Food you can trust

From farm to fork, food safety is today the #1 concern within the food sector. With the emergence of new sources and forms of contamination, the immunization of certain bacterial sources and the desire to move away from the use of antibiotics, pesticides and chemical preservatives, the challenges are immense. Preventing risks associated with the transmission of bacteria, viruses and other pathogens to operators and to consumers is the primary concern throughout the food chain.  Everyone involved – farmers, veterinarians, suppliers to the farm industry, food processing plant operators, retailers…- has a stake and a responsibility in the safe production and processing of food. Failure at any stage means putting the life of consumers and staff at risk. Failure can have disastrous short and long-term consequences for a business. Failure can engage the personal legal responsibility of managers and staff.

Inventing solutions for tomorrow

Everyone involved in the food chain needs a business partner with the scientific expertise and field experience to deliver customized answers having identified the risks and critical control points. Food safety is our core field of expertise, recognized all over the world. Our products and services prevent disease and contamination in both animals and humans. Our global solutions approach delivers food and farm biosecurity. They are constantly reinvented and optimized from the sharing of results obtained on the ground and the findings of our R&D efforts, to guarantee full compliance with new regulations. We offer unique skills based on deep-rooted science developed globally and twinned with an empirical approach at local level to tailor our proposals to individual needs. We improve farm performance and add value to the food industry.
