Cronobacter testing

Managing Cronobacter risk is essential for food safety. This microorganism, particularly critical in infant formula, requires precise and rapid testing. Eurofins Food & Feed Testing provides reliable solutions to detect and quantify Cronobacter, ensuring regulatory compliance and protecting the most vulnerable populations.

Key services

  • PCR detection (Polymerase Chain Reaction): Ideal for detecting low levels of pathogens, optimised for infant formula and its ingredients
  • Chromogenic analysis: Suitable for environmental samples, which can be tested in parallel for Salmonella spp.; shorter turnaround time than the ISO method
  • ISO 22964: Internationally recognised method, ideal for products intended for export
  • Whole Genome Sequencing (NGS-WGS): Enables comparison of strains found in the production environment and finished products, facilitating identification of contamination sources

Additional services

  • Support in developing control plans
  • Assistance in interpreting regulatory texts

What is Cronobacter?

Cronobacter is a Gram-negative, non-spore-forming bacterium belonging to the Enterobacteriaceae family. Several species make up this genus, and all can cause severe infections, particularly in infants. The bacterium is known for its ability to resist desiccation and form biofilms, allowing it to persist in dry environments such as powdered infant formula manufacturing facilities.

Sources and routes of contamination

Cronobacter spp. can survive on abiotic surfaces like stainless steel, as well as in environmental sources such as dust, soil, water, and certain raw materials. Contamination can occur through improperly sterilised equipment, water, airborne dust, or ingredients added after pasteurisation. Although infections are rare, they can be fatal in infants.
