MANILA - Where there's water, there are bacteria. But it does not have to be in a bathroom or swimming pool. A bowl of soup left in the kitchen can also be the culprit.

"Ang soup, mataas ang water activity. Ang mga mikrobyo, gustong-gusto nilang tirahan ang mga ganito," said microbiologist Dr. Windell Rivera.

Rivera added that bacteria can easily multiply in a soup, especially when left in room temperature for a couple of hours.

"Millions of bacteria will be able to grow sa broth [sa pag-iinit]. Puwede mong mapatay 'yung iba pero kapag spore former bacteria 'yung nandoon, dadami pa sila," he said.

Cleaning up in the kitchen also has its risks. Once bacteria find their way to a kitchen sponge, it may lead to cross-contamination.

"Mako-contaminate sila ng food poisoning agents, tulad ng Salmonella, E. coli na magdudulot ng vomiting, diarrhea o fever sa tao after a few hours," Rivera explained.

He said the public also need to be on the lookout against the bacteria Bacillus Cereus and Clostridum which cannot be neutralized even if we re-heat our soup.

"Kung na-contaminate na ang lalagayan ng soup, kailangang malinis itong mabuti gamit ang dishwashing liquid na may antibacterial component," Rivera added.
