Present state of knowledge on staphylococcal intoxication

Area of Science:

• Food microbiology
• Food safety
• Public health

Background:

• Staphylococcal intoxication is a prevalent global foodborne illness.
• Staphylococci bacteria are frequently found in raw animal products, necessitating robust food processing.
• Human carriers are a significant source of post-processing contamination.

Purpose of the Study:

• To review the epidemiological factors of staphylococcal food poisoning.
• To analyze the impact of the food environment on staphylococci survival, growth, and enterotoxin production.
• To evaluate control measures for preventing staphylococcal food poisoning.

Main Methods:

• Literature review focusing on epidemiological data.
• Analysis of intrinsic food properties (pH, water activity, etc.).
• Evaluation of extrinsic processing and storage parameters (temperature, irradiation, etc.).

Main Results:

• Enterotoxins produced by staphylococci are highly resistant to food processing methods.
• While staphylococci can be eliminated, their heat-stable enterotoxins often survive.
• Most food environments support staphylococcal growth and enterotoxin formation.

Conclusions:

• Effective food processing is crucial to minimize staphylococci in raw foods.
• Preventing recontamination by humans is essential for food safety.
• Rapid cooling, refrigeration, and education are key to preventing staphylococcal food poisoning.
