Shredded Wheat

One day there might be a situation
When you feel a strong inclination
To eat a nice bowl of shredded wheat
But it is no longer such a treat

What if a poisonous substance
Was found in the wheat in abundance
What would you say to raise the alarm
Before people come to any harm

Naturally, you'd want to tweet
'Never eat shredded wheat'
But no one will think the cereal's infested
They'll just think 'North-east south-wested'
They'll get infected

So how do you get the message out?
What is the phrase you should shout?
Try these phrases out for size
Nailing each is super wise

Notify everyone something's wrong
Nestle equals 'sick week long'
Nice? Eh, sub-par Weetabix
Next explain situation to Katy Wix
Not enough sensible words
Now everyone's sleeping in wards
Naughty Edward sometimes whispers
No Edward, stop whispering
Nasty Edward shouts "Wusses!"
Everyone thinking of compasses
Thinking of compasses
