MOX, luxury food and alien organisms are all <<Highly Perishable>> which means they have a short 'shelf life'. Every few minutes one (1) unit will expire in your hold. So if you spent, say $800 per alien organism on the way to Cambridge Research trying to make $2,000 each then just do the math.
You lose $800 in the initial investment and have to make it up out of the profit from the remaining cargo. That means your surviving cargo is only worth $400. ($1,200 profit each minus $800 for each dead, stinking organism = $400) Then there's the clean-up fees, burial etc. from ALG.
So, in the end *avoid* all combat and diversions with perishables.

I know it's not the right forum so be warned:
** SPOILER **
You can minimize your loss of perishable goods: just land everywhere and sell your cargo. Buy it back immediately (for the same price). They are all 'fresh' now. Start again and head to the next station/planet.
Obviously this is very slow traveling. You cannot save EVERY commodity but you will arrive with more than 90 % - but it's hard earned money.
So don't do that with 10 Alien Organisms. But with a cargo hold of 275 it will bring you about 500'000 $ per run

Ohhhhhhhh, It all becomes clear now.

Some people are like slinkies. They don't do anything, but you can't help but smile as they tumble down the stairs.
