The threat of leaving crops un-harvested in Alabama has led that state's agriculture commissioner to suggest prison labor may be used to work the fields.
Knight said the hit should be blunted some by the effective use Mississippi farming operations have made of the federal guest worker program, but overzealous enforcement could quickly lead to huge losses of labor.
Poultry producers are particularly concerned that a crackdown on immigrant workers at processing plants in the state could dry up demand, said Knight.
"If they can't get the labor to run those plants ... our farmers aren't going to have chickens in their chicken houses," he said.
Mark Leggett, president of the Mississippi Poultry Association, is not terribly worried. The large processors who make up the bulk of the state's $2.5-billion poultry industry have been using the federal E-verify system the past three years, he said in an e-mail.
"Some use additional methods, in complying with applicable laws," Leggett said.
With an estimated 45,000 workers, 22 processing plants and about 2,000 farms, poultry is Mississippi's top agricultural commodity. Most of the processing plants and poultry farms are concentrated in East Central and Southeast Mississippi.
Hood said some fairly large raids on poultry plants five or so years ago led processors to "start taking care of business a little better."
They have created a pipeline for bringing on documented workers through the federal guest worker programs, he said, and are able to draw in replacements for those whose work permits have expired and must return to their home countries.
"They have situated themselves to where they are not going to be scrambling because they have workers lined up six months in advance," Hood said.
State Sen. Joey Fillingane, R-Sumrall, struck out last year in his attempt at passage of legislation to require local police to enforce federal immigration laws. He said he intends to resume the fight in the new session.
Fillingane said he wants Senate lawyers to review Alabama's stringent illegal immigrant law to determine what parts of it could be legally incorporated into a Mississippi law.
Alabama's law makes it a crime to harbor illegal immigrants or rent them an apartment. It also prohibits them from entering into contracts for such things as utilities and prohibits schools from enrolling students without proper documentation.
The law bars illegal immigrants from enrolling in any public college.
Fillingane said he has heard concerns from growers of blueberries and other crops in his district.
