Gulp: Adventures on the Alimentary Canal

Cow 101.5 was getting a hose bath from one of DePeters’s students, Ariel. Ariel and her array of piercings posed a welcome challenge to the stereotype of the conservative male ag major. We stood by, watching and waving away flies. I like the look of cows: the art-directed hide, their hips under their skin, the meditative sideways metronomics of the jaw.

The fistulated—or “holey,” as the students like to say—cow has been an ag-school standard for decades. My husband Ed recalls, as a child, hearing from his dad about the cow at Rutgers with “a window in its side.” The operation is simple. The bottom of a coffee can is traced with chalk on the cow, a topical anesthetic applied, and the circle cut from the hide, along with a matching opening in the rumen. The two holes are stitched together and the hole is outfitted with a plastic stopper. It is little more barbaric than the earlobe plugs of my local Peet’s barista or Ariel’s facial adornments. “The animal rights people come out here expecting a glass window with a sash and sill,” said DePeters. He handed me a protective plastic veterinary sleeve that extended to my shoulder and directed me to position myself to the side of the opening. When a fistulated cow coughs, if it has been eating, wet plant matter sometimes blows out of the hole.

DePeters took some photographs of me with my right arm in 101.5. The cow appears unmoved. I look like I’ve seen God. I was in all the way to my armpit and still could not reach the bottom of the rumen. I could feel strong, steady squeezes and movements, almost more industrial than biological. I felt like I’d stuck my arm into a fermentation vat with an automated mixing paddle at the bottom, and I basically had.

Ancient man was omnivorous—a scavenger as much as a predator. Often enough, his steak dinner was shared with millions of potentially harmful bacteria. Thus the human stomach, unlike the ruminant’s, concerns itself with disinfection more than holding capacity. But even scavenged meals were sporadic, and some degree of storage was needed. How compliant is the human stomach? That depends on what you use it for.

* Those of you who swallow oysters without chewing them may be curious as to the fate of your appetizers. Mollusk scientist Steve Geiger surmised that a cleanly shucked oyster could likely survive a matter of minutes inside the stomach. Oysters can “switch over to anaerobic” and get by without oxygen, but the temperature in a stomach is far too warm. I asked Geiger, who works for the Florida Fish and Wildlife Research Institute, about the oyster’s emotional state during its final moments inside a person. He replied that the oyster, from his understanding, is “pretty low on the scale.” While a scallop, by comparison, has eyes and a primitive neural network at its disposal, the adult oyster makes do with a few ganglia. And mercifully, it is likely to go into shock almost immediately because of the low pH of the stomach. Researchers who need to sedate crustaceans use seltzer water because of its low pH. Geiger imagined it would have a similar effect on bivalves. But you might like to chew them nonetheless, because they’re tastier that way.

* How remains a matter of debate. I had heard that pythons suffocate prey by tightening on its exhale and preventing further inhales. Secor says no; prey passes out too quickly for that to be the explanation. “You’d still have oxygen circulating in the blood, like you’re holding your breath.” He thinks it’s more likely that the constriction shuts off blood flow, more like strangulation than suffocation. An experiment was planned at UCLA but nixed by the animal care committee. Secor would volunteer himself. “I think we’d all like to have a giant snake constrict us in a controlled situation and see what happens—could we still inhale?” It’s possible he’s a little nuts. But in a good way.

* Excuse me, I mean the Dried Plum Capital of the World. The change was made official in 1988, as part of an effort to liberate the fruit from its reputation as a geriatric stool softener. Yuba City has Vancouver, Washington, to blame for that. The original Prune Capital of the World, Vancouver was the home of the Prunarians, a group of civic-minded prune boosters who, back in the 1920s, touted the laxative effects of dried plums. The Prunarians also sponsored an annual prune festival and parade. A 1919 photo reveals a distinct lack of festiveness and pruniness. Eight men in beige uniforms stand in a row across the width of a rain-soaked pavement. A ninth stands on his own just ahead of the row, similarly attired. Presumably he is their leader, though you expect a little foofaraw from an entity known as the Big Prune. Or the Big Dried Plum, as Yuba City would like you to call him.
