well u add only 1/5 of a cup n u barely ate diz potatoes...dont worry u'll not get sick coz in case of poisoning there is an hours-to-days delay before you notice symptoms. The contaminating organism passes through the stomach into the intestine, attaches to the intestinal walls, and begins to multiply. Some organisms stay in the intestine, some produce a toxin that is absorbed into the bloodstream, and others directly invade body tissues. Your symptoms depend greatly on the type of organism that has infected you.
expired milk causes symptoms, especially diarrhea, vomiting, and stomach cramps. Diarrhea and vomiting are a normal response as the body tries to rid itself of harmful organisms.
most cases, you recover in a few days to a week as toxins are flushed from your system. You may feel weak for several days after other symptoms go away.
