Important people are incapacitated by food poisoning.
Needs a Better Title Eating. It's how we replenish nutrients and sustain ourselves. Not eating for a long period of time can lead to the body consuming it's own stores of muscle and fat. Starvation, not fun. So, it's not uncommon for a group of important people; a bridge crew of a cruiseliner, or the flight crew of a passenger aircraft or spacecraft, or even the engineering team of some heavy machinery, to have a hearty meal before they go on their mission. And then they find that their food was contaminated and they all fall to severe food poisoning, leaving the gear with no one to operate it. That cruiseliner goes off course, the airplane has no pilot, the machinery keeps operating with no controller. A fairly common precursor to a dramatic plot. The professionals have been rendered useless by their dietary intake and it's up to someone else save the day.
