2 EGGS FOR CULINARY USES Chicken Duck Quail Ostrich Guinea fowl Goose Turkey Turtle Fish eggs (roe) Chicken eggs sold for culinary used are sold by grade and by weight. Often the egg shell itself is stamped with the correct classification and origin as well as on the egg carton itself. In most countries the label must also state the origin of the egg (local or import) and the raising method (free range, organic or stable raised)

3 EUROPEAN EGG LAWS AND STAMPING Shell Stamps By law, all EU produced eggs must be stamped on their shells with a code to indicate their provenance. Apart from other codes and logos, there must be a string of numbers and letters that look like this: 3UK123c The first number indicates the stocking conditions, based on the code shown below. 0 = organic 1 = free range 2 = barn eggs 3 = cage eggs This initial code is followed by the country (UK) and the farm s identity number (123c or 12345).

4 EUROPEAN EGG LAWS AND STAMPING Dating Codes Dates on egg boxes are to indicate the age or how old the eggs are. The maximum best before date is 28 days after laying. Eggs must be sold ( delivered to the consumer ) no more than 21 days after laying. Good practice operated by the better supermarkets cuts both these dates by a week so that the best before date is 21 days after laying, and the sell by or display until date is 14 days after laying.

5 EUROPEAN EGG LAWS AND STAMPING Class A, class B and industrial eggs When buying eggs as a consumer you should only get Class A eggs, which must be naturally clean, fresh eggs with intact shells and an air sac not exceeding 6mm in depth. The yolk must not move away from the centre of the egg on rotation. Such eggs are usually sorted by machine. Those that fail to make the grade are designated as Grade B eggs which are broken out and pasteurized for use by the food industry. In addition, there is another class of eggs called industrial eggs which are for non-food use only. These are largely used in cosmetic products such as shampoo and soap.

6 GRADING OF EGGS A Round, well centered yolk with small air cell (less than 5 mm deep). Clean, un-cracked shell with normal shape Size Jumbo Extra Large Large Medium Small Weight/Egg At least 70 grams At least 64 grams At least 56 grams At least 49 grams At least 42 grams Pee Wee (Extra small) Less than 42 grams

7 GRADING OF EGGS B Used for commercial baking or in institutional food factories. Very seldom sold at retail stores. Yolk is slightly flattened; white is thinner. Shell is un-cracked and may have a rough texture; and/or be slightly soiled and stained. C Lowest egg grade, used in production of processed egg products only. They are not sold in grocery stores.

15 STORAGE AND PURCHASE OF EGGS 1) Check each egg carefully. Discard any eggs with cracked shells 2) Keep Eggs under refrigeration until you are ready to cook them 3) Storage time for Eggs in their shell is 5-7 days at 33-38F/ 1-3C 4) Salmonella Enteritidis is a bacteria in some egg yolks which is killed at a temperature of 140 F (60C) for a minimum of 3.5 minutes, and at 160 F (70C) 5) Purchase Only Fresh Eggs and the right size that you need

16 HOW TO TEST IF EGGS ARE FRESH SALT WATER SOLUTION: Dilute 100grams of salt in 1 Liter of Cold Water Fresh Eggs will sink to the bottom and Older Eggs will swim to the top due to the larger air cell. LIGHT TEST: Hold s strong flash light behind the egg. The darker the egg yolk the older the egg. CRACKING TEST: Crack the egg open onto a flat plate. If the egg yolk is round and stands high is still fresh. The egg white will be compact and firm together. If the egg is not so fresh the egg white will be watery and runny and the egg yolk flat and depleted.
