Research – Foodborne illness Outbreaks from Microbial Contaminants in spices, 1973–2010

Science Direct

This review identified fourteen reported illness outbreaks attributed to consumption of pathogen-contaminated spice during the period 1973–2010. Countries reporting outbreaks included Canada, Denmark, England and Wales, France, Germany, New Zealand, Norway, Serbia, and the United States. Together, these outbreaks resulted in 1946 reported human illnesses, 128 hospitalizations and two deaths. Infants/children were the primary population segments impacted by 36% (5/14) of spice-attributed outbreaks. Four outbreaks were associated with multiple organisms. Salmonella enterica subspecies enterica was identified as the causative agent in 71% (10/14) of outbreaks, accounting for 87% of reported illnesses. Bacillus spp. was identified as the causative agent in 29% (4/10) of outbreaks, accounting for 13% of illnesses. 71% (10/14) of outbreaks were associated with spices classified as fruits or seeds of the source plant. Consumption of ready-to-eat foods prepared with spices applied after the final food manufacturing pathogen reduction step accounted for 70% of illnesses. Pathogen growth in spiced food is suspected to have played a role in some outbreaks, but it was not likely a contributing factor in three of the larger Salmonella outbreaks, which involved low-moisture foods. Root causes of spice contamination included contributions from both early and late stages of the farm-to-table continuum.

38% of ill persons have been hospitalized, and no deaths have been reported.

Most ill persons (74%) have been reported from California.

Research – Listeria’s Resistance to Disinfectants

University of Veterinary Science- ViennaEurofins Food Testing UK

Listeria poses a significant risk to human health. The main transmission route involves meat and dairy products, so it is important to treat dairies and food-processing plants regularly with disinfectants to kill bacteria. Unfortunately, listeria is developing resistance to the compounds that are most frequently used. Recent work in the group of Stephan Schmitz-Esser at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) has uncovered the mechanism for listeria’s resistance to one such agent, benzalkonium chloride. The findings have been published in the online journal Plos One.

Research – Salmonella

Food Poisoning BulletinSalm

Salmonella is naturally occurring. In the wake of outbreaks, like the one linked to Foster Farms chicken, it’s an often-repeated phrase meant to assuage consumer fears and absolve corporate responsibility. But the phrase leaves out a key piece of information, where Salmonella naturally occurs.

Salmonella lives in the intestines of humans and other animals. It doesn’t “naturally occur” on the boneless, skinless chicken breasts or the wings and drumsticks you buy at the store. It gets there through a process of contamination. People can only get Salmonella infections when they eat or drink foods that have microscopic amounts of human or animal fecal matter on them.

Food Safety News

The mishandling or undercooking of raw chicken meat associated with the recent Foster Farms Salmonella outbreak has sickened nearly 340 people across 20 states and Puerto Rico since March and has caused concern among consumers, consumer groups, and food-safety advocates about the safety of our food system and the efficacy of testing systems designed to keep our nation’s food supply safe.

Currently, federal law under USDA allows for 7.5 percent of whole chicken carcasses to be contaminated with pathogenic bacteria such as Salmonella and Campylobacter. This means that products contaminated with Salmonella and Campylobacter have become common and are frequently shipped from production facilities to stores. It is up to the consumer to follow safe handling and cooking practices to avoid being sickened.

USDA Food Safety and Inspection Service guidelines require microbiological sampling to monitor raw poultry for harmful pathogenic bacteria such as Salmonella and Campylobacter, but the regulations are not necessarily enforceable because no strains of Salmonella and Campylobacter are classified as adulterants.

To date, one person has died and several others have been sickened in an outbreak of Legionnaires’ disease linked to Glenwood Nursing Home in Florence, Alabama. Legionnaires’ is a form of pneumonia caused by inhaling water mist containing Legionella bacteria.

All confirmed and suspected cases have been either residents or visitors to the nursing home. The one person who has died in the outbreak was a woman who visited the facility with two family members. She later developed respiratory symptoms and was hospitalized. Tests confirmed Legionnaires disease (Legionella pneumonia). The other family members were also sickened.

USA – Cyclospora Outbreak Update

Food Poisoning Journal

As of September 20, 2013 (5pm EDT), CDC has been notified of 643 ill persons with of Cyclospora infection from 25 states: Arkansas, California, Connecticut, Florida, Georgia, Illinois, Iowa, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York (including New York City), Ohio, Pennsylvania, South Dakota, Tennessee, Texas, Virginia, Wisconsin, and Wyoming.

Most of the illness onset dates have ranged from mid-June through mid-July.

Public health officials in Iowa and Nebraska performed investigations within their states and concluded that restaurant-associated cases of cyclosporiasis in their states were linked to a salad mix produced by Taylor Farms de Mexico.

Epidemiologic and traceback investigations conducted in Texas by state and local public health and regulatory officials, the FDA, and CDC indicated that some illnesses among Texas residents were linked to fresh cilantro from Puebla, Mexico.

UK – Scottish Nursery Children Ill with Salmonella

Evening Telegraph

Several children who attend the same Dundee nursery have been hit by salmonella.

Eight children at Technotots Nursery in Brunel Road, Wester Gourdie Industrial Estate, were struck down with the bacteria last month.

NHS Tayside’s health protection team, environmental health officers and Health Protection Scotland have been called in to identify the source of exposure. As yet the investigation has not revealed what caused the salmonella infections but the owner of Technotots denies it originated in the nursery.

The children involved were not believed to have been taken seriously ill.

An NHS Tayside spokeswoman said none had to be hospitalised as a result of their condition.
