List of Chemical Residues by Class/Method 

The Chemistry Laboratory Guidebook (CLG) contains test methods used by FSIS laboratories to support 

the Agency's inspection program, ensuring the safety of meat, poultry, and processed egg products. The 

CLG contains methods for the analysis of food composition, food additives, nutrients, veterinary drug 

and pesticide residues. Methods are designed to provide analysts with written documentation to 

facilitate training, performance, quality assessment, and interpretation of data. The CLG can be found at
