Mr. Girgis lives with his extended family, about 30 people, in the first two floors of a building that leans against a cliff. His 60 small pigs live on the ground floor. They have dark, furry skin, and their squeals can be heard a block away from Mr. Girgis’ home.Many of Cairo’s pig farmers live in similar conditions, sharing their small spaces in the teeming city with their animals. After international health officials criticized Egypt’s decision to kill about 300,000 pigs, the Agriculture Ministry’s head of infectious diseases, Saber Abdel Aziz Galal, explained that the cull was “a general health measure,” according to Agence France-Presse."It is good to restructure this kind of breeding in good farms, not on rubbish," the agency quoted him as saying.“We will build new farms in special areas, like in Europe,” he said. “Within two years the pigs will return, but we need first to build new farms."
