What is the risk of chronic wasting disease being introduced into Great Britain? An updated Qualitative Risk Assessment March 2016
Sheep and cattle may be exposed to CWD via common grazing areas with affected deer but so far, appear to be poorly susceptible to mule deer CWD (Sigurdson, 2008).
***In contrast, cattle are highly susceptible to white-tailed deer CWD and mule deer CWD in experimental conditions but no natural CWD infections in cattle have been reported (Sigurdson, 2008; Hamir et al., 2006). It is not known how susceptible humans are to CWD but given that the prion can be present in muscle, it is likely that humans have been exposed to the agent via consumption of venison (Sigurdson, 2008). Initial experimental research, however, suggests that human susceptibility to CWD is low and there may be a robust species barrier for CWD transmission to humans (Sigurdson, 2008). It is apparent, though, that CWD is affecting wild and farmed cervid populations in endemic areas with some deer populations decreasing as a result.
snip...
For the purpose of the qualitative risk assessment developed here it is necessary to estimate the probability that a 30-ml bottle of lure contains urine from an infected deer. This requires an estimate of the proportion of deer herds in the USA which are infected with CWD together with the within herd prevalence.
The distribution map of CWD in US shows it is present mainly in central states (Figure 1). However, Virginia in the east of the country has recorded seven recent cases of CWD (Anon 2015a). Some US manufacturers claim to take steps to prevent urine being taken from infected animals eg by sourcing from farms where the deer are randomly tested for CWD (Anon 2015a). However, if disease is already present and testing is not carried out regularly, captive populations are not necessarily disease free (Strausser 2014). Urine-based deer lures have been known to be collected from domestic white-tailed deer herds and therefore there is a recognised risk. This is reflected by 6 US States which have
14
banned the use of natural deer urine for lures, as the deer urine may be sourced from CWD-endemic areas in the USA as well as from areas free of CWD. For example, the US State of Virginia is banning the use of urine-based deer lures on July 2015 and Vermont from 2016 due to the risk of spread of CWD. Alaska banned their use in 2012 (Anon 2015a). Pennsylvania Game Commission has banned urine-based deer lures and acknowledged that there is no way to detect their use (Strausser 2014). On the basis of unpublished data (J. Manson, Pers. Comm.) it appears that up to 50% of deer herds can be infected with 80-90% of animals infected within some herds.
*** It is therefore assumed that probability that a 30-ml bottle of deer urine lure imported from the USA is sources from an infected deer is medium.
SNIP...
In the USA, under the Food and Drug Administration’s BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. ***For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system. ***However, this recommendation is guidance and not a requirement by law.
***Animals considered at high risk for CWD include:
***1) animals from areas declared to be endemic for CWD and/or to be CWD eradication zones and
***2) deer and elk that at some time during the 60-month period prior to slaughter were in a captive herd that contained a CWD-positive animal.
***Therefore, in the USA, materials from cervids other than CWD positive animals may be used in animal feed and feed ingredients for non-ruminants. The amount of animal PAP that is of deer and/or elk origin imported from the USA to GB cannot be determined, however, as it is not specified in TRACES. It may constitute a small percentage of the very low tonnage of non-fish origin processed animal proteins that were imported from US into GB.
*** Overall, therefore, it is considered there is a greater than negligible risk that (non-ruminant) animal feed and pet food containing deer and/or elk protein is imported into GB. There is uncertainty associated with this estimate given the lack of data on the amount of deer and/or elk protein possibly being imported in these products.
