Contaminated food and water, mixing with people who have contracted parasites, virus, bacteria.

Doctors rarely detect the pathogen, medications are usually required.

The best advice is to eat internationally sealed foods or foods that have a quality standard, such as bottled water and canned foods. Many of the pathogens are transmitted through meat.

After the cleanliness of the food is guaranteed also add to stay healthy...

1. Garlic: Contains allicin, a compound with antimicrobial and antiparasitic effects, potentially effective against parasites like Giardia.
2. Pumpkin Seeds: Traditionally used to treat intestinal worms, they contain cucurbitacin, which may paralyze parasites, aiding their elimination.
3. Papaya Seeds: Rich in papain, an enzyme that may break down parasitic proteins.
4. Coconut: The medium-chain fatty acids in coconut oil have antiparasitic properties and support gut health.
5. Probiotics: As mentioned, fermented foods like yogurt and sauerkraut maintain healthy gut flora, potentially crowding out harmful bacteria like E. coli or Salmonella.
6. Prebiotics: Foods such as garlic, onions, and bananas feed beneficial gut bacteria, enhancing gut health.
7. Honey: Known for its antibacterial properties, especially Manuka honey, it may help combat pathogens like E. coli and Salmonella.
8. Ginger: Contains gingerol, which has antibacterial effects and may reduce bacterial growth in the gut.
9. Turmeric: Its active compound, curcumin, has antimicrobial properties that may fight bacterial infections.
10. Vitamin C, Vitamin D and Zinc: These bolster immune function and may reduce the severity or duration of viral infections.
11. Elderberry: Contains compounds that may inhibit viral replication, particularly for respiratory viruses.
12. Green Tea: Rich in catechins, which have antiviral properties and may help prevent viruses from entering cells.

Medications...

1. Ciprofloxacin: Treats Salmonella, Campylobacter, Shigella. Protocol: 500 mg orally twice daily for 5-7 days.
2. Azithromycin: Treats Salmonella, Campylobacter, Shigella. Protocol: 500 mg orally once, then 250 mg daily for 4 days.
3. Trimethoprim-sulfamethoxazole: Treats E. coli (non-EHEC), Cyclospora. Protocol: 160 mg/800 mg orally twice daily for 3-5 days.
4. Ampicillin: Treats Listeria. Protocol: 2 g IV every 4 hours.
5. Penicillin: Treats Listeria. Protocol: 4 million units IV every 4 hours.
6. Gentamicin: Used with ampicillin or penicillin for Listeria. Protocol: 1.5 mg/kg IV every 8 hours.
7. Erythromycin: Treats Campylobacter. Protocol: 500 mg orally four times daily for 5 days.
8. Metronidazole: Treats Giardia. Protocol: 250 mg orally three times daily for 5-7 days.
9. Tinidazole: Treats Giardia. Protocol: 2 g orally as a single dose.
10. Nitazoxanide: Treats Cryptosporidium. Protocol: 500 mg orally twice daily for 3 days.
11. Doxycycline: Treats Vibrio. Protocol: 100 mg orally twice daily for 3 days.
12. Ceftriaxone: Treats Shigella. Protocol: 1 g IV once daily for 3-5 days.
13. Botulinum antitoxin: Treats botulism (Clostridium botulinum). Protocol: Administered IV as soon as possible after diagnosis.

Additional Notes:

• For E. coli infections caused by enterohemorrhagic strains (EHEC), antibiotics are typically avoided due to the risk of complications like hemolytic uremic syndrome; supportive care is preferred.
• Viral foodborne illnesses (e.g., Norovirus, Hepatitis A) and some toxin-mediated conditions (e.g., Staphylococcus aureus, Bacillus cereus) are usually managed with supportive care rather than specific medications.
• This list focuses on common foodborne pathogens; treatments for less common pathogens (e.g., Toxoplasma) exist but are typically reserved for specific cases and require medical oversight.

Tests...

It is likely a doctor prescribes a full round of anti-biotics without any knowledge.

1. Ova and Parasite (O&P), collecting a stool sample, analyzed by a human with a microscope in a lab for parasite fragments.
2. PCR, a machine process the stool sample.

Blood test...

Guiding suspicion via deficiency caused by food-borne pathogen, for instance Giardia lamblia (Parasite), chronic infection causes malabsorption of fats, impairing absorption of fat-soluble vitamins (A, D, E, K). Vitamin D deficiency can disrupt calcium regulation and parathyroid hormone (PTH) balance.

1. Hookworm (Necator americanus) – Iron deficiency anemia – Stool O&P test.
2. Fish tapeworm (Diphyllobothrium latum) – Vitamin B12 deficiency – Stool O&P test or PCR.
3. Giardia lamblia – Protein-losing enteropathy (low albumin) – Stool antigen test or PCR.
4. Cryptosporidium – Hypokalemia (from chronic diarrhea) – Stool acid-fast stain or PCR.
5. Strongyloides stercoralis – Eosinophilia – Blood serology or stool culture.
6. Taenia solium (pork tapeworm) – Vitamin B12 deficiency (rare) – Stool O&P or serology.
7. Trichuris trichiura (whipworm) – Iron deficiency (heavy infection) – Stool O&P test.
8. Entamoeba histolytica – Iron deficiency (from intestinal bleeding) – Stool antigen test or serology.
9. Ascaris lumbricoides – Protein deficiency (severe cases) – Stool O&P test.
10. Enterotoxigenic E. coli (ETEC) – Electrolyte imbalance (e.g., hypokalemia) – Stool culture or PCR.
