Wataalam wanashauri kubadilisha sifongo jikoni kila siku

Wataalam wa afya wanasema kifaa cha kuoshea vyombo jikoni kinapaswa kubadilishwa kila siku ili kuzuia vijidudu hatari. Uchunguzi uliofanywa na wanasayansi umeonyesha kuwa sifongo zinaweza kukusanya bakteria hata baada ya kusafishwa vizuri. Hii inaweza kusababisha matatizo kama sumu ya chakula na homa ya matumbo.

Kwa mujibu wa wataalam, sifongo zinazotumika kuoshea vyombo jikoni ni chanzo kikubwa cha vijidudu hatari. Uchunguzi uliofanywa na wanasayansi, chini ya uongozi wa Dkt Primrose Freestone, mtaalamu wa sayansi kuhusu vijidudu hatari kiafya, ulichunguza sifongo zilizotumika kwa vipindi tofauti, kuanzia siku moja hadi miezi mitano. Sifongo hizo zilisafishwa mara kwa mara kwa kutumia kemikali za kuua vijidudu, lakini matokeo yaliona bakteria kadhaa zilizobaki baada ya saa 14 tu, hata baada ya kuosha kwa sabuni ya kuua vijidudu na maji moto.

Sifongo iliyotumika kwa siku tatu ilikuwa na bakteria nyingi, na zile zilizotumika kwa miezi miwili hadi mitatu ziliashiria idadi kubwa ya vijidudu. Wataalam wanasema kuwa aina yoyote ya vijidudu hatari jikoni, ikiwa ni pamoja na vinavyosababisha sumu ya chakula, homa ya matumbo, na vijidudu visivyosikia dawa za antibiotics, vitaingia kwenye sifongo. "Sifongo sio ghali na ushauri wangu ni kuzibadilisha kila siku," alisema Dkt Freestone.

Ikiwa sifongo inatumika kuosha mboga chafu au nyama mbichi, inashauriwa kuitupa mara moja baada ya matumizi. Baadhi ya watu wameanza kutumia brashi badala yake, ambazo wanasayansi wanasema ni safi zaidi, lakini brashi pia zinaweza kukusanya vijidudu baada ya muda. Ushauri huu unasisitiza umuhimu wa usafi nyumbani ili kuhakikisha afya bora ya familia.

Researchers at the University of Cambridge have found that 168 common industrial and agricultural chemicals can harm beneficial bacteria in the human gut, with some also promoting resistance to antibiotics. Drawing on a large laboratory screen, the team created a machine learning model to predict which chemicals may pose risks to the microbiome.

Researchers at the University of Cambridge report that 168 widely used industrial and agricultural chemicals slowed or stopped the growth of bacteria commonly found in a healthy human gut in laboratory experiments, raising questions about whether routine chemical exposure could affect the microbiome and, in some cases, antibiotic resistance.

Street food provides unique cultural experiences during travels, but it carries risks of gastrointestinal illnesses, with the WHO reporting that one in ten people falls sick yearly from contaminated food and 420,000 die from it. Food safety and travel experts recommend three key steps for safe enjoyment: follow locals or join tours, watch for hygiene red flags, and be cautious with water.

Mexico's Federal Consumer Protection Agency (Profeco) and the FDA recommend refrigerating eggs to prevent Salmonella contamination and extend freshness. While many leave them at room temperature, cold storage reduces food poisoning risks. The ideal spot is in a constant-temperature area, not the fridge door.

Residents in Visby and surrounding areas are urged to continue boiling drinking water after parasites Giardia and Cryptosporidium were detected in the municipal supply. The recommendation was introduced in early December and is expected to remain in place over Christmas and likely until the end of January. The parasites can cause stomach illness and diarrhea.

Researchers at Nagoya University report that two common gut microbes can work together to break down the colon’s protective mucus layer, leaving stool dry and difficult to pass—an effect that standard laxatives may not address. The team also found higher levels of these bacteria in people with Parkinson’s disease, who often experience constipation decades before motor symptoms, and showed in mice that disabling a key bacterial enzyme prevented constipation.

Recent research has cast doubt on alarming claims about microplastic ingestion, such as consuming a credit card's worth weekly. While microplastics are widespread in the environment and human tissues, studies suggest exposure levels are far lower than feared, and health impacts remain unclear. Experts urge caution until more rigorous data emerges.
