Case study: Dip manufacturer reduces Listeria positive rates to under 0.5% using Listeria Right Now

Listeria, as one of the most dangerous foodborne pathogens, poses a risk to consumer health as well as a company’s brand. It’s one of the most persistent food safety concerns faced by the food manufacturing industry today. Because of the lethality of this pathogen, many companies hold product until traditional lab tests determine the product […]

European Listeria outbreak blamed on frozen corn

It’s been three years since a deadly listeriosis outbreak started in Europe, and outbreak investigators have said they’ve likely hammered down the cause: frozen corn.

An investigation report published last week by the European Food Safety Authority and the European Centre for Disease Prevention and Control said that frozen corn is the most likely source […]

Listeria in Polish salmon likely from environmental contamination

A listeriosis outbreak from contaminated salmon earlier this year has been identified as a probable case of environmental contamination, according to experts.

The implicated salmon was processed in Poland and sold primarily in Denmark, and Listeria monocytogenes from the same isolate as the Danish outbreak was later found at a French retailer. Genetically linked isolates […]

Listeria Right Now™: top questions about its technology

Neogen has received a lot of questions since introducing the Listeria Right Now™ system this past July at the International Association for Food Protection’s annual meeting. The system is an environmental Listeria test that features molecular-level accuracy with no need for enrichment. The total time to result? Under one hour.

We’ve seen many different ways […]

Vectoring — a formal approach to tracking the sources and flow of pathogens in a facility

Pathogenic bacteria can infiltrate a facility from several different sources, including the external environment, people, equipment and raw materials. Once inside, pathogens can become established in harborage areas and carried to food production surfaces through a vector. Liquids, air, people and physical objects, such as carts or tools, are common vectors for pathogen transmission. It’s […]

Draft guidance addresses Listeria testing for RTE food production

Ready-to-eat (RTE) food producers were given new direction from the U.S. Food and Drug Administration (FDA) this year when its draft guidance “Control of Listeria monocytogenes in Ready-To-Eat Foods” was updated.

We’ve summarized the draft guidance before, but now we’ll go over the guideline’s approach to sampling and testing for L. mono.

Neogen develops fastest Listeria test with no enrichment

Neogen Corporation has developed an innovative test that detects Listeria in environmental samples in under 60 minutes — without the need to enrich samples.

Neogen’s new Listeria Right Now™ test system can detect all species of Listeria, including the pathogenic L. monocytogenes, in under 60 minutes through their ribosomal RNA (rRNA). The system’s effectiveness has […]

Science: Gut bacteria may protect from Listeria

To food industry sanitation experts, there isn’t a term much scarier than “Listeria.” Especially lately, “Listeria monocytogenes.” Scores of recall notices hit the news on a regular basis.

The bacteria can cause severe illness in people who eat food contaminated with it, and causes great difficulties for food producers. It’s a hardy, adaptable organism that […]
