Grower representative body AUSVEG said the recent salmonella outbreak linked to leafy greens from a Victorian business, Tripod Farmers, had had a "substantial impact", even on growers in states unaffected by the recall.

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.

A statement from the Victorian Health Department on Wednesday said laboratory testing was 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 green salad vegetables are normally in high 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," she said.

"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 incidences in the nation's vegetable industry were "exceedingly rare" and consumers could be confident in the fresh and pre-packaged vegetable products 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.

Last week, Tripod Farmers managing director Frank Ruffo​ said the company was focused on the health and safety of consumers, establishing the cause of the problem, and fixing it.

He said the company was working closely with health authorities to determine the cause of the issue and its extent.

An Australian Red Cross Blood Service spokeswoman said the salmonella scare had had no impact on the safety of blood supply.

"Nor do we expect there to be, due to our thorough donor screening practices," she said.

"Regarding salmonella, donors who have consumed contaminated products and become unwell would be unable to donate, and would be deferred [and asked to come back when feeling better] during the screening process prior to giving blood," she said.
