The report in Asian newspaper Eastern Eye, highlights concerns raised by shopkeeper Besharat Rehman, who owns a halal supermarket in Bradford, West Yorkshire.
Mr Rehman told the paper: "A customer informed us that Sensations Thai Sweet Chilli and Doritos Chilli Heat Wave are not on Walkers' alcohol-free list. Our suppliers were unaware of this.
"Even if it is a trace amount of alcohol, Walkers should make it clear on the packaging so that the customer can make an informed choice.
I'll drink to that.
