Thank you for your query at DoctorSpring.com
I really appreciate the fact that you're so concerned about the community. Yes if possible you can notify the manufacturer since it can be a common source of infection for a lot of people. But giving stool sample as of now is not required.
From your description, it typically fits acute gastroenteritis. The fact that you don't have fever is also encouraging.
I will advise you to keep yourself adeqautely hydrated till the symptoms subside and it will be prudent to start medication for the same.
I advise the following :
1) Tab. Loperamide SOS ( to control diarrhea, can be taken every 6 hours if required )
2) Tab. Ciplox 500 mg twice daily for 3-5 days depending on the severity of your symptoms.
3) Cap. Omeprazole 20 mg once daily before breakfast for 3-5 days. ( if the burping continues )
4) Probiotic capsules/ supplements like curd fortified with probiotics.
Please have bland food till your diarrhea frequency is controlled.
Feel free to discuss further,
