Less time, more safety: The chromogenic revolution in the control of Listeria monocytogenes

When evaluating foodborne pathogens, focusing solely on disease incidence risks overlooking one of the most dangerous: Listeria monocytogenes. Despite affecting only about 1,600 people a year in the U.S., more than 94% require hospitalization. Even with proper treatment, its high mortality rate (20%-30%) makes Listeria monocytogenes the deadliest foodborne pathogen.   

Given it's severity, Listeria spp is a major cause of food safety concern, often resulting in batch recalls and significant economic losses. Listeria is one of the most closely monitored microorganisms in the industry, as its outbreaks trigger strict intervention protocols that can bring production to a complete standstill. 

Occurrence of listeria in human health 

The genus Listeria includes more than 25 species, but only Listeria monocytogenes poses a threat to human health. Effective microbiological control requires high specificity to distinguish this pathogen from non-harmful species. Historically, achieving this distinction quickly, safely and accurately has been challenging.   

A Faster, More Accurate Solution   

In Alpha's new chromogenic culture media line, Listeria Chromogenic Agar Base (ALOA) ISO, a medium that can detect all species of Listeria (Listeria spp.) and identify Listeria monocytogenes. Formulated according to ISO 11290 and BAM M10a, it ensures efficacy and compliance with standardized laboratory protocols.   

Main advantages   

• Detects Listeria spp.  
• Identifies Listeria monocytogenes.   
• Complies with ISO 11290 and BAM M10a standards.   
• Reduces time and costs. 
• Provides results in 24-48 hours.

Our chromogenic culture medium provides a faster, more accurate and cost-effective solution for Listeria monocytogenes detection.
