Ingenta Studies – High Pressure E.coli/Campylobacter – Essential Oils E.coli/Salmonella

Posted on March 8, 2012 by | Leave a comment

Ingenta High Pressure

This study evaluated the high pressure inactivation of Campylobacter jejuni, Escherichia coli, and poultry meat spoilage organisms. All treatments were performed in aseptically prepared minced poultry meat. Treatment of 19 strains of C. jejuni at 300 MPa and 30°C revealed a large variation of pressure resistance.

Ingenta Essential Oils

The efficacy of cinnamaldehyde and Sporan for reducing Escherichia coli O157:H7 and Salmonella on spinach leaves was investigated. Spinach leaves were inoculated with a five-strain cocktail of Salmonella or E. coli O157:H7, air dried for ca. 30 min, and then immersed in a treatment solution containing 5 ppm of free chlorine, cinnamaldehyde, or Sporan (800 and 1,000 ppm) alone or in combination with 200 ppm of acetic acid (20%) for 1 min or with water (control).

Ingenta

This study was undertaken to examine the effect of ultrasound in combination with chlorine on the reduction of Escherichia coli O157:H7 populations on lettuce coring knives. Two new coring devices designed to mitigate pathogen attachment were fabricated and evaluated.

Laboratory Detection of ‘Toxic’ E.coli Increases

Posted on March 3, 2012 by | Leave a comment

Food Poisoning Bulletin

Enhanced laboratory detection of non-O157:H7 types of E. coli from stool samples of the sick is causing a surge in positive findings for toxic E. coli that is exponentially larger than the number of labs adopting the enhanced methods, a study by a Washington State Department of Health has found.

Washington State disease trackers looked at laboratories in Washington and examined the rate of non-O157 E. coli detection as more and more labs developed the tools to test for varied STECs. According to a summary of the research published this week by the Centers for Disease Control and Prevention (CDC), the number of laboratories in Washington State that tested for varied STECs increased from 2 (4 percent) in 2005 to 19 (33 percent) in 2010.

Four serogroups accounted for more than 80 percent of non-O157 STEC case findings. They were E. coli O26, E. coli O103, E. coli O121 and E. coli O111.

Hamburg EHEC E.coli O157 – Four More Cases

Posted on March 1, 2012 by | Leave a comment

Four new EHEC illnesses have occurred in Hamburg. Enterohaemorrhagic Escherichia coli (EHEC) had been found in an 11 boy and a 3-year old kindergarten child. Also two women aged  68 and 88  in the borough Altona were diagnosed early last week with the same organism.

The two infected children are from Blankenese and were taken ill last week. The boy may have visited also the same school as a six-year girl who had died about two weeks ago.

EHEC serotype O157 was isolated from the girl that had died.

Mobile Phone Detection of E.coli?

Posted on February 24, 2012 by | 1 comment

Bites

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have developed a new cell phone–based fluorescent imaging and sensing platform that can detect the presence of the bacterium Escherichia coli in food and water. The engineers combined antibody functionalized glass capillaries with quantum dots (semiconductors often used for medical imaging) as signal reporters to specifically detect E. coli particles in liquid samples using a lightweight, compact attachment to an existing cell-phone camera.

CIFA – Beef Product Recall – E.coli O157

Posted on February 19, 2012 by | Leave a comment

CIFA

The Canadian Food Inspection Agency (CFIA) and New Food Classics are warning the public not to consume certain Country Morning Beef Burgers, and no name Club Pack Beef Steakettes described below, because the products may be contaminated with E. coliO157:H7.

The Country Morning Beef Burgers product has been distributed to COOP and TGP grocery stores in British Columbia, Alberta, Saskatchewan, Manitoba, and Northwest Territories.

There has been one reported illness associated with the consumption of this product.

Food contaminated with E. coli O157:H7 may not look or smell spoiled. Consumption of food contaminated with these bacteria my cause serious and potentially life-threatening illnesses. Symptoms include severe abdominal pain and bloody diarrhoea. Some people may have seizures or strokes and some may need blood transfusions and kidney dialysis. Others may live with permanent kidney damage. In severe cases of illness, people may die.

More E. coli Research

Posted on February 17, 2012 by | Leave a comment

Food Safety News

In the wake of the devastating European E. coli outbreak linked to sprouts that killed at least 50 people and sickened more than 4,000, experts from the European Union and the United States are calling for new research on how to combat toxic strains of E. coli.
 
In November of 2011, 4 months after the outbreak ended, an international group of public health officials, medical professionals, epidemiologists, microbiologists and environmental scientists met to determine what lessons can be drawn from this epidemic. The results of this summit were released Thursday in Eurosurveillance. 
 
The group determined that more needs to be learned about shiga toxin-producing E. colis (STECs) such as E. coli O104:H4, the strain responsible for the European outbreak.
