What happened

Whether it’s trimming off a piece of mushy parsnip or cutting away a slightly mouldy bit of apple, many of us have used produce long after their peak of freshness.

Why it matters

While fruits and veggies are important for our health, they’re also highly susceptible to bacteria, fungi and other pathogenic microbes.

Common ground

Overripe fruit and veg can harbour E coli, Salmonella and Listeria bacteria, all of which can cause food poisoning.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
