Romper, a site targeting new moms (from the same folks who run Bustle) deconstructs recent listeria events and sorta misses stuff, but there are some gems for the nerds:

Listeria is a wild bacteria

As opposed to the domestic ones.

it’s possible that a listeria contamination happened before the veggies were frozen, hence that “voluntary recall” qualifier for companies.

Huh?

Want to ensure listeria doesn’t live…refrigerate.

Uh no. Not quite

If you feel icky about bacteria, forget about what your grandma said and toss that pasta. If not, go for it. Just microwave them at least.

Probably not the best cooking source because of the uneven heat.

At least they got this correct:

Different kinds of food are processed, cleaned, and distributed in many places.

Yep.
