The Health Department says it could have been passed on any number of ways.

UK – Seven people struck by food poisoning but public health body refuses to name restaurant it closed down – Campylobacter

Wales Online

A public health body says it will not name a Cardiff restaurant at the centre of a food poisoning outbreak.

Public Health Wales says it is “satisfied” that the situation – which led to seven people being confirmed with the campylobacter infection – has been dealt with and there is “no risk to public health.”

The victims ate at the restaurant during the weekend of May 16, and two people are also suspected to have the infection.

Research – A large Great Britain-wide outbreak of STEC O157 phage type 8 linked to handling of raw leeks and potatoes – 2011

Cambridge Journals

Between December 2010 and July 2011, 252 cases of STEC O157 PT8 stx1 + 2 infection were reported in England, Scotland and Wales. This was the largest outbreak of STEC reported in England and the second largest in the UK to date. Eighty cases were hospitalized, with two cases of haemolytic uraemic syndrome and one death reported. Routine investigative data were used to generate a hypothesis but the subsequent case-control study was inconclusive. A second, more detailed, hypothesis generation exercise identified consumption or handling of vegetables as a potential mode of transmission. A second case-control study demonstrated that cases were more likely than controls to live in households whose members handled or prepared leeks bought unwrapped [odds ratio (OR) 40, 95% confidence interval (CI) 2·08-769·4], and potatoes bought in sacks (OR 13·13, 95% CI 1·19-145·3). This appears to be the first outbreak of STEC O157 infection linked to the handling of leeks.

Hong Kong – Raw Sheeps Milk Cheese – Listeria monocytogenes

CFS

Food Alert – (*updated on 5 June 2015) French raw sheep’s milk cheese suspected to be contaminated with Listeria monocytogenes

<!–

–>

Issue Date 2015-05-07
Source of Information Notification from the Rapid Alert System for Food and Feed (RASFF) of the European Commission
Food Product Raw sheep’s milk cheese
Name of Importer
Product name and Description Product name: Raw milk cheese from sheep “PERAIL”
Place of origin: France
Manufacture date: between March 15 and April 2, 2015
Best before dates: May 23, 29 or 30, 2015
Reason For Issuing Alert

– The Centre for Food Safety (CFS) received a notification from the RASFF that certain batches of PERAIL raw sheep’s milk cheese were found to have been contaminated with Listeria monocytogenes. The French producer concerned has initiated a recall of all batches of all specialties of the product produced between the aforesaid dates. According to the information provided by the RASFF, a small volume of the affected product has been imported into Hong Kong.

– Listeria monocytogenes can be easily destroyed by cooking but can survive and multiply at refrigerator temperature. Most healthy individuals do not develop symptoms or only have mild symptoms like fever, muscle pain, headache, nausea, vomiting or diarrhoea when infected. However, severe complications such as septicemia, meningitis or even death may occur in newborns, elderly and those with a weaker immune system. Although infected pregnant women may just experience mild symptoms generally, the infection of Listeria monocytogenes may cause miscarriage, infant death, preterm birth, or severe infection in the newborns.

*Updated information on 5 June 2015:

– On 4 June 2015, CFS received updates from The Ministry of Agriculture of the Republic of France that the notification was withdrawn because the bacteria detected in the cheese concerned had been proven to be Listeria ivanovii, which does not justify the conclusion that these products are dangerous according to European regulations. The recalled products were therefore returned to the market. Listeria ivanovii is known to cause disease predominantly in ruminants.

Information – CDC PulseNet

CDC –

PulseNet connects cases of foodborne illness to potential outbreaks. PulseNet is a national laboratory network  made up of 87 laboratories−at least one in each state. PulseNet  connects foodborne illness cases together to detect and define outbreaks using DNA “fingerprinting” of the bacteria making people sick  using a standardized process called pulsed-field gel electrophoresis (PFGE). Every state has at least one public health laboratoryExternal Web Site Icon that can match up bacteria from sick people in many different locations using PulseNet’s DNA fingerprinting technique and database. PulseNet tracks what is being reported to CDC today compared to what was reported in the past to look for changes. This means that PulseNet keeps a cumulative database representing nearly half a million isolates of bacteria from food, the environment, and human foodborne illness.

Since its beginning in 1996, PulseNet has revolutionized the detection and investigation of foodborne disease outbreaks, especially in multiple sites across the country which, before PulseNet, often went undetected or were detected only after they grew very large.

Foodborne Outbreak Investigations

When two or more people get the same illness from the same contaminated food or drink, the event is called a foodborne disease outbreak. The list on this page primarily represents multistate foodborne outbreak investigations since 2006 where CDC was the lead public health agency. For a complete listing of reported outbreaks please use the Foodborne Outbreak Online Database (FOOD) tool.

Public health officials investigate outbreaks(http://www.cdc.gov/foodsafety/outbreaks/investigating-outbreaks/investigations/index.html) to control them, so more people do not get sick, and to learn how to prevent similar outbreaks(http://www.cdc.gov/foodsafety/outbreaks/prevention-education/future.html) from happening in the future.

USA – Homeless Shelter Food Illness Outbreak Likely to be Staphylococcus aureus Toxin

SLCHD Staph

The Salt Lake County Health Department (SLCoHD) has determined that a food item served Sunday night at the St. Vincent de Paul Dining Hall contained Staphylococcal enterotoxin, a common cause of foodborne illness that produces symptoms consistent with those reported by the affected individuals.

The toxin is caused by Staphylococcus aureus, a common bacteria found on the skin that does not usually cause illness—unless it is introduced into improperly heated or cooled food. Staph bacteria are most often introduced into food when food handlers touch food with their bare hands. If that food is within the “food danger zone” of 40° F to 140° F, the bacteria can then grow and produce the toxin.

USA-Raw Goats Milk Linked to Three in California with Campylobacter

Food Poisoning Bulletin

Orange County has confirmed three cases of campylobacteriosis infection associated with consumption of raw goat milk distributed by Claravale Farm of San Benito County, California.  All three patients are young children less than 5 years of age.  One patient was hospitalized, and all of them are expected to recover.

The raw goat milk was distributed throughout the state, and the California Department of Public Health (CDPH) is leading an investigation to determine if there are additional cases.  While the CDPH investigation is ongoing the Health Care Agency advises against consuming Claravale Farm raw goat milk.
