From the genus name Listeria.

(Can we date this quote?), Kaarin Goodburn, “How chilled is your fridge?”, in Food Standards Agency:
- One of the main reasons fridge temperatures are recommend to be set at 5ºC is because of listeria. Listeria is a food poisoning bacterium that is psychrotrophic – in other words it likes cold temperatures. From the growth models, we know that listeria grows nearly twice as fast at 8°C as it does at 5°C, hence the recommended 5ºC, which helps keep us safe from listeria.
