Testing & Analysis
Testing & Analysis RSS FeedSubscribe

Testing and analysis help ensure food safety and quality by determining if pathogens, chemicals, or allergen residues are present in the processing environment or food products.

Topics

Air/Water Monitoring

Air and water monitoring involves the monitoring and testing of air and water quality in the processing line of a facility. Test results help determine if acceptable standards are being met for a range of parameters that influence food safety and quality.

Allergens

Allergen testing seeks to determine the presence of foods or food residues that are classified as allergens in foods or beverages that are not labeled as containing those foods. Class 1 allergens, which encompass the Big 9, are of the greatest concern in allergen testing.

Chemical

Chemical testing and analysis examine the artificial or undesired chemicals that may make their way into food and water, including those from agricultural practices, food processing, or packaging.

Environmental Testing

Environmental testing involves the microbiological sampling of food contact surfaces or nearby areas to test for the presence of pathogens or indicator organisms. An environmental monitoring program (EMP) includes pathogen swabbing to detect risk in the sanitary conditions of the processing environment and is a verification of the effectiveness of pathogen controls in place at a facility.

Laboratory Management

Laboratory management is concerned with the management of testing procedures, control measures for sampling, reporting of pathogen findings, and laboratory accreditation.

Methods

Testing and analysis methods include processes and procedures in use or under development for performing microbiological testing, product sampling, environmental monitoring, etc.

Microbiological

Microbiological testing seeks to identify the presence of bacterial pathogens, viruses, and parasites on food contact surfaces, in agricultural water and soil, and in food products. Frequent swabbing to determine if pathogens are present on food processing equipment is an important part of a sound environmental monitoring program (EMP) at a facility.

Sampling/Sample Prep

Sampling programs for food examine a certain portion or product units of a particular lot of the same food as a representative of the quality and safety of the food. Sample prep for laboratory testing involves the preparation of samples for testing.

February 15, 2023

Researchers have introduced a novel, thermal biosensor for real-time detection of Escherichia coli, demonstrating its ability to detect the pathogen in milk without sample preparation. The sensor would be easy to mass produce, and shows potential as a low-cost, rapid tool for onsite microbial indication.

A New Era for Food Allergen Analysis? Shifting Focus from Detection to Accurate and Precise Quantification

Method considerations and data gaps must be addressed in the shift toward quantitative, risk-based allergen management strategies
Melanie Downs Ph.D.
February 6, 2023

Risk-based approaches for food allergens offer a path forward for both allergen management and precautionary allergen labeling decision-making. After many years of research, a clearer picture has emerged of the population-level, threshold-dose distributions for major food allergens using data generated in double-blind, placebo-controlled food challenge studies. If the food allergen management field is headed for a shift toward quantitative, risk-based management strategies, however, then several method considerations and important data gaps must be addressed.

Should Nuts and Low-Moisture Foods Consider a New Sampling Approach?

Eric Wilhelmsen, Ph.D., C.F.S.
January 17, 2023

A pervasive trend exists to take larger and more frequent samples to address microbial contamination. This trend has touched almonds and is expected to hit other nut products, which can be considered for aggregated sampling as a solution.
