Swab sampling website shall not be recurring and swabbing shall not be done in the identical locale of kit where by the swab sample is already collected ahead of.
Examples of problem tests may include things like minimum detergent Speak to time, minimum amount or greatest temperatures and least rinse time/quantity/pressure. Worst situation problem tests is of particular significance when handbook cleaning systems are employed.
