Eggs and Salmonella Enteritidis
Eggs have been associated with the foodborne illness causing bacteria Salmonella Enteritidis
(SE). There are many different types of Salmonella bacteria,
SE is just one of thousands of different types. In addition,
Salmonella and SE are found in a wide variety of food products
including meat, poultry, unpasteurized dairy products, fruits and
vegetables, and contaminated water.
It was once thought that Salmonella contaminated eggs through
contact with the shell. However, in the late 1980's it was
discovered that SE could be deposited inside the egg by the hen. Therefore,
refrigerating and cooking eggs is very important along with using
appropriate food handling techniques such as washing hands, counter
tops and all utensils that come in contact with food. By
refrigerating eggs, using proper handling, and cooking eggs
thoroughly, the chance of developing Salmonellosis from eggs can
be eliminated.
Some facts about eggs and SE:
- in the US, only one egg in 20,000 eggs is estimated to contain Salmonella Enteritidis
- SE when present is found in very low numbers (10-100
cells per egg)
- Salmonella does not grow well at cold temperatures, therefore,
refrigeration is very important.
- Properly cooking eggs destroys salmonella
- The incidence of salmonellosis from Salmonella Enteritidis
has declined 22% since 1996
