Scientific Testing That Protects People and Strengthens Trade

The Testing Department provides laboratory analysis for food, water, beverages, agricultural produce, and related products to determine safety, quality, nutritional value, and regulatory compliance.

Core Laboratory Focus

What the Testing Department Supports

Nutritional composition and product labelling
Food and beverage safety verification
Water quality and public health protection
Regulatory compliance and market confidence

Safety

Detects harmful contaminants, microbes, toxins, and unsafe product conditions.

Quality

Supports shelf-life, product consistency, and production confidence.

Compliance

Helps businesses meet standards and regulatory requirements.

Trade Confidence

Builds trust between producers, regulators, traders, and consumers.

Food Chemistry Laboratory

Chemical Testing for Nutrition, Safety, and Product Quality

The Chemistry Laboratory analyzes food, water, beverages, and agricultural products to determine composition, contaminants, quality, and compliance.

Proximate Analysis

Determines primary food components including moisture, ash, crude fat, crude protein, crude fiber, and carbohydrates.

Water Analysis

Analyzes physical and chemical parameters to determine drinking water safety and environmental water quality.

Beverage Analysis

Assesses alcoholic and non-alcoholic beverages for quality, safety, authenticity, and nutritional value.

Proximate Analysis Laboratory

Nutritional Composition Testing for Food and Feed Products

Proximate analysis provides practical insight into nutritional profile, safety, quality, labelling information, feed formulation, and quality control.

H₂O

Moisture Analysis

Helps determine shelf life and food quality.

P

Crude Protein

Evaluates the nutritional quality of protein sources.

F

Crude Fat

Influences energy value and sensory properties of food.

Fi

Crude Fiber

Represents insoluble residue important for digestive health.

A

Ash Content

Represents the inorganic mineral fraction of the product or feed.

Specialized Chemistry Laboratories

Contaminant and Residue Testing Capacity

These laboratory areas support the analysis of toxins, metals, pesticide residues, veterinary drug residues, and active ingredients in products and agricultural produce.

Beverage Analysis

Testing for Beverage Quality, Safety, Authenticity, and Nutrition

A

Physicochemical Parameters

  • Alcohol by Volume and methanol
  • pH, total acidity, and volatile acidity
  • Specific gravity and density
  • Color and transparency
  • Dry matter contents
N

Chemical Composition & Nutritional Value

  • Sugars such as glucose, fructose, and sucrose
  • Proteins and nitrogen content
  • Vitamin C in fruit juices and non-alcoholic drinks
  • Sugar profiles, carbonation, caffeine, and preservatives
Food Microbiology Laboratory

Microbiological Analysis for Public Health and Product Safety

The Food Microbiology Laboratory analyzes food products, water, beverages, and related materials to determine microbial safety and quality.

DNA

GMO Testing

Tests genetically modified food using Real-Time PCR to detect genetic material that has been artificially altered.

F

Food Testing

Tests food samples for pathogens, spoilage organisms, toxins, aerobic plate counts, Salmonella, Listeria, and environmental swabs.

AMR

Antimicrobial Resistance

Detects, tracks, and characterizes resistant microorganisms entering the food chain, including resistant Salmonella, Campylobacter, and E. coli.

W

Water Microbiology

Identifies bacterial, viral, and parasitic contaminants and monitors drinking water quality for microbial safety.

B

Beverage Microbiology

Tests process water and finished beverage products for harmful microorganisms, spoilage organisms, and regulatory compliance.

ISO

Accreditation Direction

The laboratory is seeking ISO/IEC 17025 accreditation for yeast and moulds, as well as coliforms in water.

AMR

AMR Testing Role

The AMR laboratory supports food testing by identifying resistant microorganisms that may enter the food chain and threaten public health.

Detection of resistant bacteria in food products
Tracking of organisms linked to food processing and agriculture
Protection of consumers from resistant pathogens

One Health Contribution

01 Ensures ready-to-eat food products do not carry high levels of resistant bacteria.
02 Provides data to support policies on antibiotic use in agriculture in Liberia.
Water & Beverage Microbiology

Microbial Safety Testing for Water and Beverage Production

Water Testing Lab

Analyzes water samples for bacterial, viral, and parasitic contaminants to support public health safety, compliance, and environmental protection.

  • Legionella, Salmonella, Giardia, and Cryptosporidium
  • E. coli, total coliforms, and Enterococci
  • Routine drinking water quality analysis

Beverage Microbiology Lab

Ensures process water and finished products are safe, high quality, and free from harmful microorganisms that cause spoilage or health risks.

  • E. coli, Salmonella, Listeria, and Pseudomonas aeruginosa
  • Indicator organisms such as coliform bacteria
  • Total Plate Count, yeast, and mold testing
  • Process water quality and regulatory adherence
