New York - The demand for kosher foodservice has soared to new heights, according to sources in the kosher food service. In interviews with officials involved in foodservice, it seemed that Mt. Sinai’s cutbacks to its kosher program at Beth Israel Medical Center in New York were an aberration to an otherwise “exploding” category. They cited dramatic increases in the school-aged and nursing home populations as examples of what is driving the expansion. Restaurants and other food programs such as universities, long-term care facilities and stadiums were also driving sales. Many new hotel programs, particularly on Passover were adding to what is now considered more than 40% of annual US kosher food sales of $2.5 billion. There are a number of distributors that serve foodservice with the largest being S. Bertram in Linden NJ. Sources said that kosher foodservice has grown by about 10% each year in just the last there years.
