Bacteria are everywhere. They are unavoidable. No matter how clean an area is, a certain number of bacteria are likely to grow on almost any surface, and that’s not necessarily a cause for concern, with certain germs in small doses. Some of these microorganisms are even good for us—take, for example, the probiotic microbes that promote a healthy digestive tract and boost the immune system. However, some are pathogens, meaning they can cause disease. The presence of these bacteria facilitates the spread of colds, the flu, and other illnesses. As a result, awareness of where these germs live and thrive and how to combat them is essential to maintaining the healthy home that you and your loved ones deserve.

A Scientific Study on Bacteria

A recent study conducted by NSF International tested 22 households and discovered a variety of bacteria, everywhere from the floors and walls to the sink and countertops, and most places in between. The majority of the germs discovered were harmless. Their study also revealed that homes with pets tend to contain more diverse species of bacteria as well as those located in suburban neighborhoods. Water leaks were found to produce a high level of fungi. Refrigerator doors and toilet seats were two of the most popular surfaces for bacteria to thrive.

Common Kitchen and Bathroom Bacteria Locations

We’ve established that germs are everywhere, but realistically, we cannot clean every spot on every surface of our homes. That’s why it’s good to know the most common places where illness-causing microorganisms live. Here are the top five, according to Today.com.

  • The kitchen sponge: Bacteria love moisture, especially the coliform bacteria. Kitchen sponges and bacteria go hand-in-hand. It has been found that as many as 15% of kitchen sponges also contain salmonella.
  • The kitchen sink: This area is germ-filled. With raw meat rinsed and residue of multiple other food items deposited, living organisms enjoy the wet environment here.
  • The cutting board: This surface comes in contact with plenty of food sources, including raw meat, so expect germs to reside on this surface.
  • The refrigerator door handle: With possibly the most popular door handle of the house, the fridge gets opened and closed multiple times per day in most homes. With all these touches and occasional sponge swipes, this spot is a breeding ground for E. coli, salmonella, and other pathogens.
  • The kitchen counter: This surface sees a lot of action, with food prep and the like, in addition to plenty of food and drink spills, splashes from the dirty kitchen sink, and contact with the kitchen sponge.

 Clearly, bacteria in the kitchen is a common challenge. But the kitchen is not the only breeding ground for nasty bacteria to thrive.

Bathroom areas are also popular places for bacteria to grow as well, and it’s not just the toilet seat. Just like in the kitchen, the counters and the sink are problem areas. As bathroom sink bacteria splash onto countertops, the toothbrush holder and toothbrushes easily become infected too.

How to Eliminate These Bacteria in Your Home

All this germ talk can feel overwhelming, but it doesn’t have to be. Tackling the tough areas of your home requires a little planning and a commitment to maintenance. Start by surveying where the highest traffic areas are in your home. Keep those surfaces clean with vacuuming, sweeping, and where appropriate, soap and warm water. For surfaces that can tolerate it, including the toilets, a quick disinfectant can be made with one cup of bleach in a gallon of water and used to kill germs on the spot.

Then it’s time to attack those top five mentioned earlier:

  • Kitchen sponges and dishcloths should be soaked in a diluted bleach solution of 3/4 cup bleach per one-gallon water two or three times a week.
  • The cutting board should be scrubbed with warm soapy water after each use and allowed to air dry before being put away. For extra precaution against bacteria, pour a highly diluted bleach-water mixture over the surface and pat dry with a towel.
  • Wash the kitchen sink bacteria away with hot soapy water after each use and wipe down with an antibacterial wipe once a day.
  • Since sponges are the main method for how bacteria spread in the kitchen, you can cut down on sponge contamination by using paper towels to wipe down spills.
  • Wipe down kitchen counters and the refrigerator door handles once daily with antibacterial wipes as well.

What is the common denominator for most germ contamination? Well, it’s primarily human handling. So, don’t forget to wash your hands often to minimize transfer to other areas of the house and the bacteria entryways into your own body. Every time you touch your face with dirty hands, you are at risk of infecting yourself with dangerous pathogens.

Quartz Surfaces by Caesarstone

One of the greatest benefits of updating to quartz surfaces throughout your home is their ease of maintenance. Many Caesarstone surfaces require little more than a soap and water wipe down to remain clean and beautiful. To kill germs, simply follow up with a soft cloth and non-abrasive gel cleanser with bleach. Caesarstone finishes other than Polished may require increased daily maintenance. Visit the Caesarstone Care and Maintenance page to download the Caesarstone Care Guide.

Even the most difficult spills, from nail polish to red wine, are a cinch to remove with Caesarstone. The nonporous surfaces will not hold onto bacteria the way other porous surfaces (like granite and marble) do, and germs can be wiped away easily and quickly with little daily attention. Explore all the high-quality quartz collections by Caesarstone.

HFMA’s new chair is a hospital CFO as Medicare reporting gets more detailed and revenue cycle work gets more technical

HFMA’s new chair is a hospital CFO as Medicare reporting gets more detailed and revenue cycle work gets more technical

HFMA named Corewell Health CFO Matthew E. Cox as its national chair effective June 1, 2026, while elevating revenue cycle and reimbursement leaders to its board, according to HFMA’s GlobeNewswire announcement. The association’s own coverage of CMS’s FY 2027 IPPS/LTCH PPS final rule summary and new Medicare cost-reporting requirements such as Worksheet S-12 indicates a compliance workload that is increasingly data- and documentation-heavy for hospital finance and reporting teams. In parallel, HFMA’s certification catalog, including the Certified Hospital Cost Report Specialist (CHCRS) and Certified Specialist Payment & Reimbursement (CSPR), points to how health systems are professionalizing the skill sets needed to operationalize reimbursement policy changes. For operators, the practical consequence shows up in staffing models, audit readiness, and the data plumbing needed to produce defensible cost reports and faster revenue cycle decisions.

  • 01HFMA’s board slate now visibly includes roles that control the work: a system CFO (Corewell Health) and a chief revenue officer overseeing $7 billion in patient revenue at Orlando Health, per GlobeNewswire. That’s a signal that cost reporting and revenue cycle execution are board-level concerns, not back-office chores.
  • 02Medicare cost reporting is moving toward more granular worksheets and documentation, and each new CMS reporting requirement becomes a data-integration project before it becomes a policy memo, per HFMA’s reporting on Worksheet S-12 and its FY 2027 IPPS/LTCH PPS coverage.
  • 03HFMA’s CHCRS, CRCR, and CSPR credentials provide a concrete way to benchmark internal capability: if cost report preparation, managed care contract terms, and prior auth workflows live in different teams, credentialing can reveal where handoffs are breaking down.

FDA QMSR ties supplier contracts to inspection prep

FDA QMSR ties supplier contracts to inspection prep

FDA’s Quality Management System Regulation (QMSR) took effect Feb. 2, 2026, incorporating ISO 13485:2016 into 21 CFR Part 820 and shifting inspections to a process-based model under Compliance Program 7382.850, according to MD+DI. That change is starting to show up outside the quality department: medical device OEMs are being pushed to spell out documentation, audit support, and change-control responsibilities in contract manufacturing agreements, as Medical Design and Outsourcing described. Two recent partnership moves, Ratio Therapeutics expanding radiopharmaceutical manufacturing with PharmaLogic in Idaho Falls and Menicon shifting U.S. Rose K manufacturing access to three partners after concluding a prior arrangement, illustrate how multi-party supply chains now need contract terms that map directly to integrated QMS evidence. The operational consequence is simple: under CP 7382.850, a complaint, supplier nonconformance, or process change can pull investigators across CAPA, risk management, purchasing, and design records in one thread, so contracts and quality records have to be built to travel together.

  • 01Under FDA CP 7382.850, inspection risk increasingly sits in the “handoffs” between complaint handling, CAPA, supplier controls, and the Risk Management File, so quality evidence has to be assembled end-to-end, not by department.
  • 02For OEMs outsourcing manufacturing, the most useful contract test in 2026 is whether each clause produces inspectable artifacts, who owns them, where they live, and how fast they can be produced during an audit.
  • 03Multi-partner manufacturing models, like Menicon’s three-partner Rose K availability and Ratio’s capacity expansion with PharmaLogic, raise the bar on configuration control, supplier risk classification, and change notification across sites.

Interchangeable biosimilars cut drug spend only when pharmacies can actually switch them

Interchangeable biosimilars cut drug spend only when pharmacies can actually switch them

The FDA’s interchangeable biosimilar pathway is moving from a one-off insulin milestone to a repeatable playbook for pharmacy-level substitution, with Wezlana (ustekinumab-auub) approved as interchangeable to Stelara in late 2023 and a first interchangeable biosimilar to golimumab reported in September 2026. Evidence from a JAMA Health Forum economic evaluation cited by Podiatry Today found that insulin glargine interchangeability in November 2021 was followed by an immediate jump of more than 47,000 prescriptions for Semglee and insulin glargine-yfgn, suggesting the designation itself can change dispensing behavior. For hospitals, health systems, and payers, the operational consequence shows up less in the FDA letter and more in formulary design, NDC-level claims logic, pharmacy notification requirements that vary by state, and the inventory and education workflows that make substitution predictable instead of chaotic.

  • 01Interchangeability is a workflow change, not a clinical debate. The systems that decide spend are NDC mapping, e-prescribe defaults, and pharmacy switch rules governed by state law.
  • 02The pipeline is widening beyond diabetes. Wezlana’s interchangeability to Stelara (Healthcare Purchasing News) and a newly reported interchangeable golimumab biosimilar (Journal of Healthcare Management/AJN via Ovid) signal more specialty and infusion-adjacent categories will face pharmacy-level substitution decisions.
