EFSA

Opinion of the BIOHAZ Panel on the assessment of the age limit in cattle
for the removal of certain Specified Risk Materials (SRM).
Last updated: 25 May 2005
(...) If the BSE cases in very young animals are not taken into account
and the mean age at which BSE is detected in the field is taken as the
denominator, then a cut-off at 30 months would represent a considerable
but not an absolute safety margin with respect to detectable BSE
infectivity.

raise the risk of BSE.

cattle trade regarding bovine spongiform encephalopathy -- the
International Animal Health Code Chapter on BSE -- declaring that young

Now that Washington's measures against mad cow disease have come close
to meeting the conditions set by Japan for the resumption of beef
imports from the United States, the Food Safety Commission should
swiftly reach a conclusion on the issue.

Simulation of the options for a national control programme to eradicate
scrapie from Great Britain

Abstract
Because of the risk to public health posed by the potential presence of
bovine spongiform encephalopathy (BSE) in sheep, there are plans to
eradicate transmissible spongiform encephalopathies (TSEs) from the
British sheep population. We used a mathematical model for the spread of
scrapie between sheep flocks to assess the efficacy of five control
strategies at eradicating the infection from the national flock. These
range from ram-genotyping schemes through whole-flock genotyping with
selective culling to whole-flock slaughter. The impact of control was
considered under three scenarios for the long-term dynamics of scrapie
in GB: two in which scrapie is ultimately eliminated (with different
median extinction times) and one in which scrapie remains endemic.
Results suggested that it is feasible to eradicate scrapie from the
British sheep flock, but that any national control programme will take
decades to eliminate the disease and be costly. The most-effective
strategy, measured in terms of the probability of eradication and time
taken for eradication, was predicted to be whole-flock culling, which
was effective under all three scenarios for the long-term dynamics of
scrapie. Strategies involving whole-flock genotyping with selective
culling were also effective, though they were predicted to take longer
to eradicate scrapie than whole-flock culling. Ram-genotyping schemes
were effective in some instances, but not for the scenario where scrapie
remained endemic in the national flock. At low levels of reporting of
clinical disease (<20%) the probability of eradication within 100 years
was predicted to be <100% and, consequently, low levels of reporting
could compromise the effectiveness of a control programme. Moreover, the
predicted time taken to eradicate scrapie would increase markedly if the
reporting compliance decreased.

A quantitative assessment of the BSE risk associated with fly ash and
slag from the incineration of meat-and-bone meal in a gas-fired power
plant in Denmark
Larry G. Paisley , and Julie Hostrup-Pedersen

Danish Institute for Food and Veterinary Research, Mørkhøj Bygade 19,
DK-2860 Søborg, Denmark

Abstract
It has been recommended that meat-and-bone meal (MBM) be incinerated at
850 °C for at least 2 s and the ashes and slag disposed of in controlled
landfills, to dispose of animal-derived proteins. Most commonly, the MBM
is incinerated in cement works or coal-fired power plants and the ashes
and slag are incorporated into the cement or concrete.
Our goal was to assess with a Monte Carlo simulation model the bovine
spongiform encephalopathy (BSE) risk to cattle and humans posed by the
ash and slag. The results will be used by decision makers to evaluate
the need for disposal of the fly ash in controlled landfills and the
feasibility of use of the ash by the phosphate and fertilizer industries.
We assumed that all specified risk material (SRM) and MBM produced in
Denmark would be incinerated in this gas-fired power plant. Based on
observations in 2001, we assumed that, on average, six (range: 0–15)
clinical BSE cases each year were rendered into MBM and incinerated. In
addition, SRM or carcasses from 0 to 31 (median = 10)
BSE-infected-but-undetected animals/BSE case were also incinerated.
The simulations were run on a 1-week basis. Our results suggest that if
the slag is collected and re-incinerated the median BSE infectivity
remaining in the fly ash per week would be 3.1E−11 cattle ID50. A cattle
ID50 is the amount of infectivity that will cause infection in 50% of
cattle exposed to it. During the weeks when BSE was infected in the
SRM-MBM, the median infectivity in the fly ash was estimated as 8.7E−10
cattle ID50 and 2.9E−12 human ID50. The 95th percentiles were 2.1E−08
cattle ID50 and 5.8E−10 human ID50, respectively. One ton of fly ash
would contain ≤1.8E−07 cattle ID50 95% of the time. These are the
potential exposures of the cattle or human populations. The potential
exposures of individuals are far less.
