Scientific Breakthrough Prevents E. coli From Surviving In Cattle

In the continuing battle to prevent naturally occurring microorganisms like E. coli O157:H7 from growing in cattle, researchers have discovered some promising new tools.

Although E. coli O157:H7 can cause illness in humans, the bacteria often exists as part of the gastrointestinal flora in healthy cattle. In turn, microbiologists at the University of Texas (“UT”), Southwestern Medical Center, working with the USDA, uncovered a mechanism which actually prevents E. coli O157:H7 from surviving in grain-fed cattle.

E. coli O157:H7 harbors a gene called sdiA, which makes the SdiA protein. When traveling within a cattle’s body, the SdiA protein senses a chemical made by microbes in the animal's rumen, the first of a cow's four stomachs, which serves as a large fermentation chamber.

Only after detecting this signal will the bacteria pass through the rumen and colonize in the recto-anal junction. By interfering with the SdiA protein (or, the genetic sensor), however, researchers were able to stop the bacteria from ever reaching the required colonization site. Notably, rather than colonizing, the bacteria simply died off, preventing any potential for future shedding or contamination.

"We're diminishing colonization by not letting pathogen go where it needs to go," said Dr. Vanessa Sperandio, associate professor of microbiology and biochemistry at UT Southwestern and senior author of the study. "If we can find a way to prevent these bacteria from ever colonizing in cattle, it's possible that we can have a real impact on human disease.” Notably, “[t]his could be something as simple as including some sort of antagonist in cattle feed, which would result in less shedding of the bacteria and less contamination down the road."

The findings, of course, are important because an estimated 70 percent to 80 percent of cattle herds can carry these pathogens. According to Dr. Sperandio, the finding “serves as a proof-of-principle that we might be able to target this system and help prevent food contamination."

Salmonella Concerns Prompt Hazelnut Recall

According to the FDA, Willamette Shelling has announced a recall of 114,350 pounds of shelled hazelnuts. To date, additional companies affected by the recall include Willamette Filbert Growers, Kunze Farms, and numerous other distributors and grocers nationwide.

The Willamette Shelling hazelnuts subject to the recall were shelled at a facility (located in Newberg, Oregon) for distribution to numerous down-stream hazelnut processors. Specifically, shelled hazelnuts distributed by the company were sent to various Oregon processors, along with a Canadian processor, and then further distributed by those firms.

All products subject to the initial Willamette Shelling recall were packed in 25 and 50 pound corrugated boxes, and marked with lot code numbers 296091A, 299091A, 300091A, VH3696BO, and 310091A. The corrugated boxes were also marked with the following brand names: Kunze Farms, Evonuk Oregon Hazelnuts, Canadian Hazelnuts, and Firestone Farms. It is important to note, however, that Willamette Shelling unshelled hazelnuts are not affected by this recall. Click on the following link to view a copy of the FDA Recall Releas (Willamette Shelling).

Willamette Shelling announced the recall immediately after learning that routine, random sampling confirmed positive for Salmonella in one of its hazelnut production lots. In turn, in an abundance of caution, and to ensure consumer safety, the company elected to voluntarily recall all shelled hazelnuts processed at its facility between October 12, 2009 and November 25, 2009. Thus, any hazelnut processors who used potentially recalled product are urged to return the product directly to Willamette Shelling.

As noted, the additional following downstream companies affected by the recall included Willamette Filbert Growers (of Newberg, Oregon), Kunze Farms (of Dayton, Oregon), and additional distributors and grocers located in Colorado:

  • Contemporaneous with the announcement of the original recall, Willamette Filbert Growers announced its own recall of 29,861 pounds of potentially affected Shelled Hazelnuts and Shelled Organic Hazelnuts. The Willamette Filbert products subject to the recall were packed in 25 pound corrugated boxes, labeled with “Willamette Filbert Growers” or “Meridian Organic Hazelnuts,” and lot code numbers 289091A and 311091A. The hazelnuts were distributed in Oregon and California through wholesale distributors and for direct delivery. Here too, unshelled hazelnuts are not subject to the recall. Click on the following link to view a copy of the FDA Recall Release (Willamette Filbert).

Any customers who may have purchased Willamette Filbert Shelled Hazelnuts or Meridian Organic Hazelnuts are being urged by the company to return the product to the place of purchase for a full refund. Consumers with questions may contact Ben Mitchell at (503) 538-9256.

  • Following the original recall announcement by Willamette, Kunze Farms also announced its own recall of 32,950 pounds of potentially affected hazelnut kernels. The Kunze Farms product was packed in 25 pound cartons, under the product brand name of Kunze Farms, ‘Select Shelled Hazelnuts’ Dayton, Oregon, with the code numbers 289091A or 299091A. The hazelnut kernels were distributed to several different processors and wholesaler’s in the following areas: Dayton, Oregon; Milton-Freewater, Oregon; Hauppauge, New York; Mesa, Arizona; Cottonwood, Arizona; Seattle, Washington; Ogden, Utah; San Antonio, Texas.; and Parker, Colorado. Click on the following link to view a copy of the FDA Recall Release (Kunze Farms).

In turn, consumers who may have purchased Kunze hazelnuts affected by the recall are being urged by the company to return the products to the place of purchase for a full refund. Consumers with questions may contact Kurt Kunze at (503) 864-2102.

The Colorado Department of Public Health has also identified additional companies that have been affected by the recall. Click on the following link to view the CDPH Hazelnut Recall Notice.

In Colorado, the recalled hazelnuts were sold by Mountain Man Nuts and Fruits Co. via the Internet, to numerous stores and sales distributors. Additionally, the product was distributed in Colorado to a variety of retail firms for bulk sale, including Whole Food Markets, Ft. Collins Food Co-op, Mountain Mama Natural Foods in Colorado Springs, and Healthy Solutions, in Denver.

All firms receiving recalled product have reportedly been notified, and the product is being pulled from shelves. Currently, the following additional products and lot codes are being recalled:

According to the CDPH, products with these lot codes may also have been used as a component in certian gift baskets, including the 12 Tastes Basket, Bounty Basket and Half-Pound Sample Baskets. Moreover, given the potentially wide distribution of recalled product, additional recalls will likely be announced.

DECEMBER 23, 2009 UPDATE:

In addition to the specific recalls identified above, additional downstream companies have announced or expanded recalls of potentially affected products.  These include the following:

Finally, it is important to note that, to date, there have been no reports of illnesses associated with the consumption of these products. Nevertheless, Willamette has ceased production and is working closely with FDA to investigate the issue, and will resume production and shipment  when any potential concerns have been resolved.

Possible Salmonella Concerns Prompt Voluntary And Precautionary Watermelon Recall

According to the FDA, Timco Worldwide Inc. (based in Davis, California) has announced a voluntary recall of a limited number of Large Seedless Watermelons.

The Large Seedless Watermelons affected by the precautionary recall contain the “MelonUp!” sticker label, with a PLU (Price Look Up) # 4032 and UPC # 0 33383 40240 6. The watermelons were distributed to select grocers, wholesalers and processors in California and Texas. Click on the following link to view a copy of the FDA Recall Release.

Timco announced the recall immediately after learning that routine, random sampling by a distribution company confirmed positive for Salmonella. In turn, the company announced, in an abundance of caution, a recall of all potentially affected products.

It is also important to note that, to date, there are no reports of illnesses associated with the consumption of these products. Nevertheless, consumers who may have purchased watermelons in the markets noted above (with the MelonUp! label) are being urged by the company to return them to the place of purchase for a refund.

New Rules May Allow State-Inspected Meat And Poultry To Be Shipped Over State Lines

The USDA has published new rules for a proposed program, under which select State-inspected establishments (with 25 or fewer employees) will be eligible to ship meat and poultry products in interstate commerce. Click on the following link to view the Proposed Rule.

The new program was created as part of the 2008 Farm Bill to supplement the existing Federal-State cooperative inspection program to allow State-inspected plants with 25 or fewer employees to ship products across State lines. This announcement is part of the USDA's new Know Your Farmer, Know Your Food Initiative, which seeks to better connect consumers with local producers to help develop local and regional food systems to spur economic opportunity.

"This new cooperative interstate shipment program will provide new economic opportunities for many small and very small meat and poultry establishments, whose markets are currently limited," said USDA Deputy Under Secretary for Food Safety Jerold Mande. "We can provide new markets for these establishments, while maintaining the integrity of the Federal mark of inspection."

Currently, 27 states operate State Inspection Programs for meat and poultry, and FSIS verifies that the State programs are implementing requirements that are "at least equal to" those imposed under the Federal meat and poultry products inspection acts. Click on the following link to view the Current List of Qualifying States. For these programs, FSIS provides up to 50 percent of the State's operating funds and provides oversight and enforcement of the program.

Under the proposed rule, selected establishments will receive inspection services from federally trained and/or supervised State inspection personnel who will verify that the establishments meet all Federal food safety requirements. Meat and poultry products produced under the voluntary cooperative program will bear an official USDA mark of inspection, thereby enabling interstate shipment of the products.

State-inspected establishments that are not selected for the voluntary cooperative program, including state-inspected establishments with more than 25 employees, are only eligible to sell and ship their products within their State.

Comments must be received on or before Monday, November 16, 2009, through the Federal eRulemaking Portal at www.regulations.gov, by mail to: FSIS Docket Room, USDA, FSIS, OPPD, Docket Clearance Unit, 5601 Sunnyside Avenue, Stop 5272, Beltsville, MD 20705.

All comments must identify FSIS and the docket number FSIS-2008-0039. Once received and published, interested parties will be able to View All Comments Online.

Salmonella Concerns Prompt Parsley Recall

According to the FDA, Muranaka Farms has announced a voluntary recall of 1005 cases of 60 count bunched Parsley because it has the potential to be contaminated with Salmonella.

The recall was trigged as a result of a voluntary sampling program conducted by the California company in cooperation with the FDA, which revealed that certain finished products could potentially contain the bacteria. Click on the following link to view the FDA Recall Release.

The specific products affected by the recall include 60 count fresh bunched parsley Lot Code 0023909. The products were shipped in a brown wax carton under the Muranaka Label with a parsley silhouette on the side. In turn, individual parsley bunches were banded using a red rubber band. The lot code 0023909 is on a sticker on the outside of the carton.

The affected products were distributed in the following 10 states: Arizona (30 cases), California (574 cases), Colorado (35 cases), Florida (60 Cases), Iowa (3 cases), Illinois (1 case), Missouri (7 cases), Tennessee (5 cases), Texas (278 cases) and Wisconsin (12 cases). These cases were distributed within both retail and foodservice outlets.

Because of Muranaka Farm's trace recall program the company was able to immediately determine which customers purchased the product in question. Muranaka's food safety protocols also ensure the company was able to determine the amount of cases harvested, the crew harvesting the product, and the field on which the parsley was grown and harvested. The company is continuing to work with the FDA to determine a potential cause.

It is also important to note that, to date, there have been no reported illnesses associated with the consumption of these products. Moreover, although the product is over two weeks old, and likely past its useable shelf-life, the company is nevertheless working diligently with customers to ensure that the products are fully accounted for and out of the supply chain.

Salmonella Testing Prompts Nationwide Lettuce Recall

Tanimura & Antle (located in Salinas, California) has announced a voluntary recall of various romaine lettuce products following a finding of Salmonella in a random sampe taken by the Wisconsin Department of Agriculture. Immediately after being informed of the positive test result, the company initiated comprehensive trace-back efforts, and was able to contact all customers within hours. Those buyers have been told to destroy the lettuce.

The recalled lettuce, which had been distributed to retail, foodservice and wholesale customers in 29 states, was harvested between June 25 and July 2, 2009. The specific products affected by the recall include cartons of bulk and wrapped lettuce with a lot code 531380. Click here to view a copy of the Company Press Release.

According to Tanimura & Antle, the affected products were distributed to the following states: Alabama, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Massachusetts, Michigan, Missouri, Nebraska, New Hampshire, New Mexico, Nevada, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Texas, Utah, Virginia, Wisconsin and Wyoming.

Chief executive officer Rick Antle stated that Tanimura & Antle practices strict food safety guidelines. Additionally, despite the lettuce being past its shelf life, he cited an "abundance of caution" in issuing the recall. "We will continue to review opportunities for improvement," Antle said. “Although the recalled product is well beyond the 14-16 day shelf life, we are voluntarily issuing this recall because we want to ensure that we minimize even the slightest risk to public health.”

To date, there have been no reports of illness associated with the lettuce. Moving forward, the company also stated that it will continue to update its website with more information. Consumers with questions, or who need information, may call Tanimura & Antle at 1-877-827-7388.

AUGUST 3, 2009 UPDATE:

On August 3, 2009, Tanimura & Antle expanded the geographic scope of its original recall to include product distributed to all 50 states.  Although the volume of cases from the single recalled lot (which is identified above) has not changed, the company recognizesd the possibility that some customers may have distributed the romaine in states beyond the original 29 -- thus, prompting the expansion.
