Testing for mold in your home is not really a complicated process, but if you should know that if you do not follow the instructions that come on the package to the letter, the test will be almost completely useless both to you and to the mold laboratory that you send the test kit samples to. Most test kits are fairly straight forward, but this is a rundown of what you are going to have to do, even if you do not use just the test kits.
Sometimes knowing where you need to test for mold contamination is pretty easily simply because of the fact that the mold is either completely visible on the walls, ceiling, or other belongings, but also due to the fact that many kinds of mold have a significant musty odor to them. You can take a sample of the mold that you can see on the walls by taking a knife (a clean one) and scraping some of it off into the test kit. Be careful here and do not inhale the mold spores. Wear rubber gloves and a respirator while doing this, if you can. Whether you are wearing gloves or not, though, you should wash your hands afterward before going to test another site and especially before you eat anything.
If you want to, you can also take a piece of scotch tape and lift some of the mold off the wall. Some people may prefer this over the knife method, but it is a matter of personal preference. The knife method is more likely to stir up the spores than the tape method.
Set a test kit out in every room of your home after you have run the air conditioner or fans in every room for about ten to fifteen minutes to get the spores stirred up. Tape at least one kit to the grill of an air conditioning vent so you will know if there is any mold growing inside the duct itself. If the air conditioner continues to blow mold spores out into the house after it has been run for about 15 minutes, you know you have a problem in your ventilation system.
After you collect the test kits from around your house, you need to label them all with your name, address, where each test kit was used in the home, and any other pertinent information. This should also include how long you left the test kit setting out in your home, whether it was 30 minutes or a day.

Mold Likes Your Food
Mold likes food just as much as we do, but we do not usually like to find it sharing the same space as the food that we stock our refrigerators with every week or two. While we all lead busy lives and are usually too occupied to remember to clean out our refrigerator, what we do not realize is that mold is also leading a busy life consuming and contaminating our food. It can contaminate almost anything that you put in your refrigerator and most of the time if it does contaminate something, you just have to throw it away. There are some things that you can do to prevent mold from growing in your refrigerator and there are a few items that you can save even if they do get a little moldy.
Keep track of what you have in your refrigerator and how long you have had that same item in there. Make a note of expiration dates. Things like sour cream, jellies, jams, marmalades, and anything else that has high moisture content can become moldy faster than you think and if they do, unfortunately, there is not much that you can do to save these items. Throwing them away and replacing them is about the only thing that you can do.
Those little plastic bags in the produce section of the grocery store sure can be convenient, but once you get your produce back home, you should remove it from these bags. Condensation gets trapped inside the bags and this will cause your fresh fruit and vegetables to rot faster than they normally would if you just put them in the crisper by themselves.
To clean out your refrigerator as regularly as you can remember to is also some good advice. Keeping bacteria and mold spores from building up in the fridge is one of the best ways to prevent mold from growing there. You can use bleach to kill the mold inside your refrigerator, since there is no surface inside that is porous. Bleach will not kill mold growing on porous surfaces. If you have to use bleach, do not mix it with any other chemicals you might have in your kitchen cabinet, especially ammonia. This is dangerous and can produce hazardous fumes.
If a dense item in your refrigerator develops spots of mold on it, such as hard salami or a block of cheese, take a clean knife and cut both around and underneath the moldy spot one inch. Do not touch the knife to other areas of the product and discard the chunk you cut out.

How to Effectively Clean Out Your Fridge
The refrigerator is an important center of the household and as such, you would think that people would remember to keep these food centers cleaned more often than they tend to. Even though it is fairly cool inside, mold can still grow very well in these cool temperatures, as anyone who has opened a jar of spoiled grape jelly can surely tell you. Whether it is a jar of grape jelly or a casserole left in the fridge for a bit too long, mold can grow on anything in your refrigerator that it can get onto. This includes, well… just about everything that is not completely sealed up, such as home-canned goods that have not had their seals broken. Mold spores are everywhere and in the air we breathe, unless the air is purified, such as in a hospital or laboratory clean room, so it is fairly hard to keep mold completely off of something we do not want it on, but it can be done. It just takes a little effort. Cleaning out your refrigerator and knowing what to do with moldy food (some of it can be saved, believe it or not) is essential to keeping a healthy kitchen.
Take everything out of your refrigerator and put it either on your kitchen table or on the counters for you to deal with later. You will go through these items after you are finished cleaning out the inside of your refrigerator.
Remove all drawers, shelves, and racks so that you can wash them in the sink in whatever household chemical you have chosen for this task. Whether it is anti-bacterial soap, bleach, or even better, a chemical made specifically to kill mold, use plenty of it, but do not mix chemicals, especially bleach. If you do use bleach, do your best not to get it on your hands. Wear rubber gloves.
Wash the inside of the refrigerator with a sponge or a rag thoroughly. To get some things that might be stuck to the wall of the fridge or stuck to a shelf off, let some warm water and some of the chemical you have chosen soak on it a few minutes. After you are done with the inside of the refrigerator, wash the parts that you removed, dry them, and replace them.
As for the food you took out, put back everything that is not contaminated with mold. Anything with a high moisture content that is contaminated like sour cream or jelly must be thrown away. Blocks of cheese or dense items like hard salami can have the molded parts cut out and thrown away. Cut 1 inch around and one inch under the molded part(s), remove, and discard. The rest is usable.

Home Canned Food and Mold
Most of us like homegrown and prepared food, but sometimes when we can them in glass containers when we have too much garden produce to eat or too much to just give away, it does not all go according to plan. There are some tried and true canning techniques that have been in use in the past century or more, but sometimes we forget to use common sense when we are canning and this can lead to mold contamination in our food that we worked so hard to prepare and preserve.
We like to can our own food because we know exactly what chemicals and pesticides are going into it. Most of us do not like the idea of chemicals being put onto our food, even if they are deemed “safe” by the government or FDA. Sometimes the chemicals that they say are safe today are not safe tomorrow. But, mold contamination can be just as dangerous as any pesticide or preservative and there are a few things that you can do as a home canner to prevent this from happening to your canned items.
Make sure that the fruits and vegetables that you are canning are of the best quality from your garden. If they have any bad spots on them, cut these off or simply do not can them. Fruits and vegetables need to be washed and some need to be peeled before you can them. Starting with good quality ingredients is key.
Do not pack the food too tightly into the jars that you will can them in. The food in the center does not get to the high temperature that it needs to in order to kill bacteria and mold spores. You should pack food loosely, with at least a few inches from the top of the jar, depending on the size that you are canning in.
After you fill the jars, put the lids and the bands on. Start processing the food immediately so that mold and bacteria do not have a chance to start growing. If mold spores get into the jar, you might have a problem, because sometimes high temperatures just do not kill mold spores. Make sure any equipment that you use is completely sterile.
If you do happen to find mold growing in a jar after you open it, just throw it away. Foods that have a high amount of moisture are not salvageable when they become contaminated.

General Rules For Mold Testing Kits
If you are unfortunate enough to have to test your home for mold, you are probably thinking that this is going to be a pretty inconvenient thing to have to do. Well, it might not be fun to think that you have disease-causing mold living in your house, but doing the actual test to determine if it exists is not really that hard to conduct at all. Whatever kind of test kit you end up using, the directions on the package must be followed to the exact letter or you will probably render the test useless. There are a few quite general rules that you should follow to get the most out of your testing kits.
If you can see the mold growing in your wall, ceilings, carpet, or on anything else in the home, you do not really have to do any guesswork as to whether you need to test the home or not. If you see anything like this, do not only test that room; test your entire home. Every room needs to be tested and this includes the ventilation system, because it extends to every room in the house and if mold is growing in the vents, it will spread to the rest of the house.
Run the air conditioner or fans in every room in your home before you put out the test kits so that if there are any mold spores in the room, they will be stirred up into the air and will settle down in the kit. Do not set them up anywhere high; a coffee table or somewhere around the mid to low level of the room should be fine. If you set them up too high, you may not get a good sample.
If there happens to be mold growing visibly on anything, you can use a piece of scotch tape to lift the mold up off the surface and place it into the test kit. There is a method that you can use involving scraping some of the mold into the kit with a knife, but since this can stir up mold spores even more, unless you are wearing a respirator, you are probably better off using the tape method.
To test the ventilation system, the best thing that you can do is tape a test against the grill of one of the ventilation ducts so that the air coming out of it is hitting the testing kit at a 90 degree angle. This will allow you to get the maximum amount of exposure.
