What is the effect of using improper sampling techniques?

Using improper sampling techniques can lead to potential health risks because these techniques may not accurately represent the entire batch of a product. This can result in certain harmful contaminants or unsafe elements not being detected in the tested samples. For example, if a sample is taken from a non-representative section of food or a substance, it may appear safe when, in reality, the batch could be compromised elsewhere. Additionally, improper sampling can lead to erroneous conclusions about the quality or safety of products, which may ultimately expose consumers to danger. This highlights the crucial role that accurate sampling methods play in ensuring safety and maintaining public health standards.
