New York Firm Recalls Beef Carcass That Contains Prohibited Materials (BSE)

New York Firm Recalls Beef Carcass That Contains Prohibited Materials


Congressional and Public Affairs (202) 720-9113 Atiya Khan

WASHINGTON, January 15, 2010 - Jerry Hayes Meats Inc., a Newark Valley, N.Y., establishment is recalling approximately 490 pounds of a beef carcass that may not have had the spinal column removed, which is not compliant with regulations that require the removal of spinal cord and vertebral column from cattle over 30 months of age, the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) announced today.

Spinal cord and vertebral column are considered a specified risk material (SRM) and must be removed from cattle over 30 months of age 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.

The products subject to recall include: 1- "BEEF CARCASS," which bears the establishment number "EST. 04488 M" inside the USDA mark of inspection.

The product was packed on January 7, 2010, and sold to a single customer in New York.

The problem was discovered through routine FSIS inspection activities. FSIS has received no reports of illnesses associated with consumption of this product.

FSIS routinely conducts recall effectiveness checks to verify recalling firms notify their customers (including restaurants) of the recall and that steps are taken to make certain that the product is no longer available to consumers.

Media and consumers with questions about the recall should contact the company's owner, Jerry Hayes at (607) 642-9598.

The most recent assessments (and reassessments) were published in June 2005 (Table I; 18), and included the categorisation of Canada, the USA, and Mexico as GBR III. Although only Canada and the USA have reported cases, the historically open system of trade in North America suggests that it is likely that BSE is present also in Mexico.

Here we go again. This to me is very misleading, why don't they post the rest of the science on TSE and incubation periods ? The FSIS et al know damn good and well that your not going to eat this product and fall over dead immediately or in the next few days, weeks, months from a mad cow type disease i.e. Transmissible Spongiform Encephalopathy. It takes years, decade, and or decades for a TSE to become clinical and kill. Once the TSE is clinical, you better have your things in order, your going to die. ...

Estimation of Epidemic Size and Incubation Time Based on Age Characteristics of vCJD in the United Kingdom Alain-Jacques Valleron,1 Pierre-Yves Boelle,1 Robert Will,2 Jean-Yves Cesbron3

The distribution of the vCJD incubation period that best fits the data within the framework of our model has a mean of 16.7 years, with a standard deviation of 2.6 years. The 95% upper percentile of this distribution is 21.4 years. The 95% confidence interval (CI) of the estimates of the mean and standard deviation is relatively narrow: The 95% CI for the estimate of the mean incubation period is 12.4 to 23.2 years, and the 95% CI of the standard deviation is 0.9 to 8 years (10). The decrease in susceptibility to infection in exposed subjects older than 15 years, as estimated from the parameter , was found to be very sharp: 16% per year of age (CI: 12 to 23%). This means that, under the best fitting hypothesis, an individual aged 20 years in 1981 had 55% less risk of becoming infected than a child aged 15 years (99.9% for an individual aged 70).

Interpretation Incubation periods of infection with human prions can exceed 50 years. In human infection with BSE prions, species-barrier effects, which are characteristic of cross-species transmission, would be expected to further increase the mean and range of incubation periods, compared with recycling of prions within species. These data should inform attempts to model variant CJD epidemiology.

Creutzfeldt-Jakob disease 38 years after diagnostic use of human growth hormone

E A Croes, G Roks, G H Jansen, P C G Nijssen, C M van Duijn ...............................................................

J Neurol Neurosurg Psychiatry 2002;72:792-793

A 47 year old man is described who developed pathology proven Creutzfeldt-Jakob disease (CJD) 38 years after receiving a low dose of human derived growth hormone (hGH) as part of a diagnostic procedure. The patient presented with a cerebellar syndrome, which is compatible with iatrogenic CJD. This is the longest incubation period described so far for iatrogenic CJD. Furthermore, this is the first report of CJD after diagnostic use of hGH. Since the patient was one of the first in the world to receive hGH, other cases of iatrogenic CJD can be expected in the coming years.

Prion diseases are potentially transmissible. Human to human transmission was first reported in 1974, when a 55 year old woman was described who developed symptoms of Creutzfeldt-Jakob disease (CJD) 18 months after a corneal transplant.1 Since then, transmission has been reported after stereotactic electroencephalographic (EEG) depth recording, human growth hormone (hGH) and gonadotrophin treatment, and dura mater transplantation.2-5 More than 267 patients with iatrogenic CJD are known today and their number is growing.6 The most important iatrogenic cause of CJD is still contaminated cadaveric hGH. Exposure to contaminated hGH occurred before 1985, when recombinant growth hormone became available. In a recent study, incubation periods in 139 patients with hGH associated CJD were found to range from 5-30 years, with a median of 12 years.6 One of the factors influencing incubation time is genotype on polymorphic codon 129 of the prion protein gene.7 The incubation time is significantly shorter in people who are homozygous for either methionine or valine on this polymorphism.7

We describe the second patient with hGH related CJD in the Netherlands. The patient developed the disease 38 years after hGH injections. To our knowledge, this is the longest incubation period described for any form of iatrogenic CJD. Further-more, our patient was not treated with hGH but only received a low dose as part of a diagnostic procedure.


This patient presented at the age of 47 years with paraesthesia in both arms for six months, difficulty with walking for four weeks, and involuntary movements of mainly the upper extremities of two weeks' duration. He did not notice any change in cognitive function, although his twin sister had noticed minor memory disturbances. There was no family history of neurological disease. During childhood the patient had experienced a growth delay compared with his twin sister and with the average in the Netherlands. When he was 9 years old, a nitrogen retention test with 6 IU hGH over five days was performed to exclude growth hormone deficiency. Since the result was not decisive, a quantitative amino acid test was performed, which measures 30 amino acids during fasting and one, two, and three hours after growth hormone injection. No abnormal amino acid concentrations were found making the diagnosis of primordial dwarfism most likely. Therefore, no treatment with hGH was given.

On neurological examination we found a slight dysarthria without aphasia. Cranial nerve function was normal. Walking was unstable and wide based. During movements of the upper extremities myoclonic jerks were present. Sensation, muscle tone, and strength were normal. Co-ordination was impaired in all four limbs with a disturbed balance. Tendon reflexes were brisk at the arms and increased at the legs with a clonus in the ankle reflex. Plantar responses were both normal. On the mini mental state examination, the patient scored 30/30. Routine laboratory investigation, thyroid function, vitamin concentrations (B-1, B-6, B-12, and E), and copper metabolism were normal. Admission EEG examination showed generalised arrhythmic slow activity with diffuse spikes and spike waves. EEG examination two months later showed a further slowing of the rhythm with bilateral diphasic sharp waves but was not typical for CJD. Cerebral magnetic resonance imaging was normal. Cerebrospinal fluid examination showed 1 cell/3 µl, normal glucose and protein concentrations, and a strongly positive 14-3-3 protein test. The patient was homozygous for methionine on the PRNP codon 129 polymorphism. On clinical grounds, CJD was diagnosed. Within one month the patient's condition deteriorated rapidly and because of severe disturbances in coordination and progressive myoclonus he became bedridden. An eye movement disorder developed with slow saccadic and dysmetric eye movements. Temperature became unstable with peaks of 39°C without an infectious focus, for which a disorder of autoregulation was presumed. Until a very advanced stage, cognitive function was intact. The patient died five months after admission. The diagnosis of CJD was confirmed at necropsy. The brain weighed 990 g and showed clear cortical and cerebellar atrophy. Spongiosis, neuronal loss, and gliosis were found predominantly in the putamen, caudate nucleus, and basotemporal and cerebellar cortex; the cerebellum was the most severely affected of these. Vacuoles ranged from 2-12 µm. No amyloid or Kuru plaques were found. Immunohistochemical staining (3F4 antibody 1:1000, Senetek, USA) was clearly positive for prion protein accumulation in a "synaptic" distribution. Most deposition was found in the stratum moleculare of the cerebellum.


We describe a 47 year old patient who developed pathology proven CJD 38 years after hGH injections. The patient was never treated with hGH but received a small dose as part of a diagnostic procedure. The onset of CJD was signalled by prodromal symptoms of paraesthesia followed by a rapidly progressive ataxia. The disease presentation and course with predominantly cerebellar and eye movement disorders are compatible with iatrogenic CJD caused by hGH treatment.6 8

Growth hormone treatment was first described in 1958 but hGH was not produced on a larger scale from human pituitary glands until the beginning of the 1960s. In the Netherlands growth hormone extraction started in 1963 and was soon centrally coordinated. Until 1979 growth hormone was extracted non-commercially from pituitaries by a pharmaceutical company. In 1971 commercial products also became available. Our patient was one of the first to receive hGH in the Netherlands but the origin of this product was not recorded. A causal relation can therefore not be established with full certainty, but coincidentally receiving growth hormone and developing this very rare disease is unlikely. Since the clinical course in this relatively young patient is in accordance with an iatrogenic cause, we think the probability is high that the hGH injections explain the development of CJD in this patient.

The first Dutch patient with hGH related CJD died in 1990. 9 During several periods from 1963 to 1969 she received intramuscular injections of hGH. During an unknown period the hGH was derived from South America. At age 39, 27 years after starting the treatment, she developed an ataxic gait, slurred speech, sensory disorders, and myoclonus, but her cognitive function remained normal. Postmortem examination of the brain confirmed the diagnosis of CJD.9 Following the identification of this patient, a retrospective study was started to trace all 564 registered hGH recipients who were treated before May 1985. Until January 1995, none of these was suspected of having CJD.10 Since 1993 prospective surveillance for all forms of human prion disease has been carried out in the Netherlands and, apart from the patient described above, a further two patients with iatrogenic CJD have been identified, who developed the disease after dura mater transplantation.11

An incubation period as long as 38 years had never been reported for iatrogenic CJD. Huillard d'Aignaux et al7 studied the incubation period in 55 patients with hGH related CJD in a cohort of 1361 French hGH recipients. The median incubation period was between 9 and 10 years. Under the most pessimistic model, the upper limit of the 95% confidence interval varied between 17 and 20 years. Although the infecting dose cannot be quantified, it can be speculated that the long incubation period in our patient is partly explained by the administration of a limited amount of hGH. This hypothesis is supported by experimental models, in which higher infecting doses usually produce shorter incubation periods.6 Since our patient was one of the first in the world to receive hGH, this case indicates that still more patients with iatrogenic CJD can be expected in the coming years. Another implication of our study is that CJD can develop even after a low dose of hGH. This case once more testifies that worldwide close monitoring of any form of iatrogenic CJD is mandatory.


We are grateful to M Jansen PhD MD for his search for the origin of the growth hormone and P P Taminiau MD. CJD surveillance in the Netherlands is carried out as part of the EU Concerted Action on the Epidemiology of CJD and the the EU Concerted Action on Neuropathology of CJD, both funded through the BIOMED II programme, and is supported by the Dutch Ministry of Health. This surveillance would not have been possible without the cooperation of all Dutch neurologists and geriatricians. ........................................

Stereotactic multicontact electrodes used to probe the cerebral cortex of a middle aged woman with progressive dementia were previously implicated in the accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger patients. The diagnoses of CJD have been confirmed for all three cases. More than two years after their last use in humans, after three cleanings and repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were implanted in the cortex of a chimpanzee. Eighteen months later the animal became ill with CJD. This finding serves to re-emphasise the potential danger posed by reuse of instruments contaminated with the agents of spongiform encephalopathies, even after scrupulous attempts to clean them.
