The Polish meat giant SuperDrob is sourcing chicken from factory farms that use medicines classified as “critically important” to human health, despite the grave risk this poses to consumers. SuperDrob sells frozen poultry products to Lidl, Asda and Iceland.

The company was linked to a fatal salmonella outbreak in 2020 – which TBIJ, the Guardian and ITV can now reveal involved bacteria resistant to multiple drugs – and there were at least 15 salmonella contaminations linked to SuperDrob poultry in the 18 months that followed.

Bacteria such as salmonella can easily spread on poultry farms, particularly where there are unhygienic or overcrowded conditions. The use of antibiotics on farms can enable potentially lethal bacteria to develop resistance, meaning the drugs will no longer work to treat infections. Antibiotic-resistant bacteria – known as “superbugs” – are a growing threat to human health, leading to an estimated 1.2 million deaths globally in 2019.

To reduce the risk of superbug outbreaks, EU legislation tightened up the use of antibiotics on farms as of last year. Yet the use of drugs critical for human health on farms in Poland, Europe’s biggest producer of poultry meat, has soared in recent years.

The country has accounted for more than half of serious salmonella contaminations involving meat originating in the EU since 2020. SuperDrob is one of Poland’s leading poultry producers and more than 50% of its revenue is from exports.
