Food Analysis

2. Pesticide Standards

Positive List-Related Reference Standards

A positive list system related to residual pesticides, feed additives, veterinary drugs in foods, etc. has been introduced pursuant to the Law to Partially Revise the Food Sanitation Law (Law No. 55, 2003).
Wako has continued to launch reference standards for residual pesticide analysis and HPLC analysis of veterinary drugs. Other items are expected to be added in the future.
