Conservative MP Anne McIntosh said reports that cottage pie delivered to schools in Lancashire has tested positive for horse DNA were "deeply worrying".
The Environment, Food, and Rural Affairs Committee chairman said she was "not convinced" the contamination in the wider food chain affecting British food was taking place in the UK.
And she told Andrew Neil about the changes in the supply chain for British supermarkets: "I don't think we will ever see that level of complacency ever again"
