Running a hot dishwasher cycle can help sanitize dishes and reduce the risk of microbial contamination, including the potential presence of parasites and their eggs. However, it's important to note that dishwashers are not specifically designed to kill or eliminate all types of parasites or their eggs. Some parasites, such as certain types of protozoa or helminths, may have resilient forms or stages that can withstand the temperatures typically reached in a dishwasher.
To ensure proper sanitation, it is generally recommended to follow these guidelines:
Pre-rinse: Remove any visible food particles from the dishes before placing them in the dishwasher. This helps ensure a more effective cleaning process.
Use hot water: Set your dishwasher to the highest temperature setting available. Most dishwashers reach a temperature of around 130 to 170 degrees Fahrenheit (55 to 75 degrees Celsius) during the wash and rinse cycles, which can help in reducing microbial contamination.
Use a dishwasher detergent: Use a high-quality dishwasher detergent that is effective in removing food residues and microbial contaminants. Look for products that have been tested and proven to provide proper sanitation.
Load dishes properly: Arrange the dishes in a way that allows proper water circulation and coverage during the cleaning process. This ensures that all surfaces come into contact with the hot water and detergent, improving the chances of effective sanitation.
While a hot dishwasher cycle can help reduce the risk of contamination, it may not provide a guarantee of complete elimination of all parasites or their eggs. If you have concerns about the dishes being contaminated with parasites, especially if they have been in contact with animals, it may be prudent to take additional measures such as thorough handwashing, using separate dishware for animals, or considering alternative cleaning methods specifically designed for parasite elimination.
