WDRB – Notre Dame Norovirus Outbreak

The University of Notre Dame says Indiana State Department of Health lab tests confirm a norovirus cause of an outbreak of gastrointestinal illness that affected more than 100 youths taking part in sports camps.

The university said Saturday it received that news from St. Joseph County Health Officer Dr. Thomas Felger.

Notre Dame says a norovirus is very contagious and the most common “stomach bug” in the United States. It says the specific reason for the outbreak at Notre Dame remains unknown.

Finland – Two Children Sick – E.coli EHEC – Raw Milk

This is the translation from Finnish.

 Southwest Finland, a native of the four year old child was brought on Monday, 18.6. the next day he was diagnosed with EHEC (enterohaemorrhagic E. coli)-induced severe symptomatic infection. The child was forced to ICU care, but is already recovering from their illness.  Infection is suspected as the source actually purchased directly from the farm to a Finnish non-pasteurized milk (raw or tinkimaito). Another 1.5-year-old child has also been found with EHEC infection. This child had also consumed non-pasteurized milk. His illness did not required hospitalization. In addition three other people are suspected of being infected after drinking non-pasteurised milk.

 

Research – Campylobacter Cross Contamination in Abattoirs

NCBI MedPub 

Consumption of raw or undercooked poultry products contaminated with Campylobacter has been identified as a risk factor for human campylobacteriosis. We determined whether slaughtering of Campylobacter-positive flocks was associated with contamination of chicken products derived from Campylobacter-negative flocks slaughtered at the same abattoir. The presence of Campylobacter was investigated in 22 broiler farms 1 week prior to slaughter and in one abattoir on nine separate slaughter days. A total of 600 bulk packed chicken products were tested, with 198 (33.0%) of the products found to be Campylobacter positive. Of the 350 chicken products originating from Campylobacter-positive flocks, 180 (51.1%) were contaminated with the bacteria. In contrast, only 18 (7.2%) of 250 chicken products derived from Campylobacter-negative flocks were contaminated. In 14 of these 18 products, the Campylobacter isolates were identical to isolates obtained from the flock slaughtered immediately prior to the Campylobacter-negative flock. Notably, on 4/6 slaughter days, Campylobacter-negative flocks were slaughtered prior to the positive flocks, and Campylobacter was absent from all chicken products originating from the negative flocks. These results suggest that implementation of logistic slaughter (where Campylobacter-negative flocks are slaughter first) significantly decreases the prevalence of Campylobacter-positive chicken products.

Research – Rapid Cooling of Eggs and Food Safety

Science Daily

Taking just a few seconds to cool freshly laid eggs would add weeks to their shelf life, according to a Purdue University study.

The rapid-cooling process, developed by Kevin Keener, a professor of food science, uses liquid carbon dioxide to stabilize the proteins in egg whites so much that they could be rated AA — the highest grade for eggs — for 12 weeks. Earlier research showed that the same cooling technology could significantly reduce occurrences of salmonella illnesses

US – Organic Alfalfa Sprouts Salmonella Recall

FDA

As a precautionary measure, Banner Mountain Sprouts is voluntarily recalling organic sprouts under the following names: 4oz. zesty greens, 5oz. sprout salad, 4oz. clover, 2lb. clover, 4oz. alfalfa/broccoli, 4oz. alfalfa sprouts, and 1lb. & 2lb. alfalfa sprouts because they may be contaminated with salmonella. Routine testing showed signs of salmonella and Banner Mountain Sprouts was notified of possible contamination.

Salmonella is a bacterium that can cause an acute infection that can have symptoms such as diarrhea, fever and vomiting. Symptoms usually develop within one to four days after eating contaminated food. Most cases resolve without the need for medical attention. However, some individuals develop a serious illness that can lead to hospitalization.

The sprouts were distributed through retail stores and wholesalers in California. The products come in a 4 or 5 oz. clear, plastic, clamshell container and a 1lb. or 2lb. ziplock bag with a sell by date from 6/17/12 to 7/6/12. No illnesses have been associated with any Banner Mountain sprouts.

US – Multistate Salmonelle Montevideo – Live Poultry

Food Safety News

At least 66 people have fallen ill in 20 states in a Salmonella Montevideo outbreak linked to live poultry from a Missouri hatchery, the U.S. Centers for Disease Control and Prevention reported Monday. Sixteen people have been hospitalized while one infected person in Missouri has died, though Salmonella infection was not considered a contributing factor to the person’s death.

Live poultry, such as baby chicks and ducklings, can transmit Salmonella to humans via direct contact. The CDC advises not to kiss or snuggle live poultry and not to let children handle them. Those who do handle live poultry should wash their hands immediately afterwards.
 
This is the second outbreak associated with live poultry this year in the USA.
 
 

Hong Kong – Two Fatal Cases – Vibrio vulnificus

Center for Health Protection

The Centre for Health Protection (CHP) of the Department of Health is investigating two fatal cases of Vibrio vulnificus infection, with one of them causing necrotising fasciitis (flesh-eating disease).
The case of necrotising fasciitis caused by Vibrio vulnificus affected a 48-year-old man with underlying medical conditions who lived in Shenzhen
His clinical diagnosis was necrotising fasciitis and bilateral above-knee amputations were performed. His condition continued to deteriorate and he passed away yesterday (June 19).
The patient’s blood culture grew Vibrio vulnificus and his tissue and wound swabs also detected Vibrio vulnificus.
 The case of Vibrio vulnificus infection involved a 61-year-old man with chronic illness who lived in Yuen Long. He developed fever since June 16 and loss of consciousness on June 17. He was admitted to Pok Oi Hospital on the same day. His condition deteriorated and he passed away on June 18.
His blood specimen taken during his admission yielded Vibrio vulnificus.
 The CHP’s investigation revealed that the patient had consumed raw mantis shrimp
