‘APPALLING’ quality of dairy detergent sterilisers used in Ireland has been revealed by Teagasc.
Results given after 12 products were tested showed only five had the ideal ratio between caustic and chlorine components, of about five to one. Announcing the results to members of the Guild of Agricultural Journalists of Ireland, who visited the Moorepark research centre last week, the head of the Animal Production and Grassland Research Centre, Dr Pat Dillon, said some products were also wrongly labelled, and he warned of the danger of chlorine contamination of dairy products.
Milk processors have warned that excess chlorine from detergents used when cleaning the milking system, or bulk tank, can result in a trichloromethane residue in milk.
They say chlorine is one of the most effective, efficient, and economical substances to kill or remove bacteria from milking-machine and bulk-tank surfaces, but chlorine detergents must be used correctly and carefully.
Otherwise, there can be very negative effects on dairy products manufactured from tainted milk, which can affect exports.
Farmers are advised to drain remaining milk in the milking plant before rinsing, until all remaining traces of milk have disappeared.
The main detergent solution wash is then carried out, using a reputable detergent at the correct concentration, recommended temperature, and for the recommended period of time.
A second rinsing, with water, is then needed to remove remaining traces of detergent, after which any remaining water in the plant is drained.
