Coagulase positive Staphylococcus

Category Microbiology Laboratory
Test Coagulase positive Staphylococcus

Also referred to as Staphylococcus aureus test. Foods that are frequently incriminated in staphylococcal food poisoning include meat and meat products; poultry and egg products; salads such as egg, tuna, chicken, potato, and macaroni; bakery products such as cream-filled pastries, cream pies, and chocolate éclairs; sandwich fillings; and milk and dairy products. Foods that require considerable handling during preparation and that are kept at slightly elevated temperatures after preparation are frequently involved in staphylococcal food poisoning.

Staphylococci exist in air, dust, sewage, water, milk, and food or on food equipment, environmental surfaces, humans, and animals. Humans and animals are the primary reservoirs. Although food handlers are usually the main source of food contamination in food poisoning outbreaks, equipment and environmental surfaces can also be sources of contamination with S. aureus. Human intoxication is caused by ingesting enterotoxins produced in food by some strains of S. aureus, usually because the food has not been kept hot enough (60°C, 140°F, or above) or cold enough (7.2°C, 45°F, or below). Therefore, this is a good test to indicate temperature abuse of selected food products.


Results are reported in CFU (colony forming units) per unit analyzed. A confirmation charge may be incurred in cases of Presumptive Positive screens. 50g minimum sample is recommended. Environmental surface samples can also be analyzed.
