Giardiasis is an intestinal infection caused by the parasite Giardia lamblia, often associated with contaminated water sources. To prevent giardiasis, utilizing an approved water supply is crucial. This means using water that has been treated and tested to ensure it is free from harmful pathogens, including Giardia. Consuming untreated or poorly treated water from rivers, lakes, or wells that could be contaminated with feces is a primary risk factor for the transmission of this illness.

The other options, while they may relate to food safety practices, do not directly address the specific measures necessary to prevent giardiasis. For example, cooking with additives or purchasing pork from approved suppliers are relevant to other foodborne illnesses and overall food safety but do not impact the risk of contracting giardiasis. Similarly, using Grade A pasteurized milk is important for preventing illnesses associated with milkborne pathogens but is not specifically relevant to preventing giardiasis. Thus, ensuring a safe and approved water supply is the most effective preventive action against this particular parasite.
