The American telecommunication network CNN reported before that because of worrying that the bathroom is full of bacteria, most people are diligent in cleaning, and other places may be ignored. Kitchen is the case. Charles Gerba, a professor of public health, environmental science and immunology at the University of Arizona, pointed out that the place with the most bacteria in the home is actually a kitchen.

But when cleaning a kitchen, many people only use the control desk, desktop, and slim down a sink, ignoring many places that are prone to hiding dirt. Here are 10 small places and items that are often overlooked for cleaning in kitchens, where bacteria are the most dense, but you may never have thought about cleaning them. It is included in the regular cleaning project so that the kitchen will not be dissipated and bacteria will grow.

1.Shuilong Head Holder

We often rush to the kitchen sink, but the waterlong Head Holder is often ignored. The U.S. Department of Agriculture pointed out that sinks are the main temperature beds of foodborne bacteria, such as the slaughtering bacteria. When we process raw meat such as pork, beef, chicken, etc., the surface of the meat may contain stool bacteria from the slaughtering process. And after we touched the raw meat, the first thing we grabbed was the water dragon's head handle.

Cleaning method: In most cases, just scrub with soap and water.

2. Sink drainage holes and filter network

If the food residue is stuck and accumulates, it will easily cause odor and breed bacteria.

Cleaning method: Remove and scrub every week, and occasionally wash with hot water or sausage + vinegar.

3. Refrigerator Handle

A study found that refrigerator handles are one of the places with the most bacteria in kitchen items, including medica sinensis, Staphylococcus aureus and chains. Because I often turn off the refrigerator when I cook and use ingredients, I may find that I forgot what to take after processing a certain item of food, so I go back to open the refrigerator, and I usually don’t wash my hands during this process. Many people also hang towels on the refrigerator handles that have been wiped and dyed kitchens.

Cleaning method: Just spray with a multi-purpose cleaning agent and scrub it, do it at least once a week.

4. Refrigerator fresh pump

According to research by the National Health Foundation of America, the two places with the most bacteria in kitchens are vegetable pumping and meat pumping, which may include sedum, listeria, melanobacteria, yeast and bacteria. The frequency should be maintained at least once a month and the refrigerator should be kept at about 5 degrees Celsius to reduce bacterial growth.

Cleaning method: Remove the pump from the refrigerator and scrub with a gentle cleaning agent dipped in sea mattress or cloth.

5. The microwave oven interior, handle, and touch panel

Microwave oven is a good helper for quick heating of dishes, but when food is heated, it will occasionally spray grease and slag on the inner wall. If it is cleaned from time to time, it will not only cause doubts, but also cause easy damage.

Cleaning method: You can use microwave oven and heat a cup of water to steam the broken food residue. And scrub with moisturizer, lemonade or cleaner.

6. Oil and smoke filter network

Many people may rub the oil and smoke machine and gas tank after cooking, but the filter network rarely cleans. Filtering the oil and scale accumulation in the Internet, the efficiency of oil absorption smoke will become worse, and bacteria will be hidden.

Cleaning method: Remove and wash once a month, and you can use hot water + dishwashing essence + small su to make foam and wash. In addition, many pumping machine companies now have regular filtering services, which should be used and updated regularly.

7. The oven or microwave oven, or the pump rack placed in the oven, is rarely cleaned. There may be a lot of food slags, which may easily lead to worms and cockroaches.

Cleaning method: Use a vacuum cleaner to suck the food residue under the oven clean. Pull open the pull-up rack and wash with soap and water.

8. The body and mouth of the flavoring pot

We often cook one side and use the flavoring pot to taste the flavoring pot, so the bacteria content on the surface of the outer layer of the flavoring pot is also very high.

Cleaning method: Scrub with soap and hot water, and be careful to dry until it is finally put back on the rack.

9. Seaweeds, rags

A study in 2017 found that 362 different bacteria can be found in the seaweed in the kitchen, and 82 billion bacteria are found in a cubic inch of seaweed.

Many people are used to wipe the rag and then put it on the control table without washing it. Some of them are rags that have been used for a long time but are not eliminated. Poison expert Professor Zhao Mingwei once wrote an article pointing out that research has found that if the rag is not washed for a long time, the total number of bacteria on a single rag can reach 500 billion! As long as you hear the smell of the rag, it means that bacteria are beginning to grow. It is recommended that you change the rag once a month, and it is best to use a wood-fiber material, which has strong water and oil discharge properties, making it less likely to allow bacteria to adhere to it.

Cleaning method: After using sea mattresses and rags, they must be cleaned, dried, and then slid. And it should be replaced regularly, and do not use it for more than one month.

10. A survey on the back and gaps of the cutting board shows that the amount of stool bacteria on the cutting board is more than on the bucket seat, because the cutting board used for cutting meat is prone to retain Salmonella and Madrenia. After using up the cutting board, people usually only clean the front of the cutting board, and often forget to remember or ignore cleaning on the back and gaps.

Cleaning method: brush both front and back, and regularly use hot water or salt water to kill bacteria.
