There is to be a total withdrawal of a South Australian nachos meal linked with a case of botulism and the manufacturer is planning a refrigerated product if it is ever returned to store shelves.

A Melbourne man became paralysed after eating ‘Nachos to Go’ in January.

The pack’s cheese dip was considered suspect, with traces of botulism found in the residue of the discarded nachos.

The Dudley Park manufacturer Mexican Express had previously recalled only one batch but managing director Ian Young says it has decided to suspend production and totally remove the product from shelves.

"We just don’t want anything on our conscience — any risk is not acceptable," he said.

Mexican Express says the withdrawal follows talks with health authorities and a review of the product formulation.

The company says extensive testing of all other ‘Nachos to Go’ packets has returned negative results for botulism.
