The symptoms of food poisoning can vary based on the contaminant and individual susceptibility. Generally, symptoms manifest within a few hours to several days after consuming the contaminated food or beverage. The most prevalent signs include:

Gastrointestinal Distress: Nausea, vomiting, diarrhea (which may be bloody), and stomach cramps are classic indicators.
Systemic Symptoms: Fever, headache, and general weakness may also occur.
Neurological Symptoms: In rare, severe cases, food poisoning can affect the nervous system, leading to blurred vision, muscle weakness, tingling, or numbness.

1.2 Timing of Symptoms

The onset of symptoms varies widely depending on the type of contaminant. Here are some examples:

Bacillus cereus: Symptoms appear rapidly, within 30 minutes to 15 hours, commonly from rice or leftovers left at room temperature.
Salmonella: Symptoms may take 6 hours to 6 days to manifest, often linked to poultry, eggs, and dairy products.
Norovirus: Symptoms typically begin 12 to 48 hours after exposure, frequently from shellfish or ready-to-eat foods handled by infected individuals.

Understanding these timelines can help pinpoint the possible source of contamination.

2. When to Seek Medical Attention

While most cases of food poisoning resolve on their own, certain situations warrant immediate medical attention. Knowing when to see a doctor can prevent severe complications.
