Employees who poisoned patrons remain employees?

I find this story so bizarre that it's hard to believe. Are these the actions of real people? Just taking the text at face value, it implies that the managers and senior staff at Hungry Jacks knew that their employees had sprayed the cleaning substance on the food, but chose to make no effort to contact the affected patrons or the authorities until someone was admitted to the hospital. Hungry Jacks continues to maintain these employees despite their indirect violence toward patrons, and there's no word of the authorities actually preferring charges. The story then reassures us that there's a special law against "making food unsafe" in Australia. Really? To think there would be a law against this! I would have expected as much in Sumer or in Nineveh. Why is a specific law even needed? This is undoubtedly a species of assault. On Wikinews it's stories like these, about local criminal matters, that seem to make the least sense. Does nobody else but me think this is a serious crime?

Actually; Josh's boss was Luke at the time. Only two employees could have even possibly been involved, as there was limited staff (3 in total), one of which had to remain out of the kitchen due to general OH&S policies. And no action was taken against them. I was previously employed, and the staff that night would not have purposefully sprayed these burgers. There are many other ways the burgers could have been contaminated with chemical, such as a spill, or some of the spray remaining on the work bench. The Hungry Jacks Bathurst employees may be a little on the slow side, but they are not stupid enough to spray food with harmful chemicals.
