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 modifications.  No new hog farms have been constructed for greater than 20 years, lots of 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 remedy lagoons to keep up sufficient storage within the occasion of heavy rains. And as storms method, farmers put together for potential energy outages, flooding and different disruptions by positioning turbines and animal feed on farms and at key areas in hog-producing counties. When essential, animals are moved to greater floor or despatched to market early.


Ninety-eight % of all hog lagoons within the state noticed minimal impression 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 instances — 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. Nonetheless, 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.


Previously 20 years, greater than 300 hog lagoons in NC have been completely closed.

Since Hurricane Floyd in 1999, 43 hog farms and 103 lagoons positioned within the 100-year floodplain have been completely closed by 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 remedy crops signify a better risk than hog farms.

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

Against this, municipal sanitary wastewater remedy amenities have discharge permits and through a storm, the system could overflow or be instantly bypassed. The NC Division of Environmental High quality reported that greater than 200 municipal wastewater remedy 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 targeted on our (municipal) wastewater remedy amenities as a result of there are most likely orders of magnitude extra human waste that has escaped these wastewater remedy amenities than what has escaped these pig lagoons.”


Watch out for pictures claiming to indicate flooded hog farms.

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

When hurricanes method, 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.
