On August 7th Adelaide Zoo was reported selling an ice cream which includes palm oil and is not made locally (1), one week later they’ve decided to switch to a local brand with no palm oil (2).
Another article mentions “Zoos SA chief executive Elaine Bensted admitted the zoo had underestimated the strong level of support for a local business.” (3) and Nick Xenophon may have had some input (4). Was people power responsible for the change?
