According to Buckingham, the post-Brexit inspections phased in last year do represent a more stringent system than was previously in place. “Pre-Brexit, we didn’t check EU products of animal origin because […] the principle of ‘free circulation of goods’ applied between member states.”

TBIJ’s revelations come as Parliament’s environment, food and rural affairs select committee prepares to launch an inquiry into animal and plant health next Tuesday. Imported animal products will be a central focus of an initial evidence gathering session that will assess the effectiveness of import controls on biosecurity, food hygiene and public health.

The internal UKHSA records obtained by TBIJ also reveal that while a ban on Polish poultry products was among the measures being considered by the FSA, concerns remained about its potential effects on the meat industry. They included the possibility that the UK could import chicken from other countries with food safety “hazards”. No ban was subsequently implemented.

Although earlier FSA interventions brought about a reduction in reported cases, rates were still “outside of the tolerance that the FSA Board can accept of salmonella entering the UK from the EU”.

Officials were also worried that the salmonella contamination had become more widespread, involving multiple producers from Poland and a greater number of food products, the documents show. While attention had initially focussed on breaded chicken and other highly processed products, testing had revealed that fresh chicken and raw pet food was also implicated.

Richard Griffiths, chief executive of the British Poultry Council, said: “We expect our trading partners to meet their responsibilities with regard to safe food. If they cannot, and their own authorities cannot enforce the appropriate controls, then we want our own regulators to have the powers and resources to stop unsafe meat entering the country.”

The BPC previously called for every consignment of Polish poultry to be checked at UK borders.

Tests revealed that in 2024, at least 138 consignments of exported poultry from Poland contained salmonella, including variants that can be highly harmful to human health, according to EU data. The UK was among the affected countries. The figures were only slightly down from 2023, when there had been 149 recorded cases of contaminated products.

In June 2023, TBIJ reported that some of the salmonella linked to Polish poultry that poisoned UK consumers was resistant to multiple antibiotics, limiting treatment options for those falling seriously ill. The UK government was found to have allowed food companies linked to the outbreak to continue supplying supermarkets even after contaminated meat had been linked to the deaths of four people, and the poisoning of hundreds more.

Investigations also found that even though some of the salmonella was known to be antibiotic resistant, food safety and health officials did not disclose this to frontline health workers, including those treating victims. Nor did they inform the Polish authorities, impeding possible investigations into practices on the farms involved.
