2009 journal article

Persistence of Human Noroviruses on Food Preparation Surfaces and Human Hands

FOOD AND ENVIRONMENTAL VIROLOGY, 1(3-4), 141–147.

By: P. Liu *, Y. Chien *, E. Papafragkou n, H. Hsiao*, L. Jaykus n & C. Moe *

author keywords: Norovirus; Real-time RT-PCR; Persistence; Environment
TL;DR: The results support the epidemiological evidence that food preparation surfaces and human hands can act as vehicles for human NoV transmission long after the initial contamination event has occurred. (via Semantic Scholar)

2007 journal article

Rapid and sensitive detection of hepatitis A virus in representative food matrices

JOURNAL OF VIROLOGICAL METHODS, 147(1), 177–187.

By: E. Papafragkou n, M. Plante *, K. Mattison*, S. Bidawid*, K. Karthikeyan*, J. Farber *, L. Jaykus n

author keywords: hepatitis A virus; food virology; viral extraction methods
MeSH headings : Animals; Cell Line; Disease Outbreaks; Food / virology; Hepatitis A / epidemiology; Hepatitis A virus / isolation & purification; Humans; Magnetics; Nucleic Acid Hybridization; Reverse Transcriptase Polymerase Chain Reaction; Sensitivity and Specificity
TL;DR: This is the first application of the automated magnetic capture technology to the concentration of viruses from foods, and it offers promise for facilitating the rapid detection of HAV from naturally contaminated products. (via Semantic Scholar)

INTERNATIONAL JOURNAL OF FOOD MICROBIOLOGY, 108(1), 84–91.

By: . DH D'Souza, A. Sair*, K. Williams  n, E. Papafragkou n, J. Jean *, C. Moore n, L. Jaykus n

author keywords: norovirus; feline calicivirus; persistence; transfer; food
MeSH headings : Calicivirus, Feline / growth & development; Calicivirus, Feline / isolation & purification; Calicivirus, Feline / physiology; Consumer Product Safety; Environmental Microbiology; Equipment Contamination; Food Contamination / analysis; Food Microbiology; Humans; Norovirus / growth & development; Norovirus / isolation & purification; Norovirus / physiology; RNA, Viral / analysis; RNA, Viral / isolation & purification; Reverse Transcriptase Polymerase Chain Reaction; Stainless Steel / analysis; Time Factors; Viral Plaque Assay
TL;DR: This study confirms lengthy NoV persistence on common food preparation surfaces and their ease of transfer, confirming a potential role for environmental contamination in the propagation of viral gastroenteritis. (via Semantic Scholar)

2006 journal article

Surrogates for the study of norovirus stability and inactivation in the environment: A comparison of murine norovirus and feline calicivirus

JOURNAL OF FOOD PROTECTION, 69(11), 2761–2765.

By: J. Cannon *, E. Papafragkou n, G. Park*, J. Osborne n, L. Jaykus n & J. Vinje *

MeSH headings : Animals; Caliciviridae / growth & development; Caliciviridae Infections / epidemiology; Caliciviridae Infections / virology; Cats; Disease Models, Animal; Gastroenteritis / epidemiology; Gastroenteritis / virology; Humans; Hydrogen-Ion Concentration; Mice; Norovirus / growth & development; Species Specificity; Temperature; Time Factors
TL;DR: The genetic relatedness of MNV-1 to human NoVs combined with its ability to survive under gastric pH levels makes this virus a promising and relevant surrogate for studying environmental survival ofhuman NoVs. (via Semantic Scholar)
