Food Poisoning by Staphylococcus Aureus

The true prevalence of staphylococcal food poisoning is not yet known for lots of reasons such as poor responses from the victims during the consultations with the health personnel, wrong diagnosis of the disease that may be symptomatically analogous to other forms of food intoxication like vomiting initiated by Bacillus cereus toxin, not enough collection of specimens for science laboratory investigations by means of microscopy under the microscopes such as tissue culture microscope, and inappropriate science laboratory examination.

Among the bacterial pathogens or disease-causing organism initiating foodborne diseases in America fourteen epidemics including one thousand two hundred fifty-seven cases were triggered by Staphylococcus aureus as verified through microscopy using the microscopes like the tissue culture microscope. These epidemics were followed by another eleven outbreaks or one thousand one hundred fifty-three cases in 1984, fourteen outbreaks or four hundred twenty-one cases in 1985, seven outbreaks or two hundred fifty cases in 1986, and one documented outbreak or one hundred cases in 1987. All were examined with the help of microscopy using microscopes such as tissue culture microscope.

Fatality from staphylococcal food intoxication is extremely rare although such instances have taken place among the elderly, babies and seriously debilitated individuals. Every individual is deemed to be vulnerable to this form of bacterial poisoning nevertheless, intensity of manifestations may differ. The determining procedures of the presence of the toxins are being performed with the aid of microscopy using microscopes like the tissue culture microscope. In order to determine the concentration of staphylococcal enterotoxin in foods implicated in food intoxication, the toxin must be isolated from food constituents and concentrated prior to recognition by particular precipitation with antiserum or antienterotoxin. This is performed with the aid of microscopy using a microscope such as tissue culture microscope. The two principles that are used for the purpose of determining the toxin are the selective adsorption of the enterotoxin from the extract of food onto ion exchange resins, and the utilization of physical and chemical processes for the selective taking of food constituents from the extract, leaving the enterotoxin in the solution. In the process, microscopy is being utilized with the use of a microscope. The application of these methods and concentration of the ensuing products as much as possible has made it probable to determine tiny amounts of enterotoxin in food.

There are fast methods that have been created on monoclonal antibodies, which are being assessed for their effectiveness in the identification of enterotoxins in food. These quick techniques can identify with the use of a microscope just about one nanogram of toxin for every gram of food.

One thousand three hundred sixty-four kids became sick out of an entire five thousand eight hundred twenty-four who had consumed lunch served at sixteen elementary schools in Texas. The foods were prepared in a central kitchen and delivered to the schools by truck. Epidemiological studies uncovered that ninety-five percent of the children who became sick had consumed a chicken salad. The afternoon of the day prior to the lunch, frozen chickens were boiled for three hours. After being cooked, the chickens were deboned then cooled to room temperature with a fan then grounded into tiny pieces, placed into twelve inch deep aluminum pans and stored in overnight in a walk-in refrigerator at forty-two to forty-five degrees Fahrenheit.

The next morning, the remaining ingredients of the chicken salad were mixed and the mixture was blended using an electric mixer. The food was put in thermal containers and delivered to the different schools at nine thirty to ten thirty in the morning where it was stored at room temperature until it was served at around eleven thirty in the morning to noontime. Bacteriological test of the chicken salad exposed the existence of large numbers of Staphylococcus aureus.

Infection of the chicken possibly took place when it was deboned. The chicken was not cooled quickly enough since it was placed in twelve inches deep layers pans. Development of the staphylococcus possibly happened also during the period when the food was stored in the warm classrooms. Avoidance of this incident would have involved screening the people who deboned the chicken for transporters of the staphylococcus, more quick cooling of the chicken, and appropriate refrigeration of the salad from the time of preparation to its ingestion.
