Biosecurity and Infectious Diseases

Lord Browne of Ladyton Excerpts

Thursday 18th January 2024 Lords Chamber

[Lord Browne of Ladyton (Lab)]

My Lords, it is both a delight and an honour to follow the noble Lord, Lord Rees, and to join other noble Members in congratulating and thanking the noble Lord, Lord Trees, for securing this debate and for his excellent opening speech. We are fortunate in this House to have the benefit of their respective world-class scientific expertise, communication skills and deep commitment to the cause of increasing our biosecurity.

As is now clear, climate change is a driver of multiple other risks, from emerging zoonoses and disease transmission to compromised food security and an increase in drug-resistant infections. The Covid-19 pandemic is a lesson on the degree to which the entire world is vulnerable to a pandemic or another, as yet unanticipated, major public health event. It is sobering that by near-universal consensus, this vulnerability is set only to increase. The IPCC’s Climate Change 2023: Synthesis Report could scarcely be more unequivocal on this specific question. It predicts that, in the near term, we will face

“multiple risks to ecosystems and humans”,

including a greater incidence of

“food-borne, water-borne, and vector-borne diseases”.

These are not merely warnings of a possible dystopian future, but something that already is crystallising into observable reality. We are seeing spikes in malaria transmission in large parts of sub-Saharan Africa, the first ever locally acquired cases of malaria in Florida and Texas, and, as has already been mentioned, outbreaks of dengue fever in Paris. In 2022, there were more cases of dengue fever in Europe than in the entire preceding decade. Forecasts suggest that, owing to a rise in global temperatures, malaria transmission seasons could be up to five months longer by 2070. Malaria rates in Mozambique are at their highest since the current reporting phase began in 2017. Over 70% of anti-malaria drugs in Africa are imported; what are we doing, or encouraging the international community to do, to stimulate local manufacture of drugs to ensure that weaknesses in the international supply chain do not result in preventable deaths in Africa?

What are the Government doing in either conducting or commissioning predictive modelling of the expected impacts of climate change on current and future disease transmission? If we are to equip ourselves adequately to deal with this crisis, a reactive approach will be insufficient. I welcome the new US-UK Strategic Dialogue on Biological Security and would be grateful for an explanation how, in granular terms, such co-operation will enhance our ability to anticipate future biosecurity threats.

On globalisation, I turn now to recent representations to the Government by port health officials in Dover. Since September 2022, when checks were first introduced, 57 tonnes of illegal, non-compliant pork imports have been seized in Dover alone. The Dover port health manager describes the scale of these illegal imports as “unprecedented” and suggests that for every tonne seized, multiple tonnes are going undetected. These illegal pork imports significantly increase the risk of African swine fever entering the UK, something that would have a devastating impact on agriculture and, in turn, offer a further incentive to those who wish illegally to import meat.

Given that the cost of living crisis has led to an increase in the illegal food trade, can the Minister elucidate the reasons for the proposed shift in customs checks from Bastion Point to Sevington, 22 miles from the Port of Dover itself? Defra’s rationale thus far seems to focus on cost but, given that concerns have been raised by industry sources at Defra forums, I suggest that it may be worth thinking again. The Dover Port Health Authority suggests that this change could easily lead to unexamined goods travelling 22 miles across the UK, with all of the attendant risks of possible infection, diminishing UK biosecurity. It claims it has not received appropriate assurances from Defra as to how existing standards could be maintained and that the Sevington facility, unlike Bastion Point, will not be operational 24 hours a day. Given the degree of concern expressed by the health authority and the UK food industry, does the Minister not agree that further work is needed before this change responsibly can be put into effect?

To return to the broader themes of this debate in the little time remaining, I join other noble Lords in welcoming the Government’s 2023 biosecurity strategy. Its ambitions, if realised, would make a genuine and substantive contribution to enhancing our biosecurity. I agree with the Centre for Long-Term Resilience that sustained resourcing will be critical in making its implementation a success. While the £1.5 billion being spent annually is welcome, have the Government considered a longer-term, multi-year funding settlement that would enable implementation to proceed securely and at pace?

I remind the Minister that the Government’s first biological security strategy was published in July 2018, just as Parliament was rising for the Summer Recess. To my knowledge, it was never debated in Parliament and while it warned of the need to co-ordinate government actions better and for a “truly comprehensive approach” to meet risks, including pandemics, it manifestly failed so to do, to such an extent that the parliamentary Joint Committee on the National Security Strategy, in its December 2020 report, found that Covid-19 exposed “profound shortcomings” in Britain’s approach to biosecurity.

As this debate makes clear, we face a variety of long-term biosecurity threats, and our response to these risks must be considered, proactive and durable to ensure that we keep this country safe.
