Project Title: Evaluation of chlorate development in milk and dairy products with specific focus on milking equipment cleaning protocols and maintenance of milk of high microbiological quality.


Lorna is from a dairy farm in West Cork and has an array of practical dairy farming experience in Ireland and has worked in New Zealand as part of her undergraduate degree. Lorna is looking at chlorate residue development in milk and how it can be minimized. Her research will place specific focus on milking equipment cleaning protocols with particular emphasis on chlorine free cleaning and how this effects the bacterial quality of milk. Most notably, this area of research is of special interest to the dairy industry because of the compulsory removal of chlorine as a cleaning agent for milking equipment and CIP systems within processing plants from January 2021. This policy move is a consequence of the demands of the markets in which Irish products are traded in. Product quality and food safety are of paramount importance to the international consumer; particularly in specialist markets such as infant milk formula. To sustain our current position in important markets and ideally grow them and enter new ones the industry needs to provide the safest and highest quality products possible. It is vital that changes such as chlorine removal do not sacrifice other integral components of the system. Lorna’s research is mindful of this with its focus on maintaining low bacterial levels in milk while minimizing residue levels in bulk tank milk.
