NEWS 10 FEED & ADDITIVE MAGAZINE September 2025 Kemin Industries, a global ingredient manufacturer, announced the acquisition of Hennessy Research Associates, LLC. Based in Lenexa, Kansas—known in the U.S. as the "animal health corridor"—Hennessy Research Associates specializes in the research and development of vaccines for infectious diseases of animals. As a part of its specialization, Hennessy Research Associates' team of scientists is skilled in biological manufacturing processes, in vitro test development, lab animal and host animal challenge model development, and USDA ELISA Reference Requalification methods. The team works closely with client company scientists, technicians, and regulatory personnel to bring an optimized production process to the client's manufacturing site. "As Kemin continues to expand our offerings in animal vaccines, the acquisition of Hennessy Research Associates allows us to strengthen our position in the U.S. and global animal health markets with additional expertise and science-backed research that is critical to ensure the health and welfare of animals worldwide," said Dr. Chris Nelson, President and CEO, Kemin Industries. "We look forward to continuing to work with Dr. Hennessy and her team of experts in serving our current and future customers." Hennessy Research Associates was founded in 2001 by Dr. Kristina J.

This reinforces a growing body of scientific evidence that supports the coexistence of wild and farm-raised salmon. Recently published in Aquaculture Research, a study titled “Tenacibaculosis Caused by Tenacibaculum maritimum is Not Transmitted from Atlantic Salmon (Salmo salar L.) to Canadian Chinook Salmon (Oncorhynchus tshawytscha W.) in a Cohabitation Model” examined whether Tenacibaculosis, commonly referred to as mouthrot, in farm-raised Atlantic salmon can be transmitted to Chinook salmon through cohabitation. The study concluded that Chinook salmon cohabitating with infected farmraised Atlantic salmon showed no illness or mortality, even when exposed to high pathogen concentrations. The association highlights that this marks the first interspecific transmission study of its kind in Canada, directly addressing public concerns about disease transfer between farm-raised and wild salmon. An additional paper, recently published in Scientific Data by Nature titled “Sea lice infestation dataset for wild and farmed salmon populations on the Pacific coast of Canada (2001-2023)”, provides the most comprehensive sea lice dataset compiled for British Columbia’s coast, covering over two decades of monitoring across nearly 100 farm sites and more than 365,000 wild fish.
