You thought SPAM was bad…
A couple years ago, I saw Arctic Passage: Prisoners of the Ice, a Nova episode about the last (and lost) Franklin expedition. Like all good ice-related stories of Victorian explorers, it involved the expedition making grand plans but ultimately getting overwhelmed by the weather conditions and dying. Sir John Franklin attempted to traverse the Northwest Passage (which exists, though it’s clogged with ice), got stuck along the way, and his entire crew died.
There were two things that really stuck with me about the story: the sailors spreading various sexually transmitted diseases among the Inuit (charming on so many levels), and the canned food supplies caused lead poisoning which sped up their deaths.
Evidence suggested that a combination of cold, starvation, and disease including scurvy, pneumonia, and tuberculosis, all exacerbated by lead poisoning, killed the entirety of the Franklin party. — Wikipedia
In 1845 when the expedition left England, canning was only a few decades old. And to seal the cans, manufacturers used solder… lead solder. The sick irony of that was very memorable — bring plenty of provisions, and get killed by them. Makes you grateful for modern science and food preservation, which prevents lead poisoning, botulism, and so on…
It turns out that more recent (September 2008) research suggests that the water system on board Franklin’s ship was responsible for the extreme lead levels, not the solder (or not solely the solder). They had a brand new furnace and a “Fraser galley” which would allow them to distill fresh water from seawater as they sailed (or as they were frozen in the ice). And since standard plumbing fixtures were made of lead… well, we’re left with an ironic poisoning. One of the modern features of Franklin’s expedition led to its downfall.
