Police have arrested a woman over the food poisoning scare at two Sizzler restaurants in Brisbane.
The Sizzler chain has closed all of its self-serve salad bars in Australia after rat poison was found in food at two Brisbane restaurants.
Police have now arrested a 57-year-old woman in Brisbane's inner-city.
The man heading the investigation, Inspector Bob Hytch, says she will be charged later today.
"That person is currently at city CIB and we expect that she will be charged later in the day in the city watchhouse," he said.
"At this stage she is going to be charged under section 238 of the Criminal Code in relation to the contamination of goods.
"We do expect other charges to be laid, but as I said this arrest has only just been made and we are in the early stages of our investigation."
Employment concerns
Meanwhile, the union representing hundreds of Sizzler staff says it has grave fears for employment at the restaurant.
The Liquor, Hospitality and Miscellaneous Workers Union's Ian Burgett says the union has not spoken to management yet, but it is concerned jobs could be lost.
"It depends how long this goes on, until they get back to full operations," he said.
"A large number of their work force is young and casual and it could impact on those people."
Queensland, Australia police have charged a 57-year-old woman with the alleged contamination of the salad bar at two Sizzler restaurants.

Rat poison pellets were found in food at Sizzler restaurants at Toowong on January 20 and the Brisbane Myer Centre outlet last Sunday. Yesterday Sizzler closed salad bars nationwide, but they did not report the incidents to the Queensland Health Department until last Monday.  

Queensland’s Health Minister Stephen Robertson criticised the restaurant chain for delaying reporting a possible incident of food contamination for 37 days. "I think this is a case that - a real life case - that we should perhaps learn some lessons from,” he said.

Queensland Police Inspector Bob Hytch said the woman is the same woman police asked to come forward after she told Sizzler staff she had found pellets in soup at the Myer Centre restaurant last Saturday. 

The woman is expected to face Brisbane Magistrates' Court tomorrow charged with two counts of contamination of goods and four counts of an act intending to cause grievous bodily harm.
