I just love finding pieces of history! I checked on when we stopped getting sugar from Cuba. I copied this from this website

"In retaliation, in July 1960, Cuba’s sugar quota was cut from the US market when Eisenhower cut Cuban sugar imports by 700,000 tons, the balance of the quota for 1960. He then fixed any future quota at zero. This move was devastating because, under normal circumstances, Cuba sold an average of 3,000,000 tons of sugar each year to the United States, at “prices that had been kept artificially high by laws designed to protect the high – cost US producer.”"
