USA/Canada – USDA Recall – Prosciutto – Listeria monocyotgenes

USDAFood Testing

Santa Maria Foods, a Brampton, Ontario, establishment, is recalling approximately 2,600 pounds of whole boneless ham prosciutto product due to possible contamination with Listeria monocytogenes, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The ham product was shipped to California and Michigan for further distribution. Case labels bear the Canadian establishment number “473A” within the Canadian mark of inspection. The following product is subject to recall: [Labels]

  • Approximately 50-lb. boxes labeled “PROSCIUTTO x 4 GOLD” with the case codes BR031356 or BR031374, produced on Nov. 14 and Nov. 15, 2013. Each box contains 4 individually packaged hams with the case codes BR031341 or BR031354.

The problem was discovered by FSIS sampling collected during routine reinspection. The sampled product was held, but further investigation by Santa Maria Foods revealed that additional potentially implicated product had been released into commerce. FSIS and the company have received no reports of illnesses associated with consumption of these products. Anyone concerned about an illness should contact a healthcare provider.

Listeria: Why so deadly to the Elderly and Pregnant Women

Food Poisoning Bulletin – Full Article at this link.

Listeria is the common name for the pathogenic or disease-causing bacterium known as Listeria monocytogenes.  It is a foodborne bacterium that, when ingested, causes an infection known as listeriosis.[1]  Approximately 2,500 illnesses and 500 deaths are attributed to listeriosis in the United States annually.[2]

Listeria is ubiquitous in the environment, and can be isolated from wild and domestic animals, birds, insects, soil, wastewater, and vegetation.  The bacterium easily comes into contact with farm animals, as it has been found to be present in grazing areas, stale water, and poorly prepared animal feed.  In addition to being present in the environment, Listeria can live in the intestines of humans, animals, and birds for long periods of time without causing infection.

USA – Research – What is Salmonella

Food Poisoning BulletinSalmonella

It has long been said that, in 1885, pioneering American veterinary scientist, Daniel E. Salmon, discovered the first strain of Salmonella.  Actually, Theobald Smith, research-assistant to Dr. Salmon, discovered the first strain of Salmonella–Salmonella cholerae suis.  But, being the one in charge, Dr. Salmon got all the credit.  In any case, today the number of known strains of the bacteria totals over two thousand.  In recent years, concerns have been raised, as particular strains of the bacteria have become resistant to traditional antibiotics, in both animals and humans.

USA – Research -The E. coli O157:H7 Bacteria and its Complications

Food Poisoning BulletinEcoli Istock

E. coli O157:H7 is one of hundreds of strains of the bacterium Escherichia coli.[1]  Most strains of E. coli are harmless and live as normal flora in the intestines of healthy humans and animals.[2]  The E. coli bacterium is among the most extensively studied microorganism.[3]  The combination of letters and numbers in the name of the E. coli O157:H7 refers to the specific markers found on its surface and distinguishes it from other types of E. coli.[4]  The testing done to distinguish E. coli O157:H7 from its other E. coli counterparts is called serotyping.[5]  Pulsed-field gel electrophoresis (“PFGE”),[6]sometimes also referred to as genetic fingerprinting, is used to compare E. coli O157:H7 isolates to determine if the strains are distinguishable.[7]

USA – USDA Salmonella Reduction Stratergy

FDA FSISUSDA

The U.S. Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS) today released its Salmonella Action Plan that outlines the steps it will take to address the most pressing problem it faces–Salmonella in meat and poultry products. An estimated 1.3 million illnesses can be attributed to Salmonella every year.

“Far too many Americans are sickened by Salmonella every year. The aggressive and comprehensive steps detailed in the Salmonella Action Plan will protect consumers by making meat and poultry products safer.” said Under Secretary for Food Safety Elisabeth Hagen.

The Salmonella Action Plan is the agency’s strategy to best address the threat of Salmonella in meat and poultry products.  The plan identifies modernizing the outdated poultry slaughter inspection system as a top priority. By focusing inspectors’ duties solely on food safety, at least 5,000 illnesses can be prevented each year.

 

USA – CDC New Tool For Food Safety in Restaurants

Food Poisoning BulletinE.coli O157

Almost half of all foodborne illness outbreaks that occur every year in the U.S. are associated with restaurants and delis. The CDC has released new findings and prevention tools to improve food safety in restaurants. Public health officials say that increased awareness and implementation of proper food safety in restaurants and delis may prevent many of the foodborne illness outbreaks reported every year in the U.S.

Education of restaurant workers and public health surveillance are two critical tools necessary in preventing these illnesses. Food preparation and handling practices, worker health policies, and hand-washing practices are some of the factors that are not reported during outbreaks. Carol Selman, head of the CDC’s Environmental Health Specialists Network team said, “inspectors have not had a formal system to capture and report the underlying factors that likely contribute to foodborne outbreaks or a way to inform prevention strategies and implement routine corrective measures to prevent future outbreaks.”

USA – Vibrio Outbreak Raw Oysters

Food Poisoning BulletinVibrio

Vibrio outbreak associated with eating raw oysters and raw clams has sickened at least 104 people in 13 states over the last six months, according to the Centers for Disease Control and Prevention (CDC). Six people have been hospitalized.

Public health investigators have traced the source of some of these illnesses to shellfish harvest areas in Connecticut, Massachusetts, New York, and Virginia. Massachusetts issued a recall of oysters,  Connecticut issued a recall of oysters and clams. Implicated harvest areas in Virginia were closed in July and remain closed.  In Massachusetts, they were closed in August and remain closed. In New York they were closed in June and reopened in mid-September. In Connecticut, they were closed in August and reopened in mid-September.
