■ When Joseph Ugalde, 38, a San Francisco marketing executive, goes out for lunch, he orders the Chinese chicken salad, the turkey avocado sandwich or sometimes the chicken pesto melt. But as of last month, one thing he will not order is tuna. No tuna salads. No tuna sandwiches. No tuna melts. “I love tuna melts,” Ugalde said somewhat wistfully. “Or I did.”
Now, however, Ugalde is boycotting tuna, which he used to eat once or twice a week, because of federal advisories about mercury in it.
“When you are seeing headlines about mercury splashed across newspapers, it puts up a little warning sign across your head,” said Ugalde, who recently warned a co-worker who was on the low-carbohydrate Atkins diet about the tuna she was eating every day.
