If food poisoning is mild, vomiting, gastrointestinal discomfort, dizziness, you can relieve yourself without seeing a doctor. If it is serious, it will lead to foaming at the mouth and coma. Must be rescued by the hospital. If the hospital treats you, there will definitely be a test report. Toxic substances can definitely be used as evidence to call the police. Judging from your suspicion, there should be no big problem. I didn't see a doctor, so there was no result. But you think the symptoms persist. I suggest you go to the hospital for laboratory tests to avoid delaying your illness (⊙o⊙). If it is chronic poisoning, it should be treated as soon as possible (⊙o⊙).
