What is TestSharing?
TestSharing is a digital platform for consumer requested food testing. We submit food items selected by our users to professional laboratories and deliver results on contaminants found in food. Testsharing is your new favorite mobile app to find out what is really in your food!
Is TestSharing free?
Yes! Both downloading and user registration are free of charge!
How can TestSharing help me make healthier food choices?
Making healthier food choices has various aspects and choosing a well-balanced diet remains up to you! TestSharing is simply a tool to help you choose foods that are clean, and educate you on common chemicals like pesticides and heavy metals. Check your food beyond the label and rely on our results instead of brand promises!
Who performs the tests for TestSharing?
TestSharing only works with certified, professional laboratories. All reports you receive from TestSharing contain lab results transcribed into our compehsive Evaluation Report, as well as health impact information. For more information on our laboratories, visit the Our Partner Labs page.
Aren't all contaminantes in food products controlled already?
Governmental control agencies perform occasional product safety tests to ensure public safety, but unfortunately food safety violations and scandals still occur. Producers and distributors also have their own quality control strategies, and can actually make their own decision on whether or not a chemical is harmful. Unfortunately, current regulations on food are not up to date and many toxins are not regulated at all. Consumers are left to navigate through all these problems within the food system themselves. That's where we come in.
How does Testsharing know what to test for?
TestSharing was developed with experienced food scientists, chemists and toxicologist to give our users access to the most relevent results based on market research. Our users can submit their very own product to be tested for, or vote on a pending test to get tested first!
How long is a test result valid and how representative is it?
The test result is valid as long as the producer of the tested product keeps the same standards and processes. This can vary, so we cannot give a general validity date. Our reports are kept in the database for 2 years, then are automatically removed. A test result always refers to a particular sample and doesn't represent the whole batch.
How quickly can I see test results?
You will have instant access to our vast database of completed tests or can submit a product to start a new test. Newly submitted tests are sent to our partner labs, where they conduct the test - and sent us the results. Results usually are available within 3 weeks!
How can I get started?
To start using TestSharing, all you need is a smart phone. The TestSharing app is available on Android and iOS platforms and is free to download. Download the app, register an account, and you're in!
FAQs About Our Evaluation Reports
What does AOAC 2007.01 mean?
AOAC 2007.01 is a widely accepted standardized testing technique used to test for a wide range of pesticides in fruits, vegetables, leafy salad crops and other foods. There is an extraction method followed by a cleanup method to remove sugars, lipids and other organic natural components from the sample. The samples are extracted and partitioned using an organic solvent and salt solution., Next, “GC” (gas chromatography), and “LC” (liquid chromatography) are used to separate the various chemicals.
What does GC/LC mean?
Both GC and LC are highly sophisticated and expensive analytical tools used in analytical chemistry. Finally “MS” (which stands for mass spectrometry) is the technique used to separate the chemicals further mass (weight). A detector is used and the chemicals are identified.
What does ICP-MS mean?
Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part in 1015 (part per quadrillion, ppq) on non-interfered low-background isotopes. This is achieved by ionizing the sample with inductively coupled plasma and then using a mass spectrometer to separate and quantify those ions.
What does the MRL Mean?
MRL means” Maximum Residual Limit”, and is the maximum amount of chemical residue allowed to be in a food.
This level is decided by food safety authorities in each country.
These levels are based on Good Agricultural Practice. If food producers adherestick to pesticide use guidelines and then assess for safety based on the maximum daily intake of the food and toxicity data(reference), the amounts of these chemicals found in food should not be more than the MR. Anything below the MRL should be a very small amount of pesticide and therefore should not be a concern to human health, according to the authorities.
How are MRLs set?
Pesticide companies, or registrants, must submit a wide variety of scientific studies for review before EPA will set a tolerance(reference).
What does the Concern Index mean?
Looking at the numbers on a test report can be confusing, so at TestSharing we have made things simpler for you. The scientists at TestSharing have created an algorithm to take those confusing results, and give you an easy to understand 1-100 scale. At a glance you can understand how contaminated the food is; 1 would inidicate little to no contamination and 100 would indicate higher toxicity and a potential danger to your health. Therefore the higher the number, the more contaminated it is, and more concerning to human health.
What are the “allowed levels” for heavy metals based on in your reports?
The allowed levels are based on either EU law or where there is no law for the food in question, we look at recommendations made by the EFSA. In the cases of recommendations the figure is an “ADI” (see “What does ADI mean?”) which is a daily dose amount, and also depends on body weight. That means larger people can handle more of the contaminant, and smaller people less. It also depends on the amount eaten. If more of a food is eaten (staple foods like rice and potatoes for example) then less contaminants per kg of that food would be acceptable. If less of a food is eaten (sweeteners or seasoning for example) then it may be acceptable to have higher amounts of a contaminant in it. So in a more perfect calculation, “allowed levels” would take into account any individual’s body weight and the exact amount that they ate, which can certainly be calculated, but would not give an overall contaminant level rating for the food. That is what consumers need as guidance on whether a food is safe or not.
What does ADI mean?
The ADI stands for the Acceptable Daily Intake (ADI). For pesticide residues and food contaminants, ADI may also be called Tolerable Daily Intake (TDI).(reference)
The unit of ADI for a chemical substance is mg/kg bw/d or mg/kg bw. It means xxx mg per kg body weight per day or mg per kg body weight.(reference)
The ADI is normally derived from the lowest no observed adverse effect level (NOAEL) determined from long-term animal (in vivo) studies. The ADI is calculated by applying a safety or uncertainty factor, which is commonly 100, to the NOAEL obtained from the most sensitive test species.(reference)
ADI = Long-term NOAEL (lowest value)/100 (reference)
Why are there ANY chemical contaminants in my food?
Pesticides are a part of the way that we produce food in the modern world because they are beneficial to food production. Their use is allowed but government authorities set maximum allowable limits that can be present in our food. I.e., there is a certain amount of each chemical that the authorities will allow to be present in our foods, and under those amounts it is considered safe.
What’s a carcinogen?
A chemical or agent that causes cancer.
