If you think you’ve had a bad day at work, spare a thought for whoever has to clean up this mess.

Over 100 cryogenic cylinders full of semen have exploded at a fire at Yarram cattle-breeding facility overnight.

The CFA was called to Yarram Herd Services just after 3am.

“There were quite a few explosions,” said the spokesman and it took 10 crews and two-and-a-half hours to get under control.
