Ground beef recalled for Listeria contamination

The USDA announced Tuesday that ground beef patties distributed to schools had been recalled for contamination with Listeria monocytogenes.  According to the USDA recall announcement:

hamburgerThe Maramont Corporation, a Brooklyn, N.Y, firm, is voluntarily recalling approximately 88 pounds of a beef patty product that may be contaminated with Listeria monocytogenes, the U.S. Department of Agriculture's Food Safety and Inspection Service announced today.

The following product is subject to recall:

* 2-oz packages of "BROILED BEEF PATTY (MICROWAVE)." The products were individually packaged and delivered from 17.25-pound cases. Each case label bears a lot code of "07352" and product number "2801." Each case label also bears the establishment number "EST. 5370" inside the USDA mark of inspection.

The beef patty products were produced on Dec. 18 and distributed on Dec. 19 to schools in the Jersey City, N.J., area.

It is believed that ingestion of as few as 1,000 cells of Listeria bacteria can result in illness. After ingestion of food contaminated with Listeria, incubation periods for infection are in the range of 3 to 70 days, usually 4 to 21 days.

Five days to three weeks after ingestion, Listeria has access to all body areas and may involve the central nervous system, heart, eyes, or other locations. Fetuses of pregnant women are particularly vulnerable to the Listeria bacterium. A person with listeriosis usually has fever, muscle aches, and gastrointestinal symptoms such as nausea or diarrhea. If infection spreads to the nervous system, symptoms such as headache, stiff neck, loss of balance, confusion, obtundation or convulsions can occur. With brain involvement, listeriosis may mimic a stroke.

Infected pregnant women ordinarily experience only a mild, flu-like illness; however, infection during pregnancy can lead to miscarriage, infection of the newborn, or even stillbirth. The perinatal and neonatal mortality rate is 80%.

Human cases of Listeria are, for the most part, sporadic and treatable. Nonetheless, Listeria remains an important threat to public health, especially among those most susceptible to this disease. With the increase of the numbers of immunocompromised people, the risk multiplies. The fact that Listeria is a disease easily transmitted from mother to fetus through the placenta is worrisome to an expectant mother, especially since pregnant women themselves rarely show outward signs of such a devastating infection.

North Carolina: Listeriosis results in stillbirths, premature birth

North Carolina health officials announced that at least three pregnant women recently suffered the effects of listeriosis, the illness caused by the ingestion of Listeria monocytogenes - a foodborne pathogen

The News & Observer reported on the listeriosis cases, which at this point are reportedly not related.

Two North Carolina women, including one in Durham County, suffered stillbirths and a third delivered prematurely after consuming foods tainted with the bacterium Listeria monocytogenes, state public health officials said today.

The three cases, which included a stillbirth in Mecklenberg County and a premature birth in Moore County, are considered unrelated, according to the N.C. Division of Public Health.

The infections are thought to be linked to soft, unpasteurized cheeses popular in Hispanic cuisine. All three women are Hispanic.

Another pregnant woman in Buncombe County lost her baby to what public health officials suspect is a fourth case of listeriosis. The ethnicity of that woman is unknown.

Listeria monocytogenes - a serious foodborne pathogen

The Times-Argus of Barre and Montpelier, Vermont, featured an article about Listeria monocytogenes, a foodborne pathogen.  The article focuses on the need for specific populations (i.e. pregnant women, elderly people) to be aware of the risks Listeria poses to them, and on the importance of public knowledge about Listeria since it is present in many environments and can be a contaminant in processed foods.

Listeria emerged as a serious contamination problem in meat and poultry products in the 1980s. By 1999, an especially virulent strain of L. monocytogenes had evolved, alarming health officials and prompting them to urge food producers to clean up their act. When another disastrous outbreak occurred in 2002, the inspection service concluded that voluntary measures were not enough and more stringent regulations were needed.

Although the "interim final rule" for ready-to-eat meat and poultry products issued in 2003 has helped control exposure to the bacteria, it has clearly not eliminated it. According to the Centers for Disease Control and Prevention, an estimated 2,500 people become seriously ill with listeriosis each year, and 500 people die of it.

Last year, in a further effort to protect the public, the Food and Drug Administration approved using an antiseptic spray to help control contamination of ready-to-eat meat and poultry products. The spray contains a mix of six bacteriophages, otherwise harmless viruses that destroy L. monocytogenes. Consumers cannot tell, however, whether this spray has been used, which means those at risk of serious listeria infections should continue to follow the guidelines below.

Listeria found in lettuce

Listeria monocytogenes, a potentially deadly foodborne pathogen, has been found in lettuce samples, according to a story published at monstersandcritics.com

WKMG-TV in Orlando reported Saturday that Listeria bacteria has been linked to lettuce imported from California and sold at a Fresh Market store. Store officials said late Friday the lettuce has been pulled and no reports of illness had been made.

"We will continue to monitor the situation to ensure our stores are taking all necessary precautions," Fresh Market said in a press statement.

Listeria monocytogenes (Listeria) is a pathogenic (disease-causing) bacterium that is food borne and causes an illness called listeriosis. It is frequently overlooked as a possible cause of illness due to its unique growth capabilities. First, it is somewhat difficult for laboratories to grow, and when they do so, Listeria can be confused with common harmless contaminants and disregarded. Second, most bacteria grow poorly when temperatures fall below 40°F, while Listeria survives in temperatures from below freezing (20°F) to body temperature and it grows best at 0°F to 50°F, including the temperature range that we use for refrigeration. As a result, Listeria may be transmitted in ready-to-eat foods that have been kept properly refrigerated. Its ability to grow in such diverse environments is just one of the many challenges presented by this dangerous bacterium.

It is estimated that Listeria causes approximately 1,600 cases of listeriosis annually, resulting in 415 deaths.

Listeriosis is the disease caused by Listeria monocytogenes. It is acquired by the ingestion of contaminated foods. Certain groups of individuals are at great risk for listeriosis. These are pregnant women (and their unborn children) and immunocompromised persons (e.g., transplant recipients). Among infants, listeriosis occurs when the infection is transmitted from the mother, either through the placenta or during the birthing process. These host factors, along with the amount of bacteria ingested and the virulence of the strain, determine the risk of disease.

Listeria can invade the body through a normal and intact gastrointestinal tract. Once in the body Listeria bacteria can travel through the blood stream, but are often found inside cells (they are "intracellular" pathogens). Listeria can co-opt the cell's machinery to its own advantage by manipulating the host cell genes, and then move directly from cell-to-cell, avoiding many of the host's defense mechanisms. The bacteria also produce toxins that damages cells.

For unknown reasons, in immune-deficient hosts Listeria invades and grows best in the central nervous system, causing meningitis and/or encephalitis (brain infection). In pregnant women, the fetus is most heavily infected, leading to spontaneous abortion, stillbirths, or sepsis in infancy.

Listeria warning for raw cream

The Food and Drug Administration issued a warning to consumers not to consume Organic Pastures raw cream after testing revealed the product may be contaminated with Listeria monocytogenes, a bacterium that can cause food poisoning.  The FDA stated in its warning:

This product, marketed by Organic Pastures Dairy Company ("Organic Pastures"), Fresno, Calif., may be contaminated with Listeria monocytogenes, an organism which can cause a serious and sometimes fatal disease called Listeriosis in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeriosis can cause miscarriages and stillbirths among pregnant women.

The product was sold in retail stores throughout California and was also available worldwide via phone orders, and is not pasteurized. Pasteurization, a process that heats milk to a specific temperature for a set period of time, kills bacteria responsible for diseases such as listeriosis, salmonellosis, campylobacteriosis, typhoid fever, tuberculosis, diphtheria and brucellosisis. The California Department of Food and Agriculture issued an order to Organic Pastures on September 7 to withdraw the raw cream from retail distribution after routine product sampling at the facility detected the bacteria. As of September 20, 2007, the California Department of Agriculture has now permitted Organic Pastures to sell and distribute raw cream within the state of California.

FDA advises consumers to throw away product labeled as "ORGANIC PASTURES Grade A RAW CREAM" with code dates "SEP 14" through "SEP 21".

Cheese recalled for Listeria contamination

According to the Atlanta Journal-Constitution, Georgia health officials discovered Listeria monocytogenes in a sample of Italian-made Ricotta Salata cheese.  Listeria causes an illness known as listeriosis, which can be particularly severe in pregnant women and elderly people.  The AJC reported:

The agriculture department said the contamination was found in a package imported under the brand name of Locatelli and marked to sell by Jan. 21. The cheese was imported by The Ambriola Company, Inc. of Jersey City, New Jersey.

Sandwiches recalled for possible Listeria contamination

Cloud's Food Service is recalling tuna salad and egg salad sandwiches for possible contamination with Listeria Monocytogenes, a foodborne bacterium.  4219 units are included in the recall, according to the Food and Drug Administration, which posted a recall notice on its webste:

These sandwiches are labeled with "Cloud's Tuna Salad" and "Cloud's Egg Salad" located on the product label. The product was packaged in flexible plastic film and plastic wedges. Recalled products are as follows:

* Cloud's Tuna Salad Sandwich on White Bread, 5 oz., date code 62607-72507
* Cloud's Egg Salad Sandwich on White Bread, 5 oz., date code 41907-72507

All sandwiches were sold in convenience stores in East Texas, West Louisiana and Southwest Arkansas.

Listeria warning for raw milk in Pennsylvania

Pennsylvania health authorities have issued a warning to consumers who purchased raw milk from a dairy.  The raw milk may be contamianted with Listeria monocytogenes, a foodborne pathogen.  According to a story on the Solanco News Web site:

"During routine inspection, a preliminary test showed the presence of Listeria bacteria in some of the raw milk samples taken from the Misty Mountain dairy," said [Agriculture Secretary Dennis] Wolff. "If consumers have raw milk from this farm, they should discard it immediately."

There have been no illnesses reported because of the potential contamination, but if individuals who consumed the raw milk become ill, they are advised to consult their physician. Raw milk is milk that has not been pasteurized or homogenized.
