Neogen launches Listeria Right Now™ for 2-hour Listeria verification
Unlike traditional methods that take 24 to 48 hours, Listeria Right Now delivers results within two hours for same-day verification and response.
U.S.A. — Neogen Corporation has launched Molecular Detection Assay – Listeria Right Now™, a rapid, enrichment-free solution for detecting Listeria species in the environment.
With results in just two hours, Listeria Right Now helps enable food safety professionals to make faster, more informed sanitation decisions without compromising accuracy or requiring complex laboratory infrastructure.
“When it comes to Listeria, every hour counts. Listeria Right Now was designed to give food safety teams answers fast enough to act before a risk becomes a recall,” said Dr. Jason Lilly, Chief Scientific Officer at Neogen.
“The method is precise, practical, and easy to deploy. We’re excited to show how it can strengthen environmental monitoring programs in real-world settings,” Dr. Jason added.
Mode of operation
Listeria Right Now pairs a user-friendly sample collection device, uniquely designed to swab various surface types, including areas up to 12″ x 12″ and reach into narrow cracks and crevices, with an innovative reagent system.
No enrichment is required, enabling same-day verification and corrective response within two hours. It streamlines the detection process, allowing the interventions to occur within the same production shift.
Each reaction tube includes blue, color-coded pellets with all necessary detection reagents, which reconstitute easily when pipetted to streamline workflow and enhance consistency.
Listeria Right Now is powered by Neogen’s Molecular Detection System, which features intuitive software, color-coded assays for better tracking, and the ability to test up to 96 samples per run.
Industry application
The system supports simultaneous testing across multiple qualitative assays, enabling labs to maintain workflow flexibility without added complexity.
Traditional Listeria detection methods often require 24 to 48 hours and may involve multiple tools depending on surface type and testing needs. For processors in dairy, produce, beef, and ready-to-eat segments, these delays can disrupt workflows and elevate contamination risk.
Built for global applicability, Listeria Right Now offers a practical, high-impact solution for diverse food production environments worldwide, while also supporting the evolving regulatory expectations around Listeria monitoring in the U.S.
Live Demonstrations at IAFP 2025
Neogen will be showcasing Listeria Right Now at the 2025 International Association for Food Protection (IAFP) Annual Meeting, taking place July 27–30 at the Huntington Convention Center in Cleveland, Ohio, at Booth #511.
Attendees can experience live demonstrations and speak with Neogen experts about how the system complements the company’s broader food safety diagnostics portfolio.
