Contrary to popular belief, most people don’t find the odor from hog farms offensive, according to a recent University of Arkansas study.
The survey of 36 randomly selected hog farms in seven Arkansas counties showed that 85 percent of the odors from hog farms were not offensive.
Seven panels made up of 42 people used their noses and a scentometer device to conduct 1,157 measurements.
Measurements were made at distances ranging from less than 200 feet up to one mile. Of the 1,157 odor measurements, 57 percent were classified as nondetectable, 28 percent detectable but not offensive, 13 percent mildly offensive and 2 percent strongly offensive.
Seven producers whose hog manure contributed to the study indicated they were using or had used an additive to help control odors.
