CAL-MAINE FOODS REPORTS
FIRST QUARTER FISCAL 2010 RESULTS





JACKSON,
Miss. (September 28, 2009) 3⁄4 Cal-Maine Foods, Inc.
(NASDAQ: CALM) today announced results for its first quarter of fiscal 2010
ended August 28, 2009.





For the
first quarter of fiscal 2010, net sales were $187.7 million, compared with net
sales of $206.9 million for the first quarter of fiscal
2009.  The Company reported net loss of $3.8 million, or $0.16
per basic and diluted share, for the first quarter of fiscal 2010 compared
with net income of $11.1 million, or $0.47 per basic and diluted
share, for the year-earlier period.





Fred Adams, Jr., chairman and chief
executive officer of Cal-Maine Foods, Inc., stated, “All factors
considered, our results for the first quarter of fiscal 2010 were
satisfactory.  Both the number of eggs sold and eggs produced by Cal-Maine
were up over the prior year, however, selling prices were
lower.  Our feed costs were down considerably from the same period
last year, but not enough to offset the price decline.  Demand for eggs at
the retail level remained strong; however, institutional sales
to restaurants and food service customers have been weaker, reflecting
the current economy.





“USDA
reports indicate that the egg supply for the year ahead should be balanced with
demand.  Corn and soybean production are also projected to be adequate for
usage.  We are projecting lower feed costs for the year ahead. 
All of our operations are running smoothly and efficiently,” added
Adams.





Under
Cal-Maine’s dividend policy, no dividends are paid if there is a loss for the
quarter.





Selected operating statistics for the
first quarter of fiscal 2010 compared with the prior year period are shown
below:
