Bellone, New York Blood Center declare blood emergency

Suffolk County Executive Steve Bellone and the New York Blood Center have declared a blood emergency.
The emergency means there is less than a two-day supply for the universal blood type O-negative.
 Officials say in order to maintain a safe blood supply, a seven-day inventory of all types must be continually replenished.  
Companies, organizations and community groups are encouraged to step up to host a blood drive in July or August to help rebuild the blood supply.
