It's important to keep your kitchen clean to guard against bacteria growth and prevent other organisms from "moving in." Here are a few tips:

• Wash counters and sinks with hot water and soap. Sanitize the counters and sinks to kill any lingering bacteria. Use a freshly made solution of one teaspoon chlorine bleach in one gallon of water as a sanitizing solution. Be sure to keep it and all cleaning supplies away from food.
• Clean up crumbs or spilled liquids right away, and mop the kitchen floor at least weekly.
• Use paper towels or cloth dishtowels that are frequently washed rather than sponges, which can hold and spread bacteria.
• Do not leave out food, garbage or dirty dishes.
• Clean the refrigerator out once a week so condiments, leftovers and other items won't "linger" too long. Wipe down the refrigerator with hot soapy water or the age-old combination of a cup of white vinegar to one gallon of water, which naturally cleans, prevents mold and deodorizes. Consider keeping an opened box of baking soda in the refrigerator to fight odors.
• Check for leaks or dampness under the sink and make repairs to reduce moisture.
