Unlike other methods and equipment on the market, it's an easy to use food safety testing device with a simple interface and clear, unmistakable results. Pesticide residues above the maximum residue limits (MRL) were detected … Obtain and unpack an insecticide test kit. The two levels are combined with an added “safety factor” (which lowers the allowance by one or two orders of magnitude to err on the side of caution) to arrive at an estimate of the total allowable exposure from all sources that would protect public health. High Accuracy:The results displayed are certified to be more than 90% accurate according to third party testing more than enough to determine the safety of the specimen. Many farmers apply too much fertilizer. Because the agency targets specific commodities that have shown past violation and does not randomly sample from the entire spectrum of agricultural products, the GAO said, “FDA cannot reliably evaluate the extent to which its monitoring program detects and intercepts violations at a rate greater than random chance.” In addition, the report stated that the FDA does not test for violations of the established tolerances for several common pesticides. An insecticide test kit allows you to detect the presence of insecticides in fruits and vegetables to get an idea of what you are consuming.
