"Due to Thailand's location in a tropical zone, the climate is hot, making ice a popular product among consumers. Ice is used to cool down and relieve heat by mixing it with various beverages or consuming it directly. Examples include clear ice, ice in sweet drinks, and blended fruit ice. Although ice is highly favored, there is also a high risk of contamination. Ice has a high likelihood of being contaminated with a significant amount of bacteria (Sanchai Yodmani, 2012)."
