Your Kitchen and Mold

Kitchen Mold Removal

Are you concerned that black mold could be lurking in your kitchen, perhaps hiding in the cupboards? Not only is it unattractive, it can also cause respiratory problems for your family. The following guide can help you locate, prevent and destroy any black mold that has taken up residence in your kitchen.

Where to find black mold in the kitchen?

Black mold tends to grow in dark, damp areas, which means it could be festering in a kitchen cabinet or cupboard for a long time before you uncover it. For this reason, it’s vital that you identify the areas in your kitchen that are going to be most prone to mold growth. This will give you the necessary knowledge so that you can find the problem before it gets too bad. Places to check include the following:

    • Underneath the kitchen sink. Check the cabinet bottom and the back wall where the sink pipes enter for dampness or past signs of water damage, such as bubbling or peeling surfaces. Even if black mold isn’t visible, it could be growing on the underside of the sink cabinet or behind the wallboard.
  • Under the refrigerator. A leak from a water line to the icemaker or simple condensation collection underneath the fridge could create the optimum environment for fungal growth. If your kitchen flooring looks like it has suffered water damage or if there is standing water and mildew present, black mold could also be growing under the floorboards. Also, check any cupboards near the fridge to make sure there is no moisture damage.
  • Cabinets above or next to wall mounted microwaves or oven hoods. Another common trouble spot is behind the cabinets that border microwaves and hoods. This is because moisture and condensation from cooking can accumulate in these cupboard areas, especially if ventilation is insufficient.

Kitchen mold prevention

Since prevention is key to black mold management in the home, now that you know your kitchen’s trouble spots you are better able to stop it from growing in the first place.

Begin by checking underneath the sink on a regular basis and fixing leaks immediately. Keep the sink cupboard area clean and neat so you can empty it out for a quick leak check regularly. If you are like many people and use this cupboard area for cleaning supplies, place the supplies in a handled carrier so you can quickly pull everything out. A good time to check is after you have been using the sink, such as after dishwashing. If there is a leak, it is likely going to be damp if you just drained the sink.

As for the fridge, it’s good practice to pull it out and dust the rear coils every one to two months, anyway. Simply pencil this chore into your home maintenance calendar. You can then use this opportunity to check beneath the fridge for leaks and to make sure water lines are attached and not leaking.

Finally, inspect the area around and under the cabinets, microwave, and hood after you use the oven or microwave. If you find a lot of moisture or condensation, chances are that you need to add a stronger fan or better ventilation to the kitchen.

Kitchen mold removal

Black mold can be tenacious when it comes to removal. Although you can often remove the visible black mold by yourself, there is likely hidden mold that you cannot find for removal as easily. The basic removal process is as follows:

Step 1: Testing Testing is done if there is signs of moisture but no obvious visual signs of fungal growth. Testing may also be done if there is light visible growth, since the remediation firm will need to determine the extent of the growth.
Step 2: Seal the infested area The home is sealed. This means that the area that has mold, in this case the kitchen, is sealed off from the rest of the house so that black mold removal doesn’t send spores into other areas.
Step 3: Identification and replacement The cause of moisture is identified and fixed. Otherwise, the mold will simply return if there is still a moisture source. This may mean the removal and replacement of cabinets and wallboard so they cleaning can occur under them.
Last step: Removal and cleaning The actual removal and remediation begins. The crew will use a disinfecting and cleaning solution that removes and kills the fungus. Stains from the black mold may be present on cabinets, but these can usually be painted over and repaired.

Summer vacations are when mold comes out to play

 

 

Summertime traditionally brings family trips, school vacations, as well as plenty of hot uncomfortable weather. Those sunny days, however, often come with high humidity and afternoon thundershowers — ideal conditions for annoying and potentially toxic mold.

It’s a pervasive menace that is poised each summer to grow and thrive in your house. Left unattended, fast-growing mold can cause damage that will cost in the thousands of dollars to eradicate or, worse, pose a dangerous threat to the health of your entire family.

“No one knows how many homes have mold behind the walls, but the best estimate is about 70 percent,” said Richard E. Gots, a doctor and founder of the International Center for Toxicology and Medicine, a biomedical consulting firm.

Gots’s estimate refers to mold that is at an “elevated level” and therefore should be addressed if the conditions exist for the mold to take hold and grow.

The Environmental Protection Agency sets levels for acceptable radon levels as well as a threshold for lead in the house or water supply, and states regulate termite inspections and control compliance. Yet there are no federal or state regulations that dictate a safe level of mold for a residential property.

D.C. Council member Mary M. Cheh (D-Ward 3) has been campaigning for several years to pass legislation that would require residential property owners, including landlords, to disclose the presence of mold in their apartment, condo or house. This legislation is still pending.

 According to the District’s housing code, the Department of Consumer Regulatory Affairs (DCRA) inspectors cannot cite a homeowner for mold because the city considers mold to be “an environmental problem,” rather than a housing or safety issue. Mold, of course, is notoriously difficult to detect, and what may look like dangerous mold can only be legitimately determined under a microscope by a competent inspector or lab. Additionally, most homeowner insurance policies will not cover damage from mold — they consider it a “preventable” condition.

In reality, mold is a fungus that can grow anywhere moisture is present. Mold spores thrive in warm temperatures (77 to 86 degree Fahrenheit) and wherever there are damp conditions. Mold spores are in the air we breathe, and they can grow on any surface. In a house, mold can be found in ceilings and walls, under sinks, in drywall, hidden behind wallpaper or baseboards, in the ductwork or even on furniture and clothes. It can also grow outdoors under wood piles or mulch, gutters or abandoned trash.

Mold in a house can lay dormant until it gets the needed heat and humidity to grow and multiply. Additionally, it needs a food source, such as dust, dirt or some other organic debris.

While not everyone will react to this growth in the same way, those sensitive to allergic or toxic mold can develop alarming symptoms upon merely entering a contaminated room. The result can be a serious — even life-threatening — illness if not treated in time.

 If you suspect that you’ve been exposed to mold — or begin to experience dizziness, fatigue, nausea, shortness of breath or other symptoms of illness — contact a mold specialist and have your property inspected as soon as possible. Licensed professionals will test the air quality of your house and take samples of the visual mold, which will be sent to a qualified lab for evaluation.

The EPA provides helpful information in its publication “A Brief Guide to Mold, Moisture, and Your Home” at www.epa.gov/mold/moldguide.html . And the Centers for Disease Control and Prevention focuses on the health hazards of mold exposure and provides recommendations for removing mold exposure at www.cdc.gov/mold/dampness_facts.htm#note .

In addition to the traditional methods for eradicating mold (such as using chemicals or chlorine bleach and physically removing infected surfaces), there is a new, enzyme-based alternative. Previously used as a protective spray for fruits and vegetables, it is now available for home use.

Jenn Sherwood, manager of Green Home Solutions of Maryland, says that the enzyme spray is a cost-effective, time-saving and environmentally responsible way for homeowners to eradicate mold. The process uses a “fogger,” which emits a fine spray that is able to penetrate most porous surfaces (such as drywall) or even non-visible areas — behind walls or inside insulation. This method of eradicating mold often eliminates the need to remove and replace the existing material.

The EPA regards this spray as nontoxic to humans or pets and harmless to both surfaces and belongings in the home. The enzyme works by creating a bond with the mold spore, and then breaking it down from the inside. As a result, the mold is chemically altered into a particle that is no longer allergenic, toxigenic, or able to reproduce other spores. This treatment can cost from one-third to one-tenth less than the cost of traditional methods.

Given that your insurance company may not cover mold damage, it’s important to take immediate action.

Here are three easy steps to help prevent mold when you go on vacation:

●Check for areas where water could accumulate — such as around windows, doors, bathroom leaks, kitchen sinks and washing machines.

●Clean surfaces of oil, soap, dust and dirt. Those materials are a feeding ground for mold when moisture is present.

●Set the temperature inside the house in the low 70s, if possible. If you suspect humidity, set a dehumidifier to keep the moisture level below 60 percent. In your closet, place a hanging moisture absorber (such as Damp Rid) that will trap excess humidity and eliminate musty odors.

Debunking some toxic mold myths

In 2000, a new “toxic mold” panic swept the country, and after 16 years of untold lawsuits and billions of dollars spent, major myths still plague and unnecessarily panic association boards, managers and homeowners. The myths all too often cause exaggerated repairs, unduly frightened residents, and conflict. In this and the next column, I will address thirteen pervasive toxic mold myths.

1. Mold is new. Mold, one of the earliest and simplest life forms, has existed for thousands of years. Almost 100 years ago, mold was the basis of the discovery of penicillin. Mold is ever-present, as is dust or pollen.

2. The scientific and medical communities confirm mold’s many dangers. In 2004, the National Institute of Medicine published its comprehensive study on indoor mold exposure, called “Damp Indoor Spaces and Health.” A central finding was: “Scientific evidence links mold … in homes and buildings to asthma symptoms in some people with the chronic disorder, as well as to coughing, wheezing, and upper respiratory tract symptoms in otherwise healthy people… However, the available evidence does not support an association between … mold and the wide range of other health complaints that have been ascribed.”

 That sounds like mold is as dangerous as dust or pollen to people with severe asthma. The announcement containing this finding is easily located by a web search, but it did not receive much press play – stories of frightened people living in tents are more interesting.

3. One must determine the kind of mold present. Mold consultants and plaintiff attorneys often describe some molds as worse than others. The most famous mold is stachybotrys chartarum, a mold producing infinitesimal quantities of a substance similar to botulism poison. However, the amount is so small they call it a “mycotoxin.” It sounds frightening, but the scientific community long ago debunked the myth that this or any mold was somehow poisonous to breathe. For example, read the National Institute of Health Fact Sheet on Mold, found at www.niehs.nih.gov.

4. California is protected by the Toxic Mold Protection Act of 2001. The act instructed the Department of Public Health to develop permissible exposure limits of the various mold strains. However, in 2005, and again in 2008, the DPH reported the task could not be completed with the scientific information available. Consequently, there is presently no official standard as to how many mold spores of any given variety are “unhealthy.”

5. Always start with a mold test. The Environmental Protection Agency recommends against mold testing. There is no standard as to how many mold spores are “unhealthy,” and indoor air sampling tests are extremely vulnerable to events in the home, which can change the results. A recent shower, window opening or carpet cleaning are some of the many factors that can completely change test outcomes.

Mold tests, to put it bluntly, primarily frighten the occupants and create a “need” for the expense of a mold consultant, and a second test after the area is cleaned. Since the health authorities have not confirmed any particular strain is more dangerous, and since there is no official standard as to how many airborne spores are unhealthy, there is rarely a good reason to spend the money on such a test.

 

A DNA-Based Innovation to Identify Molds and Bacteria in Homes

Numerous health problems in the United States are associated with mold (i.e., fungi) in homes, schools, and businesses.  With a technology developed by EPA researchers, these problems can be identified quickly and accurately, allowing illnesses to be diagnosed and treated more effectively.  Perhaps more important, use of this technology may prevent disease occurrence.

EPA’s DNA-based process can identify and quantify more than 130 species of toxic molds and potentially pathogenic fungi in the environment.  Fungi and bacteria cause or contribute to many health problems, including infections, gastroenteritis, ulcers, asthma, allergies, and sinusitis.  This invention may have applications in research related to therapeutics and diagnostics for these illness.  Additionally, this technology can be used to:

  • Determine whether an environment is abnormally mold contaminated.
  • Test homes for potentially pathogenic molds
  • Test water for pathogenic molds.
  • Monitor hospitals to prevent nosocomial mold infections.
  • Rapidly diagnose mold infections so that treatment can begin earlier.
  • Monitor fold and drugs for mold contamination.
  • Measure the risk for mold associated with allergic and asthmatic disease.
  • Diagnose chronic rhinosinusitis.
  • Monitor crops for mold pathogens in an integrated pest management program, thus reducing the use of pesticides.

This method provides real-time results that are more accurate and less time-consuming than previous technologies.  EPA-licensed commercial laboratories in the US have used this method to provide testing services for their clients.

This technology was licensed by 15 companies, 11 of which are small US businesses.  The first license was issued in 2000, and word spread quickly about the technology, leading to many more non-exclusive licenses within a few short years.  The patent didn’t issue until 2002, after there were already several licenses in place.

Mold Complaints at Grant Sawyer State Building Prompt Repairs

Grant Sawyer State Office Building (Screengrab/Google Streetview)

Crews are replacing heating and ventilation equipment in the Grant Sawyer state offices in Las Vegas after a report cited a possible link between leaks in the system and the presence of low concentrations of two species of mold in the building’s dust.

The report came after at least 10 state employees working at the Las Vegas building filed worker’s compensation complaints in November alleging that mold caused “building-related symptoms,” including respiratory illness and headaches, that typically go away when people leave the contaminated environment.

The investigation, led by Reno-based environmental medicine specialist Dr. James Craner, found that leaky valves in the heating and air conditioning system may have allowed water to drip into the ceiling tiles, creating a friendly environment for mold spores to grow.

Though the moldy dust on its own doesn’t prove that the leaks created a contamination, fixing the HVAC system and cleaning the “presumably mold-contaminated carpet” of dust could clear the low levels of mold, the report said.

“These HVAC leaks and occupant health complaints are postulated to be the same as those that occurred in the mid-1990s,” Craner wrote on April 4, referring to a prior “sick building syndrome” case that plagued the state office building. The mold likely settled in the carpet and could be inhaled by employees while they walk or conduct office maintenance, the report read.

Tests on the air’s mold concentrations came back nonharmful, and samples of settled dust showed very low concentrations. The two mold species detected at higher concentrations throughout the building included the Stachybotrys chartarum, which is “highly associated with building-related symptoms,” the report said.

Nevada Department of Administration Director Patrick Cates wrote in an update Friday that the state was following Craner’s recommendations to replace the HVAC valves throughout the building by May 5.

The department also plans by July to deep-clean the building’s carpets and other surfaces that may have been contaminated by mold.

Four months after the deep cleaning, the department will retest for mold, Cates said.

“If the tests continue to show atypical molds, we will continue with further investigations and remediation measures until these concerns are resolved,” Cates wrote.

Severe reactions include fever and shortness of breath.
