world's largest pig slaughterhouse
A few years ago, I was a foreman in the Special Services dept. of a large electrical contractor. I was sent to TarHeel, North Carolina as part of the Process Controls/ Automation Group, to help oversee the final controls wiring of several large panels & systems. The plant was the world's largest hog slaughterhouse, and had been under construction for a year and a half at the time I was there, by the Stellar Group out of Jacksonville,Florida.
Anyway, I had to engineer and build a small panel in the sewage plant out back (bigger than the plants in small cities) to control some flow valves. We built it in the office trailer, then had to hook it up in place, and troubleshoot it. They had just started up operations that week, pigs were being brought in and processed. Everywhere you looked outside the doors of the sewage plant, were small-to-medium sized puddles of puke, most dried, a few recent. The smell from the plant was horrible. I used my company-issued (strict requirement by the Stellar Group)foam earplugs as nose plugs, and did a lot of mouth breathing. Got to where I swore I could just about taste it.
Not only that, but the safety director for the Stellar Group about went ballistic on me, when he saw me. He tried to get me thrown off the jobsite, before my boss managed to stop laughing long enough to convince him my hearing loss was real, and pre-existing, thereby erasing any legal obligation to wear them in the right holes

. There was a run on earplugs for several days after others saw me, pretty soon everyone was wearing 2 sets, one for the ears, the other for the nose... .
The sights and smells in that plant affected me so much that it was a full 2 years afterwards before I could eat any pork products... .
