Swine Flu's Ground Zero?: Factory Pig Farming

Everyone told Maria del Carmen Hernandez that her kindergartner's illness was a just a regular cold. But it seemed like the whole town of 3,000 was getting sick.

As early as February, neighbors all around her were coming down with unusually strong flu symptoms — and the caseload kept growing. When state health workers came to investigate March 23, some 1,300 people sought their medical help. About 450 were diagnosed with acute respiratory infections and sent home with antibiotics and surgical masks.

Five-year-old Edgar Hernandez was still healthy then. Hernandez wanted to keep him home from school so he wouldn't get sick, but her husband said, "we can't be afraid of what might or might not happen."

Then he came home with a fever and a headache so bad his eyes hurt. She took him to a clinic, and after a few days of antibiotics, he too recovered.

No one told Hernandez that her son had become Mexico's earliest confirmed case of swine flu until the Veracruz governor helicoptered in on Monday. But Edgar's case confirmed for residents what they already believed: their hillside town is ground zero in the epidemic.

Local health officials and Federal Health Secretary Jose Angel Cordova downplay claims that the swine flu epidemic could have started in La Gloria, noting that of 35 mucous samples taken from respiratory patients there, only Edgar's came back positive.

That confirmation that the boy was infected with H1N1 — a strange new mix of pig, bird and human flu virus that has killed as many as 152 people in Mexico and now spread across the world — wasn't made until last week, when signs of the outbreak elsewhere prompted a second look at his sample.

"If the people who are supposed to be familiar with this didn't know what it was, how will we ever know how my son got it?" Hernandez said Tuesday.

Hernandez said doctors came from Jalapa, the state capital, and Veracruz city to see Edgar in the weeks after he was tested. But they said nothing, "they just wanted to see him." A team came again last weekend, after federal officials confirmed the swine flu cases late Thursday and started closing schools and canceling events in Mexico City.

Again, they left without saying anything, she said.

Cordova insists the rest of the community had suffered from H2N3, a common flu, based on other 34 samples. While Mexican authorities haven't determined how or where the swine flu outbreak began, Gov. Fidel Herrera said Tuesday that "there is not a single indicator" suggesting it started in La Gloria.

But Jose Luis Martinez, a 34-year-old resident of the town, made the swine flu connection the minute he heard a description of the symptoms on the news: fever, coughing, joint aches, severe headache and, in some cases, vomiting and diarrhea.

"When we saw it on the television, we said to ourselves, 'This is what we had,'" he said Monday. "It all came from here. ... The symptoms they are suffering are the same that we had here."

Townspeople blame their ills on pig waste from that lies upwind, five miles (8.5 kilometers) to the north. The toxins blows through other towns, only to get trapped by mountains in La Gloria, they say.

Granjas Carroll de Mexico, half-owned by Virginia-based Smithfield Foods, Inc., has 72 farms in the surrounding area. Smithfield spokeswoman Keira Ullrich said the company has found no clinical signs or symptoms of the presence of swine influenza in its swine herd or its employees working at its joint ventures anywhere in Mexico.

Animal health expert Peter Roeder, a consultant to the UN's Food and Agriculture Organization, said many possibilities exist for how the virus first jumped to humans, and that it could have happened months or even a year ago.

Roeder said it's possible someone tending the pigs could have passed a human influenza virus to a pig already infected with another type of swine flu, and then that pig could have also come into contact with a bird virus. Then, the new H1N1 virus formed could have been transmitted back to the workers.

But that's just a theory — and no one has any evidence that it happened in La Gloria.

"It's all surmise," Roeder said by phone from the Philippines. "The only thing that we know is that we have a virus that is transmitting between people and it is causing some concern."

But residents say they have been bothered for years by the fetid smell of the farms, and they suspect their water and air has been contaminated by waste. Local health workers intervened in early April, sealing off the town of La Gloria and spraying to kill flies people said were swarming around their homes.
