Food contaminated by pathogenic bacteria can cause various diseases such as diarrhea and typhoid. Bacterial growth in food can also result in unwanted physical or chemical changes, making the food unfit for consumption.

These results indicate that the total plate number value in these samples is higher than SNI 7388: 2009 which is < 1x102 colonies/g.
