I hope the soft serve ice cream industry collapses overnight, just so I don't have to make parts for the machines anymore.
Also don't order soft serve ice cream. Those parts were made with acceptable levels of 'contamination' on an industrial press that's older than the moon landing. They only ever get a surface alcohol rub and that's only if there's grease on them. The distributor and then recipient probably do even less of a job to clean them. Unless you can see it getting dished out or mixed, avoid getting fast food dairy products.
