Australians have stopped eating salad in the aftermath of the salmonella outbreak as growers across the country report a drop in sales from wholesalers.
As it emerged that potentially contaminated greens had been exported to three Asian countries, grower representative body AUSVEG said the outbreak linked to leafy greens from a Victorian business, Tripod Farmers, had had a "substantial impact", even on growers in other states. 
New figures from health authorities show the number of cases associated with the Salmonella anatum outbreak have climbed to 128, and 100 of those are in Victoria. The Victorian figures include nine confirmed cases and 91 probable cases.
The Victorian Health Department on Wednesday said lab tests were continuing and the national recall for several salad leaf products was still in place: "Consumers are advised to be aware of the signs and symptoms of gastroenteritis which may be caused by the salmonella bacterium."
Consumer concern about the salmonella outbreak is hurting growers at the summer peak and during the barbecue season, a time when leafy greens are normally in demand.
"What we have seen is a very immediate impact on growers. We've got a lot of growers around the country who grow leafy veg. This incident was confined to just one growing operation, but all of these growers seem to have been feeling the impact," AUSVEG national manager, scientific affairs, Jessica Lye said.
"The impact can't be quantified at the moment, but we are receiving reports from growers; they're reporting a drop in sales."
"What we'd like to really emphasise is [that] our growers have been doing it tough for the last few years, with farmgate sale prices going down, and the input costs such as fertiliser, electricity and water are always going up. So it's getting more and more difficult for our growers to make a profit."
Dr Lye said food safety incidents in the nation's vegetable industry were "exceedingly rare" and consumers could be confident in the produce available.
"This recent recall is not indicative of a systematic food safety issue in the vegetable industry. It is limited to one supplier, and all affected product has been taken off the shelves," she said.
A Senate estimates hearing on Wednesday heard that Tripod had exported 23 consignments of the "same sort of product" to Thailand, Singapore and Hong Kong.
In response to questions by Senator Rachel Siewert, Department of Agriculture officials said Thai authorities had heightened inspections, but no bans had been put in place.
"We have written to those three countries involved, with 23 identified consignments that may contain lettuce from that particular establishment," said Chris Parker, assistant secretary of the department's plant export operations branch.
"This is regular business that we would clearly notify our trading partners when issues may or may not arise and it is something they would do for us as well."
An Australian Red Cross Blood Service spokeswoman said the salmonella scare had had no impact on the safety of blood supply.
