Answer 1

The black powder or white discs found floating on the pickle or murabba on opening the jar after a long time is nothing but mold and yeast or fungus. Food items which are found with molds or fungus should not be consumed. On eating such food items one may experience food poisoning, stomach cramps, nausea and vomiting.
