Household hygiene: Common items identified as high bacterial risks

Common household items often harbor more bacteria than toilets, according to hygiene and microbiology experts. High-risk items include kitchen sponges, which can host up to 54 billion germs per square centimeter, and reusable grocery bags that may carry residue from raw meat or soil.

To prevent cross-contamination, experts recommend specific cleaning routines. Kitchen towels should be replaced daily if they remain damp, or at least every two days if they dry out, as bacteria can multiply rapidly in moist environments. It is advised to use separate towels for hands and dishes to avoid spreading pathogens like E. coli or Staphylococcus aureus.

Other frequent touchpoints requiring regular disinfection include refrigerator handles, smartphones, remote controls, and cutting boards. Cutting boards with deep scratches should be replaced to prevent germ buildup, and coffee machine reservoirs and water bottles should be cleaned regularly to prevent mold and yeast growth.
