Atlanta, Behind the usefulness as a healthy food, eggs are very susceptible to infection with Salmonella bacteria. But unfortunately, to find out if an egg is healthy or infected with bacteria hard to do. What can be done only to prevent it.
Eggs may contain harmful food bacteria called Salmonella enteritidis (S. enteritidis). These bacteria usually enter the egg through several ways, one of which is skin contamination of eggs with dirt.
Can also because it already has laying hens with Salmonella bacteria in the gut. In humans this bacteria found in intestines and feces (stool), especially for people already infected.
Can people distinguish healthy eggs with eggs that had been infected with Salmonella bacteria?
"No way can the community to find out if an egg has been contaminated or not. Because Salmonella can infect any type of chicken and there is no scientific evidence that could indicate a bacteria-free eggs," said Professor Rob Gravani, a professor of food science from Cornell University, as quoted by LiveScience, Thursday (19/08/2010).
Eggs are exposed to Salmonella cases must be proven through laboratory testing and can not diterawang with the naked eye.
Thus, according to Prof. Gravani if there is already infected with the announcement that the eggs should not eat people. Because the outside and within the infected egg would appear normal. Another way is to consider how to cook and keep the right so that the bacteria can die.
Outbreaks of Salmonella-infected eggs on a large scale has recently happened in Atlanta USA. The local government has attracted about 380 million eggs from the market due to exposure to Salmonella outbreaks.
Drug regulatory authorities and the United States Food Administration (FDA) is currently carrying out investigations to determine the cause of this outbreak of Salmonella in eggs. Investigations carried out in several places to eat that was serving food with raw eggs, the eggs are not cooked until soft and unpasteurized eggs.
Although unable to distinguish between healthy and infected eggs, there are some specific actions that can be done to reduce the risk of Salmonella infection.
The trick is quoted from CDC.gov are:
1. Do not eat eggs that are cracked or dirty (there is dirt on the skin of chicken eggs).
2. Washing hands, utensils with soap and water after contact with raw eggs.
3. Eggs should be cooked until the white and yellow ripe (the temperature reached 71 degrees Celsius) and then do not put off taking them.
4. Do not keep eggs warm or at room temperature for more than 2 hours.
5. Store eggs in the refrigerator if you do not want to use.
6. Avoid eating raw eggs.
7. Try not to eat food in the restaurant are made with raw eggs, undercooked or not in pasteurization.
8. Try to always keep eggs at a temperature of 45 degrees Fahrenheit (less than 7 degrees Celsius) over time.
If someone Salmonella poisoning, usually will have symptoms of fever, abdominal cramps and diarrhea about 12-72 hours after eating the food consumed. This illness usually lasts 4-7 days.
Someone who has a weak immune system, parents and infants are the group most vulnerable to illness due to Salmonella infection. In this group, the infection can spread from intestines to the bloodstream and other body parts .
