7 Headaches
This symptom may range from mild to severe and most patients suffer it several times a day or constantly. The patient can usually control the headaches with common painkillers.
8 Botulism
This is the most dangerous kind of food poisoning. It is produced by the Clostridium Botulinum bacteria and can even produce neurological symptoms.
In addition to all the symptoms mentioned above, the patient usually suffers from blurred vision, difficulty speaking, muscle weakness (that can affect the diaphragm or respiration muscles) which causes difficulty to swallow and breathe, and in extreme circumstances muscle paralysis (in this case, it occurs from the head down through the body).
