A worker was filmed peeing and picking her nose into an ice cream machine, police say.
Jung Soon Wypcha is said to have urinated into the dessert churning machine at Lu Lus Ice Cream in Indian Shores, Florida, last month.
Afterwards, she reportedly emptied her waste out into a sink used to rinse out the equipment and bowls.
Wypcha, who worked in a business close to the ice cream shop, was reportedly also seen shoving her hands into ice cream cartons without washing her hands.
And the incriminating footage is said to further show her spitting into ice cream cartons.
Her alleged rampage is said to have forced Lu Lus to close down for deep cleaning.
They are said to have been forced to spend $2,000 on cleaning equipment and throwing away tainted products.
Wypcha was arrested on Monday and charged with criminal mischief, as well as violating Floridas Anti-Tampering Law.
