Salmonella Testing

Salmonella species are pathogenic Gram-negative bacteria associated with serious foodborne and product contamination risks. Their presence in pharmaceutical and nutritional products is strictly prohibited under global pharmacopeial requirements.

Tests We Offer

Pharmaceutical Products (USP <62>)

Salmonella spp. — Specified Microorganism (USP <62>)

Salmonella species are Gram-negative pathogenic bacteria that must be absent in specified non-sterile pharmaceutical products. Their presence indicates serious contamination from raw materials, water, or environmental sources.

Test Methodology (USP <62>)

Testing follows a multi-stage enrichment and isolation workflow:

• Non-selective pre-enrichment to recover injured organisms
• Selective enrichment in Salmonella-promoting broths to suppress competing flora
• Isolation on selective/differential agar media
• Biochemical and serological confirmation of presumptive colonies

This workflow ensures sensitive detection even at very low contamination levels.

Dietary Supplements & Nutritional Products (USP <2022>)

Salmonella spp. — USP <2022> Absence Requirement

Under USP <2022>, Salmonella must be absent in dietary supplements due to its high pathogenic risk.

Test Methodology (USP <2022>)

• Sample homogenization and preparation for representative testing
• Pre-enrichment step in non-selective media
• Selective enrichment incubation to promote Salmonella recovery
• Isolation on selective agar plates
• Confirmatory biochemical and/or serological identification

This method is designed for complex botanical and nutritional matrices.

Benefits

• Ensures consumer safety and regulatory compliance
• Detects contamination in raw materials
• Supports GMP manufacturing validation
• Prevents product recalls and regulatory action
