In this photo taken Aug, 2, 2011, Ron Garthwaite, one of two raw milk producers in California, poses with a bull at Claravale Farm in Paicines, Calif. Garthwaite and his wife Collette Cassidy, who run the farm, say tighter government regulations make it hard for raw milk producers to survive. Despite increased demand from consumers, five states have adopted stricter standards to regulate unprocessed milk in the past three years, according to the Raw Milk Survey released in July.
