Hurricane season is formally right here and NC State researchers have predicted an above-average season with 17-21 named storms. Listed below are 5 issues to bear in mind as we enter hurricane season.


Issues have improved dramatically prior to now 20 years.

It’s true that greater than twenty years in the past, the depth of Hurricane Floyd caught many hog farmers off guard. However the business didn’t waste time in making adjustments.  No new hog farms have been constructed for greater than twenty years, a whole lot of lagoons in flood-prone areas have been voluntarily closed, and the business has been proactive in making hurricane preparations a year-round observe.

Lengthy earlier than hurricane season arrives, farmers fastidiously handle therapy lagoons to take care of satisfactory storage within the occasion of heavy rains. And as storms strategy, farmers put together for potential energy outages, flooding and different disruptions by positioning mills and animal feed on farms and at key places in hog-producing counties. When needed, animals are moved to increased floor or despatched to market early.


Ninety-eight % of all hog lagoons within the state noticed minimal affect from Hurricane Florence.

NC hog farms have fared properly throughout devastating hurricanes.

Throughout Hurricane Matthew and Hurricane Florence — two of essentially the most substantial hurricanes to hit North Carolina in fashionable occasions — pig farms skilled restricted impacts. Throughout Florence, rivers swelled to report heights and full communities had been inundated by flood waters. However greater than 98% of lagoons efficiently withstood the floodwaters and skilled little or no harm.

That’s to not say there have been no impacts in any respect. A lot of the affected farms had been inundated by floodwaters, whereas a handful of farmers skilled structural points with their lagoons. Nevertheless, monitoring by the NC Division of Water Assets discovered no long-term results, concluding that the sheer quantity of rainwater has a diluting impact and ends in decrease than regular concentrations of pollution.


Prior to now 20 years, greater than 300 hog lagoons in NC have been completely closed.

Since Hurricane Floyd in 1999, 43 hog farms and 103 lagoons situated within the 100-year floodplain have been completely closed by means of the NC Swine Floodplain Buyout Program. Extra funding was secured in 2018 to broaden this system, with assist by the pork business.

As well as, the NC Basis for Soil and Water Conservation has closed 231 out-of-service lagoons.


Spills from municipal waste therapy crops characterize a higher menace than hog farms.

By design and by regulation, hog lagoons have a non-discharge allow and farmers should keep a “freeboard” of roughly 19 inches to guard the structural integrity of the lagoon and to soak up important rain occasions. Most farmers keep a decrease freeboard throughout hurricane season in anticipation of one other 500-year storm.

In contrast, municipal sanitary wastewater therapy services have discharge permits and through a storm, the system might overflow or be straight bypassed. The NC Division of Environmental High quality reported that greater than 200 municipal wastewater therapy crops spilled roughly 121 million gallons of sewage into our state’s waterways throughout Hurricane Florence.

Following that storm, DEQ Secretary Michael Regan mentioned: “We’re actually centered on our (municipal) wastewater therapy services as a result of there are most likely orders of magnitude extra human waste that has escaped these wastewater therapy services than what has escaped these pig lagoons.”


Watch out for pictures claiming to point out flooded hog farms.

Throughout latest hurricanes, media are sometimes fast to label flooded buildings in rural areas as a hog barn. They’ve inaccurately posted pictures of municipal waste crops, poultry homes and different agricultural services that had been labeled as hog farms.­­

When hurricanes strategy, we urge warning when reporting details about our farms and our business. Throughout and after storms, our workers will attain out and share correct and well timed details about the impacts on North Carolina’s pork business.
