Gibraltar Laboratories has published its 90th paper. The current issue of Contract Pharma has our article entitled “Microbiological Testing and Contamination Control – an opinion on the microbial limit test with reference to harmonization”. We are proud of the contributions of our technical services team to this effort: Christopher Waskewich, Kristah Kohan and Danina Rinaldi. Our paper provides an opinion on the harmonization of USP microbial limits testing. It provocatively analyzes the changes that were made to USP Chapter <62> in order to win consent from the Europeans. You will find a copy at https://www.gibraltarlabsinc.com/publications.html.
