-55- Northeast Area.--All producers supplying the Northeast milk marketing area were located within the fourteen-county area (Figure 6). Total receipts at area plants were 29,586,000 pounds for the two months. This was 93.4 percent of the total sales of milk by area producers. The major portion of farm shipments was sold to dairy plants in Duval County. Dairy farmers in Duval County, the most heavily populated within the area, supplied 18,112,000 pounds of milk to area plants. This was 61.2 percent of market receipts from Florida producers. Clay County dairies were second with 6,267,000 pounds, which was 21.2 percent of supplies. A portion of total supply was received from each county in the area. Levy County was the lowest with 44,000 pounds, or 0.1 percent of total producer milk deliveries. Central Area.--Milk receipts at dairy plants in Central Florida originated in all of the eleven counties in the area, four counties in Northeast Florida and one county each in the Southeast and Tampa Bay areas. Total market receipts for the months of April and October 1959 were 23,838,000 pounds. Dairy farmers within Central Florida counties accounted for 21,625,000 pounds, or 90.7 percent of receipts from Florida producers. Northeast area milk producers shipped 1,734,000 pounds, which was 7.3 percent of the total supply. Tampa Bay and Southeast dairy farms delivered 1.5 and 0.5 percent of producer milk supply, respectively. During the two-month period, 21.4 percent of the total area output was delivered to plants in other areas. Plants in the Tampa Bay area received 3,630,000 pounds of milk from Central Florida producers. Ship- ments to Southeast Florida were 2,253,000 pounds. Thus, while the market received a considerable portion of its total milk supply from adjacent areas (9.3 percent), an even greater amount was shipped on a regular basis by local producers to other milk marketing areas (21.4 percent). Data on supply area locations, movement patterns and volumes are presented in Table 31 and Figure 7. Tampa Bay Area.--Milk processors in Tampa Bay received fluid milk supplies from producers located in two other areas of Florida in addition to local dairy farms. The total milk supply originating within the eleven-county Tampa Bay area was 46,787,000 pounds in April and October. This was 0.3 percent less than total plant receipts from all regular supply sources. Of the total local production, 363,000 pounds were shipped to Central Florida processors and 3,320,000 pounds were delivered to plants in the Southeastern market. The county with the largest volume of sales to area plants was Hillsborough. Fifty-seven percent of all locally produced fluid milk originated on farms within that one county. Producers in the Central Florida counties of Orange, Polk and Sumter delivered 7.7 percent of total market receipts in the period (Figure 8). Hendry County producers accounted for 213,000 pounds or 0.5 percent of milk supply. Thus, approximately 8.2 percent of market
