The company's tests for contamination in milk, has been installed at Scottish Milk Dairies, which produces 30 million litres of milk a year, a US specialist dairy producer, Gehl's Guernsey Farms and German company Berchdesgadenerland dairy.
The group's equipment is able to process contamination tests within 48 hours which means that dairy producers can identify safety problems before their products get into the distribution chain. This, the company said may prevent dairy companies making costly product recalls.
Last week the company announced its renewed contract with Milk Link, the UK's largest UT milk producer, and it said that now it is reestablishing itself in the sector.
"The strategic implications of these placements across regions...underscore the continued success of our product group in securing the leadership position in the European dairy testing business, in addition to expanding our dairy markets around the world",the group's executive, Jay LeCoque stated in a Reuters report.
Celsis has undergone some major restructuring and has centralised its research and development unit in Germany over the last four years, and this has allowed the group renew its focus in the sector.
Dairy products safety is an important issue in the market. Consumption of products such as UHT milk is increasing steadily according to industry reports. It is estimated that UHT milk will in the long-term outsell regular milk. Thus consumer trust is becoming increasingly important.
The rapid diagnostics firm also produces tests for the Pharmaceutical, cosmetics food and beverage industries. Its technology is used to detect microbe activity in finished products providing safety to consumers.
