Salmonella infection

Diseases are salmonella infection satisfactory and not poisoning food and produce from eating food containing large numbers of microbes live bacteria Salmonella enteritidis, which produces toxins internal Endotoxin and processing food cooking and boiling and icing or freezing does not have the ability to neutralize toxin that is produced by these bacteria and there 1700 almost strain of Salmonella and are able to make a satisfactory infection.

Microbial characteristics of salmonella:

Salmonella bacteria rod shape is Mottagrthma negative Gram, and considered one of the bacterial strains that do not have the ability to resist heat, until it happens poisoning with the bacteria must be in food, these bacteria which can grow on low temperature also any that could contaminate a large number foods stored in refrigerators.

Modes of transmission and infection:

In general, most types of salmonella live in the intestines of wild and domestic animals and birds these bacteria infect the ovaries or fallopian tubes in the chicken and then contaminated eggs before they made up the outer shell and do not show any symptoms on infected birds.

And bacteria can be transmitted on the outer shell of the egg, due to the presence of the egg inside the hen's body in the same channel out feces, can also be contaminated eggs with bacteria while in the nest from poultry feces through the pores of the outer shell ..

It may also be animals or poultry carriers of the bacteria before slaughter, but if they are not as well as they may be contaminated after slaughter if slaughterhouses or tools that are the transfer of such meat is clean and contaminated with salmonella bacteria.

And can be transmitted infection bacteria salmonella from infected person or carrier have if those who are preparing and preparing food can bacteria that spreads easily from eggs to any type of food, through contact with eggs for dishes or tools or surfaces processing and then transmitted to the food touching it. If you have been in contact with the egg or outer shell food or fell a few points from egg whites or yolk food the bacteria will spread in this food.

And contaminated foods of animal origin such as poultry, eggs, meat and fish, water sources and soil bacteria salmonella. There are also some animals that carry the bacteria on their skin and hair like cats, so if a player young children cats that may be carriers of the microbe, the opportunity to move them contained microbe.

: Salmonellosis symptoms of salmonella poisoning

Show symptoms of poisoning with Salmonella after eating contaminated food at about 6 hours to 12 hours and symptoms begin often in the form of cramps in the intestine accompanied by severe diarrhea caused by irritation of the walls of Interior of the intestines may be accompanied by the departure of mucus or blood with stool occurs high temperature between 50 to 70 cent of cases.

These symptoms also associated with vomiting in a small number of cases of the disease.
The symptoms are similar to symptoms of other diseases such as hepatitis, amoebas and malaria. The show some medical tests injured patient with anemia and a shortage of white blood cells or a decrease in platelets is also possible that the bacteria cause a rise in liver enzymes, may increase these possibilities after taking intensive treatment of antibiotics, which makes the patient feel wasted, lethargy and general weakness of some thing. The severity of these symptoms vary from one person to another, and to another poisoning.
In most cases improves patient automatically after a few days, but in a small percentage of people speaking may be serious complications, such as severe drought, blood poisoning and deaths are rare and occurs most often between the have low immunity, such as children and the elderly.

May disappear these symptoms with the passage of time, provided that prove analyzes and medical examinations free patient completely typhoid and other diseases similar may heal the person of the symptoms of poisoning, but may remain pregnant for microbe for a period of time, so it is possible that occur setback and back symptoms again and that rates between 10 and 20 per cent of cases, the symptoms are more severe in the second time if reversed.

Methods of prevention of risks of salmonella infection:
Of the most important methods of prevention of this microbe is primarily for heating food probably contaminated or Albaút, and have adequate heating for a sufficient period. Because there is a discrepancy between the microbes in the elimination of heating in the sense that the heating does not destroy all the Salmonella found in food at once. Heating may kill food for 5 minutes on the highest percentage of microbes, but some remain without killing Here need for an additional five minutes. This on the one hand and on the other hand, the survival of some microbes (albeit a few) in the food after it is heated and then save it in the appropriate conditions for the growth of microbes (such as the temperature of the kitchen) for a period of time is sufficient to make the microbes grow and multiply again and cause poisoning. So it was important heating period of time to kill all the salmonella bacteria found in food. It is worth the alert here is that the likelihood of Salmonella in some food until cooked Ward because cooking methods may not be adequate or inadequate to eliminate them, Examples include scrambled eggs or fried or boiled inadequately or left after boiling for a while.

So you must store the eggs in a cool dry place and individually inside the refrigerator should also make sure that cooked eggs enough and eating dishes containing eggs after preparation directly or cooled quickly and kept refrigerated. And not stored eggs in average temperatures from 5.4 m to 0 60 m for more than two hours taking into account the removal of broken eggs and contaminated.
