120.54(4)(b), Florida Statutes, states that those rules pertaining to perishable agricultural commodities shall be included in the definition of rules relating to the public health, safety, or welfare. Due to adverse growing conditions over the last 10 years due to Huanglongbing (“HLB” or “Greening”) disease significant amounts of the Florida grapefruit crop in the 2017-2018 season will have a minimum ratio of total soluble solids to anhydrous citric acid below the eight to one, seven to one, and six and one-half to one as well as the minimum brix of 7 established in rule. The unexpectedly chilly weather has exacerbated this issue, causing the fruit to mature at a lower brix and solids to acid ratio than is normal at this time of year. The inability to utilize this fruit would cause economic waste by allowing good and safe food to be ruled immature. After taking testimony and discussing the matter at a telephonic meeting and hearing in Bartow, Florida on December 14, 2017 the Florida Citrus Commission found that there exist unusual weather conditions which could cause a substantial portion of the grapefruit crop to fail maturity requirements. They voted unanimously to adopt Emergency Rule 20ER17-4, lowering the minimum ratio of total soluble solids to anhydrous citric acid and the minimum Brix requirement for grapefruit for processing for the period of December 15, 2017 through April 14, 2018, both dates inclusive.
