Transport of consumption eggs
At the layer farm, eggs are placed on either cardboard or plastic trays. Cardboard trays should preferably not be used again, and when so they should be checked thoroughly for polution and damage before returning to the the same farm, on the same containers. At the egg processing plant or packing station, the eggs are unloaded before checking and grading and the containers should be cleaned.
When eggs are transported to the supermarket they are packed in small size card board trays. In some parts of the world it is not permitted to wash the egg prior to consumption. In other countries like America this is done on a standard bases. The advantage of keeping the egg dry is that the cuticle stays intact from the egg, so the egg is better protected. The disadvantage is that possible contamination on the shell of the egg is not removed, creating the risk of contaminating the inside of the egg when breaking it. After washing, eggs should be preferably stored at low temperatures also during transport. This is not common in many EU countries.
Because eggs are sensitive, and can be infected with bacteria like Salmonellae, care should be taken when transporting the eggs.
Transport from the farm to the packing station and from the packing station to the retail is strictly separated. There are no big risks of recontamination during transport to the retail. The main hazard is changes in temperature which may lead to condens on the egg, and this may enable transport of micro-organisms through the shell into the egg.
