Food Testing Methods Approved by the FDA

Chemical Analytical Manual (CAM) Methods

You use CAM methods to check for chemicals in food. These methods help you find harmful substances and make sure food is safe. CAM methods cover a wide range of tests. Some of the most common FDA-approved Food Testing methods include:

• Detection and quantitation of acrylamide in foods
• Determination of benzene in soft drinks and other beverages
• Analytical methods for testing products believed to contain ephedrine alkaloids, often found in botanical and dietary supplements
• Determination of furan in foods
• Rapid determination of perchlorate anion in foods by ion chromatography–tandem mass spectrometry, which you can use for Fruits, vegetables, milk, low moisture foods, infant foods, and water
• Method for determination of melamine and cyanuric acid residues in foods using LC-MS/MS, especially for animal tissue and milk-based infant formula

These methods help you detect both common and rare contaminants. You can trust CAM methods because the FDA reviews and updates them regularly.

Bacteriological Analytical Manual (BAM) Procedures

You rely on BAM procedures to find bacteria, viruses, and other microorganisms in food. These procedures help you protect people from foodborne illnesses. BAM procedures guide you through sample collection, preparation, and analysis. You can use them for many types of food, such as dairy, seafood, produce, and processed foods.

BAM procedures use different tools and tests. You might use culture methods to grow bacteria or rapid tests to find pathogens quickly. These procedures help you confirm if food is safe to eat. You can follow BAM steps to get accurate results every time you do Food Testing.
Tip: Always follow the latest BAM edition to stay up to date with new pathogens and improved testing techniques.

Elemental Analysis Manual (EAM) Techniques

You use EAM techniques to measure heavy metals and other elements in food. These techniques help you find dangerous substances like arsenic, cadmium, and lead. EAM methods use advanced tools, such as inductively coupled plasma mass spectrometry (ICP-MS), to give you precise results.

Here is a table showing the detection limits for some heavy metals using EAM techniques:

Heavy Metal	LOD (ppb)	LOQ (ppb)
Arsenic	1.3	11.6
Cadmium	0.4	3.7
Lead	1.2	10.9

You can compare EAM techniques with other elemental analysis methods. The table below shows how different methods detect elements and their sensitivity:

Method	Detectable elements	Sensitivity
ICP-OES/MS/SFMS	Li to U	ppm to ppt
AAS	Mainly metallic elements, up to 70	ppm
CHNOS	C, H, N, O, S	0.05–0.1 wt%
XRF	Be to U	10 ppm–1 at%
SEM-EDX	All except H, He, and Li	0.1–1 at%
ERDA	H to U	0.1–0.5 at.%
RBS	Be to U	0.1 at%

You can see that EAM techniques, especially ICP-MS, offer high sensitivity. This helps you detect even tiny amounts of harmful metals during Food Testing.

DNA-Based and PFAS Testing Methods

You use DNA-based methods to find bacteria and viruses in food. Polymerase chain reaction (PCR) is the most popular DNA-based test. In 2023, PCR made up 37.4% of the market share for Food Testing. You can use PCR to test dairy, meat, poultry, seafood, processed foods, and beverages. PCR helps you find pathogens quickly and accurately.

You also need to test for per- and polyfluoroalkyl substances (PFAS) in food. PFAS are chemicals that can harm health. Recent advances in high-performance liquid chromatography (HPLC) have made PFAS testing more effective. New column materials and high-resolution mass spectrometry help you find PFAS at very low levels. Improved sample preparation, like solid-phase extraction, increases recovery rates and reduces errors. These improvements help you get reliable results when you test for PFAS in complex foods.
Note: Using the right DNA-based and PFAS testing methods helps you meet FDA standards and keep food safe for everyone.

Food Testing and the FDA Regulatory Framework

Key FDA Standards and Guidelines

You need to follow strict rules when you test food in your laboratory. The FDA sets standards to make sure your results are accurate and reliable. The Laboratory Accreditation for Analyses of Foods (LAAF) Program is one important rule. This program tells you how to get your laboratory accredited and what you must do to meet FDA requirements. You must use a LAAF-accredited laboratory for certain situations, like import alerts or food safety problems. The FDA checks these laboratories to make sure they follow the rules and give correct results.
