) and after this date are recommended for use in baking.
