This guy did it to get away from a police dog. Who's the culprit?

Police dog bitten by suspected hijacker

Flights from Johannesburg to London and elsewhere have regularly been fumigated in the last 20 odd years (I cannot vouch on an annual basis, but it's something I've experienced many times).

What usually happens is an announcement is made that due to some-or-the-other health regulation, fumigation is required, please cover your mouth/ nose/ eyes, if you think there will be a problem, please contact the crew. Then crew members walk briskly with some spray through the cabin, it smells weird and sweet for a while and the usual announcements commence. I haven't thought about implications for people with breathing sensitivities, but the way it's written sensationalizes something that's essentially a non-story, almost like saying "did you know, on a daily basis, people drive *cars* to work!"
