WASHINGTON, Nov. 9, 2012 – Black Earth Meat Market Inc., a Black Earth,
Wis. establishment, is recalling approximately 99 pounds of beef tongue products
because they may not have had the tonsils completely removed, which is not
compliant with regulations that require the removal of tonsils from cattle of
all ages, the U.S. Department of Agriculture's Food Safety and Inspection
Service (FSIS) announced today.
The products subject to recall are: [View Labels (PDF Only)]
Various size cases of Black Earth Meats Natural Beef Tongues and Black
Earth Meats Local Beef Tongues produced on October 8, 11, 17 and 18, 2012.
The products bear Est. 34379 inside the USDA mark of inspection and were
distributed to a restaurant in Wisconsin and a distributor in Illinois.
The problem was discovered during a routine Food Safety Assessment at the
establishment. Tonsils are considered a specified risk material (SRM) and must
be removed from cattle of all ages in accordance with FSIS regulations. SRMs are
tissues that are known to contain the infective agent in cattle infected with
Bovine Spongiform Encephalopathy (BSE), as well as materials that are closely
associated with these potentially infective tissues. Therefore, FSIS prohibits
SRMs from use as human food to minimize potential human exposure to the BSE
agent. There is no indication that any of the cattle slaughtered displayed any
signs of BSE.
FSIS routinely conducts recall effectiveness checks to verify recalling
firms notify their customers of the recall and that steps are taken to make
certain that the product is no longer available to consumers.
Consumers and media with questions about the recall should contact Bartlett
Durand, Managing Member, at (608)767-3940.
Consumers with food safety questions can "Ask Karen," the FSIS virtual
representative available 24 hours a day at AskKaren.gov or via smartphone at
m.askkaren.gov. "Ask Karen" live chat services are available Monday through
Friday from 10 a.m. to 4 p.m. ET. The toll-free USDA Meat and Poultry Hotline
1-888-MPHotline (1-888-674-6854) is available in English and Spanish and can be
reached from l0 a.m. to 4 p.m. (Eastern Time) Monday through Friday. Recorded
food safety messages are available 24 hours a day. #

The present study demonstrated successful intraspecies transmission of

in the brain of the H-type BSE-challenged cattle. TSE agent virulence can be
minimally defined by oral transmission of different TSE agents (C-type, L-type,
and H-type BSE agents) [59]. Oral transmission studies with H-type BSEinfected
cattle have been initiated and are underway to provide information regarding the
extent of similarity in the immunohistochemical and molecular features before
and after transmission.
In addition, the present data will support risk assessments in some
peripheral tissues derived from cattle affected with H-type BSE.

Clinical and Pathologic Features of H-Type Bovine Spongiform Encephalopathy
Associated with E211K Prion Protein Polymorphism

Abstract
The majority of bovine spongiform encephalopathy (BSE) cases have been
ascribed to the classical form of the disease. Htype and L-type BSE cases have
atypical molecular profiles compared to classical BSE and are thought to arise
spontaneously. However, one case of H-type BSE was associated with a heritable
E211K mutation in the prion protein gene. The purpose of this study was to
describe transmission of this unique isolate of H-type BSE when inoculated into
a calf of the same genotype by the intracranial route. Electroretinograms were
used to demonstrate preclinical deficits in retinal function, and optical
coherence tomography was used to demonstrate an antemortem decrease in retinal
thickness. The calf rapidly progressed to clinical disease (9.4 months) and was
necropsied. Widespread distribution of abnormal prion protein was demonstrated
within neural tissues by western blot and immunohistochemistry. While this
isolate is categorized as BSE-H due to a higher molecular mass of the
unglycosylated PrPSc isoform, a strong labeling of all 3 PrPSc bands with
monoclonal antibodies 6H4 and P4, and a second unglycosylated band at
approximately 14 kDa when developed with antibodies that bind in the C-terminal
region, it is unique from other described cases of BSE-H because of an
additional band 23 kDa demonstrated on western blots of the cerebellum. This
work demonstrates that this isolate is transmissible, has a BSE-H phenotype when
transmitted to cattle with the K211 polymorphism, and has molecular features
that distinguish it from other cases of BSE-H described in the literature.
snip...
Most significantly it must be determined if the molecular phenotype of this
cattle TSE remains stable when transmitted to cattle without the E211K
polymorphism as several other isolates of atypical BSE have been shown to adopt
a molecular profile consistent with classical BSE after passage in transgenic
mice expressing bovine PrPC [40] or multiple passages in wild type mice [23].
Results of ongoing studies, namely passage of the E211K Htype isolate into
wild-type cattle, will lend further insight into what role, if any, genetic and
sporadic forms of BSE may have played in the origins of classical BSE. Atypical
cases presumably of spontaneous or, in the case of E211K BSE-H, genetic origins
highlight that it may not be possible to eradicate BSE entirely and that it
would be hazardous to remove disease control measures such as prohibiting the
feeding of meat and bone meal to ruminants.

Disease Center), USA
Background: Classical BSE is a world-wide prion disease in cattle, and the
classical BSE strain (BSE-C) has led to over 200 cases of clinical human
infection (variant CJD). Atypical BSE cases have been discovered in three
continents since 2004; they include the L-type (also named BASE), the H-type,
and the first reported case of naturally occurring BSE with mutated bovine PRNP
(termed BSE-M). The public health risks posed by atypical BSE were largely
undefined.
Objectives: To investigate these atypical BSE types in terms of their
transmissibility and phenotypes in humanized mice. Methods: Transgenic mice
expressing human PrP were inoculated with several classical (C-type) and
atypical (L-, H-, or Mtype) BSE isolates, and the transmission rate, incubation
time, characteristics and distribution of PrPSc, symptoms, and histopathology
were or will be examined and compared.
Results: Sixty percent of BASE-inoculated humanized mice became infected
with minimal spongiosis and an average incubation time of 20-22 months, whereas
only one of the C-type BSE-inoculated mice developed prion disease after more
than 2 years. Protease-resistant PrPSc in BASE-infected humanized Tg mouse
brains was biochemically different from bovine BASE or sCJD. PrPSc was also
detected in the spleen of 22% of BASE-infected humanized mice, but not in those
infected with sCJD. Secondary transmission of BASE in the humanized mice led to
a small reduction in incubation time.*** The atypical BSE-H strain is also
transmissible with distinct phenotypes in the humanized mice, but no BSE-M
transmission has been observed so far.
Discussion: Our results demonstrate that BASE is more virulent than
classical BSE, has a lymphotropic phenotype, and displays a modest transmission
barrier in our humanized mice. BSE-H is also transmissible in our humanized Tg
mice. The possibility of more than two atypical BSE strains will be discussed.

Classical BSE is a world-wide prion disease in cattle, and the classical
BSE strain (BSE-C) has led to over 200 cases of clinical human infection
(variant CJD). Two atypical BSE strains, BSE-L (also named BASE) and BSE-H, have
been discovered in three continents since 2004. The first case of naturally
occurring BSE with mutated bovine PrP gene (termed BSE-M) was also found in 2006
in the USA. The transmissibility and phenotypes of these atypical BSE
strains/isolates in humans were unknown. We have inoculated humanized transgenic
mice with classical and atypical BSE strains (BSE-C, BSE-L, BSE-H) and the BSE-M
isolate. We have found that the atypical BSE-L strain is much more virulent than
the classical BSE-C.*** The atypical BSE-H strain is also transmissible in the
humanized transgenic mice with distinct phenotype, but no transmission has been
observed for the BSE-M isolate so far.
