USA – CDC: E coli outbreak sickens 17 in 7 states

Cidwrap

Though no source has been identified yet, the US Centers for Disease Control and Prevention (CDC) announced yesterday that federal and state health officials are investigating an Escherichia coli O157:H7 outbreak that has sickened 17 people in 7 states.

The outbreak includes infections recently reported by the New Jersey Department of Health (NJDH). The CDC emphasized that so far no specific food item, grocery store, or restaurant chain has been identified as the source of the outbreak, and local public health officials are still interviewing sick people to see what they ate or were otherwise exposed to the week before their symptoms began.

Some media outlets in New Jersey have reported that Panera Bread restaurants are part of a regional investigation into an E coli outbreak and that other chain restaurants could be involved.

Ireland – Woman died due to Salmonella after Communion function, inquest told

RTE

A woman who contracted food poisoning at a First Communion function died due to salmonella, an inquest has heard.

Investigations into the outbreak are continuing, an inquest into the death of 55-year-old mother of one Sandra O’Brien heard.

Ms O’Brien, from Rivervalley, Swords, Co Dublin died on 21 May, 2017 following the consumption of food prepared at O’Dwyer’s Bar and Grill, Strand Road, Portmarnock, Co Dublin.

Ms O’Brien’s husband, Garda Sgt Michael O’Brien, attended a short inquest hearing into her death at Dublin Coroner’s Court.

Investigations by two separate authorities are ongoing into the salmonella outbreak, the inquest heard.

Research – Effects of Bacterial Dose and Fly Sex on Persistence and Excretion of Salmonella enterica serovar Typhimurium From Adult House Flies (Musca domestica L.; Diptera: Muscidae)

Oxford Academic fly

Abstract

Salmonella Typhimurium (Le Minor and Popoff 1987; Enterobacteriales: Enterobacteriaceae) is a pathogen that causes gastroenteritis in humans and can be harbored by house flies. Factors influencing excretion of S. Typhimurium from infected flies have not been elucidated but are essential for assessing transmission potential. We determined the persistence and excretion of a green fluorescent protein (GFP) expressing strain of S. Typhimurium from house flies. Individual male and female flies were fed either sterile Luria-Bertani (LB) broth (controls) or cultures of “high” (~105 colony forming units [CFU]) or “low” (~104 CFU) doses of bacteria (treatments). Bacterial persistence was determined over 16 h by culturing whole-fly homogenate. Both sex and dose affected persistence between 6 and 12 h postingestion. In a separate experiment, fly excretion events were monitored during this time interval and excreta droplets were individually cultured for bacteria. Female flies had more excretion events than males across treatments. We observed interactions of fly sex and bacterial abundance (dose), both on the proportion of Salmonella-positive droplets and the CFU shed per droplet (CFU/droplet). In the low-dose treatment, males excreted a greater proportion of positive droplets than females. In the high-dose treatment, males excreted more CFU/droplet than females. High-dose male flies excreted more CFU/droplet than low-dose males, but low-dose females excreted more CFU/droplet than high-dose females. Irrespective of sex, low-dose flies excreted a greater dose-adjusted CFU (CFU droplet/CFU fed) than high-dose flies. This study demonstrates that both bacterial abundance and fly sex may influence excretion of bacteria from flies, and should be considered when assessing the risk of house fly transmission of pathogens.

RASFF Alert – Foodborne Uutbreak Scombroid Syndrome – Histamine- Frozen Sailfish

kswfoodworld food safety poisoning

RASFF-foodborne outbreak suspected (scombroid syndrome) to be caused by frozen salifish (Istiophorus albicans) from Spain in Italy.

Scombroid poisoning is a disease due to the ingestion of contaminated food (mainly fish). In scombroid poisoning, bacteria have grown during improper storage of the dark meat of the fish and the bacteria produce scombroid toxin. Scombroid toxin, or poison, is probably a combination of histamine and histamine-like chemicals. The toxin or poison does not affect everyone who ingests it.

No test is 100% reliable for assessing fish for this toxin or poison. Cooking kills the bacteria, but toxins remain in the tissues and can be absorbed after the food is ingested.

Susceptible fish include albacore, amberjack, anchovy, Australian salmon, bluefish, bonito, kahawai, herring, mackerel, mahi-mahi, needlefish, saury, sardine, skipjack, wahoo, and yellowfin tuna. Other fish and foods probably will be added to the list if testing systems for the poison improve. Affected fish may have a metallic or peppery taste.
