How often should I wash my washcloth? It's late at night after a busy day, and you're nearly ready for bed. Before you head off to sleep, you might use a washcloth on your face to wipe away the day's accumulation of dirt and oil or your makeup. While this essential step can help prevent skin problems, if the washcloth itself isn't clean, you might defeat the purpose by introducing new germs to your face. Neglecting to clean your washcloth on a regular basis can cause the towel to become a breeding ground for bacteria and mold. Whether you use a washcloth only for your face or on your entire body, using a clean cloth will help combat the germs living in bathrooms. Bathrooms -- which are typically wet, warm spaces -- are the perfect environment for bacteria and mold. Letting your damp washcloth lie around for days invites bacteria and mold, and you can unknowingly spread bacteria if you reuse the same cloth again and again. The point of bathing is to get rid of bacteria -- not to add more to your body.

Evolving Bacteria | ICR - That's a Fact

Does the five second rule really work? You can almost taste the last chocolate truffle in the box. As you raise it to your lips, your mouth begins to water with delicious anticipation. And then -- oops! It slips out of your hand and lands (along with your sweet expectations) on the floor. But it's still intact. Do you a) apply the five second rule, pick up it, dust it off and eat it or b) throw it in the trash and head to the store for another box? If you picked the second option, congratulations!!! You've just avoided consuming something covered with thousands of germs. If you picked choice A, however, you may be interested to know that the five second rule (no doubt invented by a kid eager to enjoy the last bite of his fallen Hershey bar) is a dirty little lie.

FOOD SAFETY: Seafood: Like raw meat, raw seafood may contain bacteria that can be destroyed only by cooking. Some seafood may also contain toxins such as mercury which may be harmful for young children or an unborn baby.

Canned foods often contain a tremendous amount of salt because bacteria are much less likely to thrive in high salt environments. This allows foods to have a long shelf life but, unfortunately, exposes people to very high sodium levels in their foods. Try to avoid canned foods as much as possible, particularly if you have high blood pressure and are trying to limit your salt intake. Do not eat food that comes from a damaged can. Cans that have bulges in them are generally full of gas-producing bacteria that has caused the can to get ‘bent out of shape.’ Throw out any can that looks suspicious. If you choose to can your own food, take seriously the admonition that the jars and tops must be boiled in advance of beginning the canning process. This eliminates bacteria from the jars and makes it less likely your product will end up making you sick. Use approved old-school Bell jars, and make sure they seal properly.

FOOD SAFETY: Chicken and Other Poultry: Poultry may contain harmful bacteria such as salmonella, listeria, and campylobacter. Washing chicken and other poultry does not remove bacteria. You can kill these bacteria only by cooking chicken to the proper temperature.

Essentially fermented cabbage, sauerkraut contains lactobacilli plantarum that can do wonders for your immune system. It also has the ability to reduce the growth of detrimental yeasts and is one of the best nondairy sources of probiotics you can eat.

A recent study looked at rats eating a diet high in pectin, a component of the dietary fiber in apples. When compared to rats on a normal diet, the rats with the apple-rich diet had increased amounts of beneficial bacteria. Although researchers aren't sure if apples will have the same effect in humans, investigators did conclude that by eating apples regularly, the friendly bacteria "help produce short chain fatty acids that provide ideal pH conditions for ensuring a beneficial balance of microorganisms."

This thick and creamy beverage contains a mixture of beneficial yeasts and bacteria, making the drink rich in probiotic cultures. Containing 10 types of active microorganisms, kefir offers more probiotics than other more common fermented dairy products, like yogurt or buttermilk.

FOOD SAFETY: Fresh Fruits, Vegetables, and Juices: Fresh produce may come in contact with harmful bacteria from many sources, from contaminated soil and water in the fields to a contaminated cutting board in the kitchen. Fruit and vegetable juices must be treated to kill bacteria.
