Welcome to the Food Borne Disease Site. The sources of the foodborne illness pathogens are ubiquitous. Food and food products will always be contaminated with low levels of pathogens. At low levels, pathogenic microorganisms cause no problems. At illness thresholds, however, they can make people ill and cause death.

Staphylococcus aureus in food

Staphylococcus aureus is one of the most successful human pathogens, with global distribution and the potential to cause, potentially fatal disease.

Staphylococcus aureus may be present in virtually any food because it can reproduce within wide ranges of temperature, acidity and salt content.

The organism is well-arm with potent virulence factors, survival fitness, and antimicrobial resistance determinants. The largest numbers tend to be found near openings to the body surface such as the anterior nares, axillae and the inguinal and perineal areas. It has tremendous capacity to cause harm when an opportunity such as wound or weakened immune system presents itself.
In addition, Staphylococcus aureus produces a wide range of virulence factors – proteins that help the bacteria sustain an infection and damage human host cells.

The main sources of staphylococcal contamination are food handlers and contamination typically occurs after heat treatment of the food. The two most important causes to foods are nasal carriers and individuals whose hands and arms are inflicted with boils and carbuncles, who are permitted to handle foods.

Commonly identified sources of Staphylococcus aureus foodborne illness include red meats and sausages; cheeses; cream-filled pastries; milk; dairy product; and salads made with chicken, mayonnaise, pasta with tomato sauce, egg, tuna and macaroni.

Staphylococcus aureus can be transferred from the mouth to food via the spoon. If the spoon is left for some time at a warm temperature the bacteria will grow, multiply and produce toxin.
