My Lords, it is a great pleasure to follow the noble Lord, Lord Lilley, and to join others in congratulating my noble friend Lord Trees on his excellent introduction to this important debate. I also join others in welcoming the Minister and look forward to his maiden speech. I should declare that, among my interests in the register, I am a scientific adviser to Marks & Spencer.
In recent decades, this country has experienced four major farm animal disease outbreaks caused by breaches in biosecurity. First, there was mad cow disease, or BSE, in the 1990s. Here, the deregulation of the manufacture of meat and bone meal and the consequent lapse in biosecurity allowed the disease to spread within the cattle population. The infective agent, the prion protein, could pass on the disease via meat and bone meal because the rendering temperature had been reduced.
Secondly, there was foot and mouth disease in 2001. This epidemic was the result of inadequate biosecurity and monitoring. It originated from infected imported pork products fed as pig swill, and it spread rapidly throughout the country because of movement of livestock. MAFF was slow to recognise the scale of the problem and to implement appropriate biosecurity measures.
The third disease, bovine TB, has been an ongoing problem in this country since the 1980s. Here, there are two biosecurity issues: the transmission from wildlife, primarily badgers, to cattle and transmission from cattle to cattle within and between farms. Although the randomised badger culling trial showed that the latter is more important than the former, in the past 13 years emphasis in policy has been placed on killing badgers rather than on measures to prevent the spread of the disease among cattle. The fact that the comparative skin test for bovine TB in cattle has a sensitivity of only around 50% in field conditions means that there continues to be a hidden reservoir of infection in our cattle population.
The fourth disease caused by problems with biosecurity, referred to by my noble friend Lord Trees, is avian flu. As he said, this poses a particular problem because it is spread by wild migrating birds. What lessons have the Government learned from these four major problems that we have faced in recent times? Have those lessons been enshrined in Defra thinking and in policy for the future?
I will now briefly look to the future. The risks, as my noble friend Lord Trees expressed so clearly in his introduction, include a mixture of unknowns—for
example, mutations of pathogens, just as BSE may have arisen from a mutation of the scrapie agent—and other risk factors that are known and more predictable. We have already heard about these: international trade, wildlife reservoirs, climate change, drug resistance and animal husbandry, as mentioned by the noble Baroness, Lady Bennett of Manor Castle.
I will ask the Minister about two aspects of planning for the future. The first is early warning. The Government have a programme to monitor pathogens called PATH-SAFE, described in their literature as
“a three-year project to develop a pilot national surveillance network, using the latest DNA-sequencing technology and environmental sampling to improve the detection and tracking of foodborne and antimicrobial resistant pathogens through the whole agri-food system from farm to fork”.
Can the Minister update us on the progress of that project?
My second point about the future is import controls, already mentioned by a number of speakers, including the noble Lord, Lord Lilley. As we heard, since Brexit there have been no border checks on imports from the European Union, but the new risk-based approach to inspections, the border target operating model, which has been delayed five times, will finally kick off at the end of this month. It will go through a series of phases in April and October until its introduction is complete. The model relies heavily on documentation rather than physical inspections. What proportion of checks will be physical, rather than looking at pieces of paper? Will port health authorities have the required resources to carry out paper and physical checks?
This applies only to legal imports, and illegal imports are likely to pose much greater risks to biosecurity. We know from the experience of Dover Port Health Authority in October 2022 that there are major consignments of illegal meat coming in from eastern Europe and, importantly, there are still ongoing imports of bush meat from Africa—which is completely unregulated—that could carry major disease risks. What is the Government’s estimate of how much illegal bush meat and other meat is imported into the UK and what is being done to bear down on that and enhance our biosecurity?
