If dishes have come into contact with rat droppings, it is generally recommended to exercise caution and take proper steps to ensure they are thoroughly cleaned and disinfected. While washing the dishes and putting them in the oven can help reduce the risk of contamination, it's important to consider the following:
Assess the condition: Examine the dishes for any visible signs of damage or contamination. If the dishes are cracked, chipped, or porous, it may be difficult to completely remove all traces of contamination. In such cases, it is safer to discard them to avoid any potential health risks.
Thoroughly wash with hot water and detergent: Start by washing the dishes with hot water and a good-quality dish detergent. Use a scrub brush or sponge to remove any visible dirt, debris, or residue. Thoroughly rinse them to ensure all soap is removed.
Disinfect with a bleach solution: Prepare a solution of 1 tablespoon of bleach per gallon of water. Submerge the dishes in this solution for about 10 minutes to disinfect them. Rinse them thoroughly with clean water afterward.
Heat treatment: Placing the dishes in the oven at a temperature of 350°F (175°C) for at least 30 minutes can help kill potential bacteria or pathogens. Ensure that the dishes are oven-safe and won't be damaged by the heat.
Consider professional advice: If you are uncertain or concerned about the cleanliness of the dishes, it's advisable to consult with a professional cleaner or a local health department for guidance on proper cleaning and disinfection procedures.
Ultimately, the decision to keep or discard the dishes depends on several factors, including the condition of the dishes, the level of contamination, and your own comfort level with using them. If you are in doubt or concerned about the safety of the dishes, it may be safer to err on the side of caution and replace them to ensure your health and well-being.
