How a chlorine-free wash programme could benefit your milking equipment cleaning regime


Dairy farmers are now turning to the use of a chlorine-free wash programme in their daily cleaning routines to disinfect and clean their milking equipment.

Chlorine-free products help to greatly reduce the levels of trichloromethane (TCM) and chlorite residues in milk.

The Kersia chlorine-free wash programme

Kersia takes great pride in manufacturing effective chlorine-free based chemical products, specifically designed to provide a robust cleaning programme for milking-machines and bulk-tanks.

Its five-stage cleaning cycle programme has been created to provide a simple and comprehensive clean before and after use of the farms milking equipment, as well as an extensive rinse at each stage of the milk production process.

At least three times per week incorporate a hot acid product such as Autoscan Red to remove mineral deposits using water at 70º minimum temperature. This is also suitable for use in milk bulk-tanks to complete the chlorine-free programme.

‘An added positive’

Irish dairy farmer Pat Kiely from Co. Waterford has been farming since 1976. Today he runs a 300ac dairy farm alongside his nephew Ciaran Hanrahan, who is responsible for the daily care of over 270 dairy cows.

Pat has been using Kersia’s Autosan Blue, Autoscan Red and Novo Spray teat dip for over three years. Amongst some of the most dramatic results after switching to Kersia’s chlorine-free wash programme was the significantly reduced total bacterial count (TBC) and thermoduric counts.

The reduction in instances of mastitis in the herd from moving onto the teat dip was an added positive. The reduction in mastitis cases has vastly reduced expensive vet bills and widespread antibiotic use as a part of a programme of selective dry cow therapy (SDCT).

Pat said: “We have been using Kersia products for over three years now and we have recorded consistently low TBC counts of between 3,000 and 6,000 and thermoduric counts of 100 or less.

“Our excellent hot water supply provides us with water at 90º and a solution circulation temperature of 70º. This, coupled with the use of our excellent Kersia chlorine-free wash programme products, has undoubtedly helped us to achieve and maintain these results.”

Mike Kissane, from Listowel Co, Kerry, has been using Kersia’s Autosan Blue and Autoscan Red on his dairy farm in Listowel, as part of his chlorine-free cleaning programme since June 2019.

Mike Kissane has been farming outside Listowel, Co. Kerry, since 1997 on approximately 150ac. He is milking cows through a 20-unit Dairymaster herringbone milking parlour.

Since June 2019, Mike has been using Autosan Blue and Autoscan Red on both his bulk-tank and milking machine. When initially looking for a chlorine-free product, he wanted liquid products to suit his automatic washer that were easy to use and were effective in both hot and cold water.

The products also needed to be easily integrated with his automatic tank and milking machine washer. Above all else considering the many costs associated with dairy farming, Mike wanted products that were competitively priced and put simply – they needed to work as effectively as the products before them which contained chlorine.

With all these prerequisites in mind, Mike sourced both Autosan Blue and Autoscan Red from his local Kerry Agri branch in Listowel. For the back-flush system on his milking machine Mike also uses peracetic acid (Virodox).

When asked if the Kersia/Kilco products met his expectations, Mike said they did.

We have mineral deposits in our water which can be hard to wash from the machine but thankfully, despite the absence of chlorine, we achieved the results we wanted from using the Kersia products in conjunction with the correct volume of hot water.

“So far, washing without chlorine in these products has not been an issue for us.”

Kersia can provide a complete cleaning solution for a chlorine-free wash programme for all types of milking parlours. Its range of specially developed products can reduce chlorate and TCM levels in milk whilst consistently providing low bacterial counts through effective cleaning.

A study undertaken by Teagasc Moorepark at Kilworth research farm in 2018 found that a chlorine-free routine was as effective as standard cleaning protocols already in place and at a comparable daily cost.
