Food Testing

 

As the world population continues to expand, there is increasing demand for food testing to verify the safety and authenticity of food products. Food testing ensures that food products are pathogen-free and safe for consumption. In addition, there are increasing global regulations on import and labeling of foods containing genetically modified organisms (GMO), for which testing is required to ensure compliance. Increasingly, molecular biology methods such as quantitative PCR assays and advanced DNA sequencing methods are the fastest and most reliable ways to detect pathogens and identify food components. Both analysis methods rely on the highest quality extracted DNA to achieve reproducible results.

Food Pathogen Testing

 

It is estimated that 1 in 6 people in the US get sick from food-borne diseases, and 3,000 people die every year as a result. Eating food contaminated with harmful pathogens, such as Salmonella or Listeria, is the main cause of illness. Therefore, testing food for pathogens is crucial for monitoring food safety. Advanced PCR-based methods are the fastest and most reliable ways to detect pathogens in food and require high-quality extracted DNA for precise, accurate results.

Food Authentication

 

Food identity testing is important for ensuring labeling accuracy; e.g., identifying the species present in a processed meat mixture or animal feed. PCR-based methods are an easy and accurate way to look for species-specific DNA sequences in food items. The choice of DNA purification method, as well as the choice of PCR targets, can greatly influence success in food analysis, depending on the specific foodstuffs and target DNA involved.

GMO Testing

 

The European Union (EU) and many other countries have policies for labeling or excluding products containing material from GMO. GMO testing confirms the amount of GMO present in plants, seeds or foods and ensures compliance with EU and global regulations. PCR-based GMO detection methods are commonly used and rely on high yields of DNA with high purity for reproducible performance.
