Sequencing: The answer to a safer food supply worldwide

Sequencing, a useful DNA technology for organism characterization, has received additional recognition as an effective method to identify and subtype food pathogens.

Last month, a peer-reviewed article about the different methods for Salmonella characterization highlighted sequencing as a solid approach to identifying the pathogen.

U.S. FDA’s 2020 budget proposal highlights tech revolutions in food safety

Focusing on 2020 may feel premature when so much of 2019 lies ahead of us, but the U.S. Food and Drug Administration (FDA) has explained the rationale behind its 2020 budget proposals, and their points illustrate well the technological developments that are about to revolutionize food safety culture both within and outside of the U.S.

Genomics roundup: Understanding the science

In 2003, the Human Genome Project announced that it had officially completed its goal of sequencing the human genome. Since then, genomics has continued to explode in importance as a scientific subject, with potentially game-changing applications emerging in the medical field, agriculture, animal health, food safety and beyond.

The layman’s understanding of genomics, and how […]

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 sickens more than 550, leaves 36 dead in South Africa

A major outbreak of listeriosis has sickened more than 550 people in South Africa, with a reported 36 deaths due to the illness.

The large outbreak is highly unusual for the country. In a typical year, South Africa records just 60–80 cases of listeriosis. Authorities are currently investigating the source of this outbreak, which has […]

Nearly 100 salmonellosis cases linked to European eggs

It’s been a tough year for European egg shoppers. Millions of eggs were recalled in several countries after the harmful insecticide fipronil was discovered after the eggs were widely distributed to supermarkets. Seven countries have also reported salmonellosis outbreaks stemming from eggs.

At least 96 cases have recently been reported from Belgium, France, Luxembourg, the […]

The advantages of metagenomics over genome sequencing

Earlier this week, Neogen’s own Joe Heinzelmann was a special guest on Food Safety Magazine’s podcast, “Food Safety Matters.”

Heinzelmann dropped by to talk about metagenomics, next generation sequencing (NGS) and whole genome sequencing (WGS). This technology can help the food processing industry detect spoilage organisms within facilities, eliminate them, and reduce the possibility of […]

FDA’s GenomeTrakr supports food safety around the globe

There’s Twitter. Uber. Venmo. Facebook. The World Wide Web has brought us no shortage of apps, websites and networks with trendy names and useful functions. For the food industry, now there’s GenomeTrakr.

GenomeTrakr is a network of more than 60 laboratories across the world working in conjunction with the U.S. Food and Drug Administration (FDA). […]

Whole genome sequencing used to investigate Salmonella outbreak

The U.S. Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA), recently released a report on a 2016 Salmonella outbreak, identifying it to the public for the first time.

More than 30 people across nine U.S. states were sickened. Eight of those people were hospitalized, with victims spreading from Texas […]

Science: Salmonella serotyping using next-generation sequencing

Recently, there has been a lot of attention around next-generation sequencing—whole genome sequencing (WGS) in particular—for outbreak investigations. Neogen has posted a few articles on our blog and foodsafetytech.com to help articulate the applications of whole genome sequencing.

While whole genome sequencing is being used as a replacement for pulsed-field gel electrophoresis (PFGE), some companies […]
