been looking at the title, but didn't want to read more bad news, bug then my brain thought this about something other than the actual real planetary food chain, and sure enough it's about industrialy made food substitutes. as to the fish meal catching fire, there are other solutions, pulling a partial vacume and flooding with CO², refrigerating/freezing, or useing other (fuck me), antioxidents, like various oils like chiken grease or hey!, fish oil, but of course Muney, jingle jangle muney muney muney, and the kind of people who own ship loads of fish meal, will never, see, smell, or eat any of the resulting comodities, so it's fine right. tried that janky salmon a few times, but never liked it, and stick to local caught fish from the ocean I could see if I were to stand up.

re: spontainous combustion, there is a biological process called 'the heat of evolution" that is used to describe the heat given off by ALL ripening and oxidising biological materials, and MANY foods will combust if packed too tight and insulated, case in point are bannanas that must be kept seperate and refrigerated and the whole bannana industry was built on specialy designed refrigerated ships, as there was no good way to ship them before refrigeration. as for 'heat of evolution' there are charts that give the btu's/ton per hour used in refrigeration design, as the heat is substantial and will overwhelm the systems, with fire a real possibility. this is different than dusts and powders exploding due to the 'right' mix and a spark, which might just possibly coincide with a decomposition fire, if a ship was that unlucky. but with so many ways that things can go wrong, it is astounding to find out someone got the idea to prevent food fires by covering everything in poison.
