ISO 22964 Cronobacter spp. Detection in Fermented Dairy Products
The presence of Cronobacter species, particularly in fermented dairy products, can pose significant health risks to infants and young children. ISO 22964 provides a standardized approach for the detection of these bacteria. This service ensures that fermented dairy products meet stringent quality control standards by identifying potential contaminants early on.
The methodology outlined in ISO 22964 is rigorous, focusing on the isolation and identification of Cronobacter spp. from fermented dairy samples. The protocol involves several critical steps including sample collection, homogenization, enrichment culture, selective plating, and confirmation using biochemical tests.
The importance of this testing cannot be overstated in the context of infant formula and other pediatric products. Failure to detect Cronobacter early can lead to product recalls, costly legal disputes, and reputational damage for manufacturers. By adhering to ISO 22964 standards, companies can ensure compliance with regulatory requirements and safeguard public health.
The testing process begins with the collection of samples from production lines or storage facilities. These samples are then homogenized using sterile techniques to ensure a representative mixture of all potential contaminants present. Enrichment cultures are used to enhance bacterial growth prior to selective plating, which allows for the isolation and identification of Cronobacter spp.
The biochemical tests employed in this process include reactions that differentiate Cronobacter from other closely related genera like Enterobacteriaceae. This ensures accurate detection without false positives. Once identified, cultures are further analyzed using molecular techniques such as PCR to confirm the identity of the bacteria.
The significance of this service extends beyond compliance with ISO 22964; it also aids in process optimization and quality assurance by identifying potential sources of contamination early in the production cycle. This proactive approach can help prevent costly product recalls and improve overall product safety.

In summary, ISO 22964 compliance through our testing service ensures that fermented dairy products are safe for consumption by infants and young children. By adhering to this standard, companies can protect public health while maintaining a strong reputation among consumers.
Applied Standards
The primary applied standard for this service is ISO 22964:2011, Microbiology of the food chain - Horizontal method for the detection and identification of Cronobacter spp. in foods. This international standard provides a comprehensive framework for detecting Cronobacter spp. in various food matrices, including fermented dairy products.
The standard emphasizes the use of validated methods to ensure accurate and reliable results. It covers sample collection, preparation, culture conditions, isolation techniques, and identification criteria based on phenotypic characteristics and molecular markers.
In addition to ISO 22964, we also adhere to other relevant standards such as ASTM STP 1837, which provides guidance on the preparation of samples for microbiological analysis. These guidelines are essential for ensuring that our testing procedures are consistent with industry best practices.
Our laboratory is accredited according to ISO/IEC 17025, which ensures that we maintain high standards of technical competence and quality assurance throughout all stages of our testing process. This accreditation is a testament to our commitment to providing accurate, reliable data that meet regulatory requirements and industry expectations.
Scope and Methodology
| Step | Description |
|---|---|
| Sample Collection | Collection of samples from production lines or storage facilities, ensuring a representative mixture. |
| Homogenization | Use sterile techniques to homogenize collected samples for even distribution. |
| Enrichment Culture | Growth enhancement of Cronobacter spp. using appropriate media and incubation conditions. |
| Isolation on selective media that favors the growth of Cronobacter spp. | |
| Confirmation Tests | Biochemical tests to differentiate Cronobacter from other similar genera. Molecular techniques like PCR for final confirmation. |
The process starts with the collection of samples from production lines or storage facilities, ensuring they are representative of the entire batch. Samples undergo homogenization using sterile techniques to ensure even distribution and proper preparation for subsequent steps.
Following homogenization, enrichment cultures are conducted under controlled conditions designed specifically for Cronobacter. This step enhances bacterial growth, making it easier to isolate Cronobacter spp. from complex matrices like fermented dairy products.
Selective plating follows the enrichment step, where samples are plated on media that selectively favors the growth of Cronobacter. This helps in isolating colonies that may contain the target bacteria. Identification is then performed using a combination of biochemical tests and molecular techniques such as PCR to confirm the presence of Cronobacter spp.
The use of standardized methods ensures consistency and reliability, meeting both internal quality control standards and external regulatory requirements. This approach guarantees that every test conducted adheres strictly to international best practices outlined in ISO 22964.
