FSIS Announces Move from Pulsed-Field Gel Electrophoresis to Whole Genome Sequencing for Analyzing Shiga Toxin-Producing E. coli (STEC) and Salmonella Isolates

  Whole genome sequencing (WGS) determines the order of all of the DNA building blocks (nucleotides) in an organism’s entire genome in a single laboratory process.  A comparison of the DNA sequence of an isolated bacterial pathogen to the sequences from other samples in a DNA database can pinpoint the source of a foodborne disease … Continue Reading

CDC expands use of Whole Genome Sequencing in Foodborne Illness

Whole genome sequencing (WGS) provides insight into the genetic fingerprint of a pathogen by sequencing the chemical building blocks that make up its DNA and is increasingly being employed in food safety efforts. Since 2012, the U.S. Food and Drug Administration (FDA) has regularly turned to WGS to better understand foodborne pathogens, including identifying the … Continue Reading

FDA Pushes for Sharing Whole Genome Sequencing to Promote Food Safety

Whole genome sequencing (WGS) provides insight into the genetic fingerprint of a pathogen by sequencing the chemical building blocks that make up its DNA and is increasingly being employed in food safety efforts.  Since 2012, the U.S. Food and Drug Administration (FDA) has regularly turned to WGS to better understand foodborne pathogens, including identifying the … Continue Reading

FSIS to Host Meeting on Whole Genome Sequencing

Whole genome sequencing (WGS) provides insight into the genetic fingerprint of a pathogen by sequencing the chemical building blocks that make up its DNA and is increasingly being employed in food safety efforts.  Since 2012, the U.S. Food and Drug Administration (FDA) has regularly turned to WGS to better understand foodborne pathogens, including identifying the … Continue Reading

FDA Increasingly Using Whole Genome Sequencing to Achieve Food Safety Goals

As background, whole genome sequencing (WGS) essentially provides insight into the genetic fingerprint of a pathogen by sequencing the chemical building blocks that make up its DNA.  Since 2012, FDA has regularly turned to WGS to better understand foodborne pathogens, including identifying the nature and source of microbes that contaminate food and cause outbreaks of … Continue Reading

FDA Requests Comments on Foods Derived from Genome Edited Plants

As our readership is well aware, foods from genetically engineered (GE) plants must meet the same food safety requirements as foods derived from traditionally bred plants under the Federal Food, Drug, and Cosmetic Act.  As a routine premarket step, developers of new plant varieties, including those produced using genome editing, typically consult with FDA regarding … Continue Reading

FDA Works to Find Source of Multi-State Outbreak of E. coli Infections

On November 20, the Centers for Disease Control and Prevention (CDC), in conjunction with the Food and Drug Administration (FDA) and several state agencies, announced that it is currently investigating an outbreak of Shiga toxin-producing E. coli (STEC) O157:H7 infections that has so far impacted at least 17 people across 8 states. The first reported … Continue Reading

FDA Promotes Programs for Safe Use of Biotechnology

Drs. Susan Mayne, head of the Food and Drug Administration’s (FDA’s) Center for Food Safety and Applied Nutrition (CFSAN), and Dennis Keefe (head of CFSAN’s Office of Food Additive Safety) published a post on the FDA Voices blog on March 21 discussing FDA’s  Voluntary Plant Biotechnology Consultation Program (the Consultation Program) and the Plant and … Continue Reading

FDA Publishes Findings from Investigation of Romaine Lettuce E. coli Outbreak

As previously reported on this blog, in November 2018 FDA, in conjunction with the CDC, state officials, and Canadian food and public health officials, investigated an outbreak of E. coli O157:H7 infections in multiple US states and Canadian provinces. The investigation determined the cause of the outbreak was the consumption of contaminated romaine lettuce. Indeed, … Continue Reading

NGO Publishes Report on Food Safety

The United State Public Interest Research Group (PIRG) published “How Safe is Our Food? Recent trends and case studies, and what they mean for our health”, a review and commentary of the food safety system in the United States.  PIRG reviewed trends in food safety, with an emphasis on recalls, as well as case studies … Continue Reading
