Definition check — Bacterial food intoxication: Which statement correctly describes this category of foodborne illness?

Difficulty: Easy

Correct Answer: Food-borne illness caused by the presence of a bacterial toxin formed in the food

Explanation:


Introduction / Context:
Clear definitions are essential in food safety. ‘‘Food intoxication’’ differs fundamentally from ‘‘food infection’’ in etiology, incubation period, and control strategies.



Given Data / Assumptions:

  • ‘‘Intoxication’’ implies toxin is preformed in food before consumption.
  • Common examples: Staphylococcus aureus enterotoxin, botulinum neurotoxin.



Concept / Approach:
In intoxications, ingesting the toxin is sufficient to cause illness; viable bacteria need not be present or multiply in the gastrointestinal tract. In infections, pathogens must be alive and proliferate in the host.



Step-by-Step Solution:
Compare statements: (a) describes infection; (b) defines intoxication.Select (b) as the precise definition of bacterial food intoxication.



Verification / Alternative check:
Outbreak timelines often show very short incubation for intoxications (e.g., 1–6 hours for staphylococcal enterotoxin) consistent with preformed toxin exposure.



Why Other Options Are Wrong:

  • (a): describes food infection, not intoxication.
  • (c): cannot be both simultaneously as the definitions are distinct.
  • (d): incorrect because (b) is correct.



Common Pitfalls:
Using ‘‘poisoning’’ loosely without specifying whether toxin was preformed (intoxication) or produced in vivo (toxicoinfection).



Final Answer:
Food-borne illness caused by the presence of a bacterial toxin formed in the food
