Research -Campylobacter jejuni in Musca domestica: An examination of survival and transmission potential in light of the innate immune responses of the house flies.

Pub Med fly

The house fly, Musca domestica, has been implicated as a vector of Campylobacter spp., a major cause of human disease. Little is known whether house flies serve as biological amplifying hosts or mechanical vectors for Campylobacter jejuni. We investigated the period after C. jejuni had been ingested by house flies in which viable C. jejuni colonies could be isolated from whole bodies, the vomitus and the excreta of adult M. domestica and evaluated the activation of innate immune responses of house flies to ingested C. jejuni over time. C. jejuni could be cultured from infected houseflies soon after ingestion but no countable C. jejuni colonies were observed > 24 hours post-ingestion. We detected viable C. jejuni in house fly vomitus and excreta up to 4 hours after ingestion, but no viable bacteria were detected ≥ 8 hours. Suppression subtractive hybridization identified pathogen-induced gene expression in the intestinal tracts of adult house flies 4-24 hours after ingesting C. jejuni. We measured the expression of immune regulatory (thor, JNK, and spheroide) and effector (cecropin, diptericin, attacin, defensin and lysozyme) genes in C. jejuni-infected and -uninfected house flies using quantitative real time PCR. Some house fly factor, or combination of factors, eliminates C. jejuni within 24 hours post-ingestion. Because C. jejuni is not amplified within the body of the housefly, this insect likely serves as a mechanical vector rather than as a true biological, amplifying vector for C. jejuni, and adds to our understanding of insect-pathogen interactions.

Food Poisoning Bulletin

TreeHouse Foods is voluntarily recalling many products that contain sunflower seeds, which may be contaminated with Listeria monocytogenes bacteria. No illnesses have been reported to date, but listeriosis, the illness caused by this pathogenic bacteria, can take up to 70 days to appear.

FDA

SunOpta is voluntarily recalling a limited number of sunflower kernel products that have the potential to be contaminated with Listeria monocytogenes , an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, listeria infection can cause miscarriages and stillbirths among pregnant women.

Food Safety News

About 100 different snack products including brands such as Planters, Great Value, Meijer, Publix, Roundy and HyVee are being recalled nationwide because of possible Listeria contamination related to sunflower seeds.

The company supplies retailers and food service operations across North America. In February it completed acquisition of ConAgra Private Brands, according to its website.

USA -FDA NARMS Retail Meat Interim Report for Salmonella Shows Encouraging Early Trends Continue; Includes Whole Genome Sequencing Data for the First Time

FDA iStock_000012710183Small

The U.S. Food and Drug Administration has released a new interim report that measures antimicrobial resistance in Salmonella isolated from raw retail meat and poultry collected through the National Antimicrobial Resistance Monitoring System (NARMS). The 2014-2015 Retail Meat Interim Report contains data from January 2014 – June 2015. It focuses only on Salmonella, a major pathogen of concern in foodborne disease outbreaks. Information includes serotype distribution, prevalence by food source and state, selected resistance patterns, and a list of all the identified antimicrobial resistance genes. To provide data in a timelier manner, the FDA intends to issue retail meat interim reports twice per year. In this report FDA also includes, for the first time, whole-genome sequencing data for Salmonella as a new component of routine NARMS surveillance practices and has placed all the isolate-level data on its website.

NARMS was established in 1996 as a partnership between the FDA, the Centers for Disease Control and Prevention, and the U.S. Department of Agriculture to track antibiotic resistance in foodborne bacteria for drugs that are considered important in human medicine, including whether they are multidrug resistant (resistant to three or more classes of antibiotics). NARMS is critically important for monitoring trends in antimicrobial resistance among foodborne bacteria collected from humans, retail meats and food animals. In particular, it assists the FDA in making data-driven decisions on the approval of safe and effective antimicrobial drugs for animals.

The retail meat arm of the NARMS program collects samples of grocery store chicken, ground turkey, ground beef and pork chops, and tests for non-typhoidal Salmonella, Campylobacter, Escherichia coli and Enterococcus, to determine whether such bacteria are resistant to various antibiotics used in human and veterinary medicine. Enterococcus and most E. coli are not considered major foodborne pathogens but are included because they are helpful in understanding how resistance occurs and spreads.

Consumers can help protect themselves from foodborne bacteria, including antibiotic-resistant bacteria, by following four basic food safety tips: clean, separate, cook, chill. Learn more at http://www.foodsafety.gov/keep/basics/.
