An Esperance couple say they find a live frog inside a sealed bag of Woolworths lettuce during a routine grocery shop. Multiple reports describe the family as being shocked after discovering the animal when unpacking their purchase. The incident prompts an investigation, according to coverage from both a Perth-based newspaper and a national TV outlet. The reports indicate the frog was found within the lettuce bag despite it being sealed at the time of purchase. Details on how the frog entered the packaging, the product batch, and the condition or handling of the animal are not provided in the supplied summaries. The accounts focus on the discovery itself and the response by authorities or company processes leading to an investigation. Overall, the stories present a consistent sequence: a sealed lettuce bag is purchased, a live frog is discovered in the bag after it is brought home, and an investigation is launched following the complaint.
