[Health Channel/Comprehensive Report]Tables and chairs at home are often in contact with human body, food and other objects, and are easily contaminated by bacteria, viruses and other pathogenic microorganisms. What’s more, when coughing or sneezing, many germs are directly sprayed on the surface. Physicians pointed out that human skin, mouth and nose, food and drink residues, animal hair and dander, and microorganisms in the air are all common sources of pollution. Tables and chairs should be cleaned regularly and good personal hygiene habits should be maintained to reduce the chance of bacterial growth.
Human bacteria will be transferred by contact
Huang Xuan, a thoracic and intensive care specialist, posted on his Facebook page “Dr. Huang Xuan Dr. Ooi HeanThe article stated that the following common bacteria and other microorganisms may exist on the skin, mouth and nasal cavity of the human body. When touching tables and chairs, these microorganisms may be transferred to the surface of the object:
Please read on…
1. Staphylococcus aureus: Common bacteria that live on the skin and in the nasal cavity.
2. Enterococcus: Bacteria present in the human gut and possibly also on the skin and mouth.
3. Candida albicans: Common yeast found in the mouth and other moist areas.
4. Acne bacteria: Common bacteria found on the skin, especially in the sebaceous glands associated with acne.
In addition to the above, he stated that there are other bacteria and microorganisms such asStaphylococcus epidermidis、Lactobacillus acidophilusand various oral flora in the oral cavity. But everyone’s skin and oral microflora are different and influenced by lifestyle habits, environment and individual differences. Therefore, different types and concentrations of microorganisms may exist in different populations.
Food residues are easy to breed bacteria
“Food crumbs are a paradise for all kinds of bacteria!” Huang Xuan pointed out that food and drink residues may drip or splash onto tables and chairs and cause pollution, such as drinks, soups, sauces, salad dressings, grease, vinegar, tomato paste etc., may drip onto tables and chairs; food residues and debris, such as bread crumbs, potato chip fragments, vegetable or fruit residues, etc., may also fall on the surface of tables and chairs, causing pollution.
Animal hair and dander become bacteria transmission channels
Huang Xuan reminded that if there are pets at home, the hair and dander may be attached to the tables and chairs, and various microorganisms may be attached to the hair and dander. The degree of cleanliness and individual differences vary:
1. Canine and feline microorganisms:A variety of bacteria and fungi can be present on pet hair and dander, such as the common Staphylococcus aureus and Staphylococcus intermedius, as well as fungi such as Aspergillus and Candida.
2. Infectious skin pathogens:Some infectious skin pathogens such as mites (such as canis mites) or fleas (such as fleas) may be carried on the skin of pets.
3. Hypersensitivity:Some people are allergic to pet hair and dander, which may be related to allergens in pets, such as mites in cats (Fel d 1) and mites in dogs (Can f 1).
Airborne microbes will attach to surfaces
Huang Xuan pointed out that airborne microorganisms, such as bacteria and fungal spores in dust, may adhere to the surface of tables and chairs, although the actual situation may vary depending on the home environment, geographical location and other factors. The following are common bacteria and fungi:
1. Pseudomonas aeruginosa: Common pathogens found in soil, water, plants and animals. May be attached to tables and chairs through airborne dust, especially if proper cleaning and hygiene measures are lacking.
2. Escherichia coli: Bacteria commonly found in the intestinal tract, which can be present from food residues or poor hygiene, and can also be present in dust.
3. Mold:Dust may contain a variety of mold spores, which can spread through the air and attach to the surfaces of tables and chairs.
6 steps to clean tables and chairs correctly
According to Huang Xuan, tables and chairs can be properly cleaned through the following steps:
1. Remove surface debris:Use paper towels or cleaning cloths to remove large garbage, food residues and other debris from the tables and chairs, and do not put them on the tables and chairs.
2. Appropriate use of cleaning agents:Choose the appropriate cleaning agent according to the material of the table and chairs. Generally, according to the safety instructions of the cleaning agent, using a cleaning agent containing disinfectant ingredients can effectively kill bacteria and viruses.
3. Wipe the surface:Use a damp cloth or paper towel to take an appropriate amount of detergent and wipe the surface of the table and chair, including hidden corners.
4. Pay attention to hidden areas:For example, the edges and corners of the table, the crevices of chairs, etc. are prone to accumulation of dirt and bacteria, which can be cleaned with a brush or small tools.
5. Regular cleaning:Regular cleaning is recommended, especially for frequently used areas such as dining tables and desks. The frequency depends on the frequency of use and the environment, but it is recommended to use at least once a day or once a week.
6. Personal Hygiene:In addition to cleaning the tables and chairs themselves, personal hygiene is also important. Washing your hands frequently can reduce the possibility of spreading germs to tables and chairs, and ensure that family members maintain personal hygiene, especially after eating or drinking or touching items that may contain contaminants.
Huang Xuan emphasized that after eating, food residue should be removed in time to reduce the chance of bacterial growth, and the home environment should be kept clean, including floors, windows and other surfaces, to reduce bacteria and germs.
