inoculate
ih-NOK-yoo-layt
/ɪˈnɒk.jʊ.leɪt/
To introduce a microorganism, spore, or active culture into a substance to initiate growth, fermentation, or aging.
Inoculate implies a highly deliberate, precise introduction of a specific microbe, rather than accidental exposure.
The story behind the word. This word has a beautiful agricultural history. It comes from the Latin 'inoculare', which meant 'to graft a bud from one plant into another'. The root 'oculus' means 'eye', which was also the Latin word for a plant bud. Over centuries, grafting a bud evolved into 'grafting' or introducing microbes into a body or food.

Memory hook
Think of putting an 'eye' (oculus) into the food. You inoculate it so the food can 'see' how to grow. Inoculate is to put the microbe in to make the magic begin.
When not to use
Do not use when microbes land on food by accident; that is contamination, not inoculation.
