The new owner of a popular Vietnamese restaurant, in Brisbane's West End is desperately trying to salvage its reputation, after being accused of poisoning eight customers with salmonella.

Maria Nguyen bought the business off David Duong after council health inspectors last year discovered pigeons in the kitchen, black slime near food preparation areas and raw meat defrosting on the floor underneath dirty dishes.

Nguyen said she feels misled claiming Duong, who is now facing more than 50 food safety charges, never disclosed the serious health breaches.
