Nutrient and Contamination Levels in LabDiet® Certified Laboratory Animal Feeds
Based on data compiled from 1993-2012 by Purina LabDiet® and in conjunction with an independent laboratory.

Animal diets used in laboratory studies must provide consistent and proper nutrition.1  To assist in experimental control, feed manufacturers must ensure that all batches of feed meet approved nutritional profiles.2  Certified diets for laboratory animals are commonly used in toxicological studies where control of contaminants, such as pesticides and heavy metals, is imperative.  Certified LabDiet® products manufactured by PMI are analyzed prior to sale and guaranteed not to exceed established maximum concentrations of key contaminants.  PMI controls variables that could adversely affect study animals and possibly lead to inaccurate conclusions.  Certified LabDiet® products meet the recommendations of the FDA's Good Laboratory Practices Program.

This report is an update to our 2007 published bulletin "Nutrient and Contaminant Levels in LabDiet® Certified Laboratory Animal Feeds: 15-Year Technical Bulletin" which reports the results of our ongoing efforts to provide diets that are consistent from batch to batch as well as year to year.  The data reported in this bulletin includes that from 1993 to 2007 and now 2008 to 2012.
