Of course this is happening. They're commies. Food shortages are happening in Venezuela too. They'll probably start happening in Argentina - a food exporter - too.
The good thing is that Cuba is slowly reforming its economy. Its only a matter of time before Cuba ditches that anachronism called communism.

Cuba, one of the world’s last surviving Communist states, is looking at watering down the generous social welfare system that has been a cornerstone of its economy for nearly 50 years, according to a senior government official.
Alfredo Jam, head of macroeconomic analysis in the economy ministry, told the Financial Times that Cubans had been “over-protected” by a system that subsidised food costs and limited the amount people could earn, prompting labour shortages in important industries.
“We can’t give people so much security with their income that it affects their willingness to work,” Mr Jam said. “We can have equality in access to education and health but not in equality of income.” He said the emphasis on equality had helped maintain social cohesion during the 1990s when Cuba’s economy came close to collapse after the withdrawal of Soviet assistance, but “when the economy recovers you realise that there is [a level of] protection that has to change. We can’t have a situation where it is not work that gives access to goods,” he said.
