As part of a national retail egg quality study, the variety of shell eggs a
nd egg products offered for sale, type of packaging and price relationships
were compared in five major metropolitan regions. A total of 81 stores in
28 cities were sampled in California (CA), Illinois (IL), North Carolina (N
C), Texas (TX), and New England (NE). Data were recorded for the variety of
brands, sizes, white or brown shell eggs, specialty eggs, liquid or frozen
eggs, carton sizes, package labeling and Coding, and price relationships o
f shell eggs, liquid, and frozen egg products displayed for sale.
The total variety of shell eggs displayed per store was the greatest for CA
and NE stores. Stores in CA and TX offered more (P < 0.05) variety of whit
e shell eggs than did stores in the other states, whereas stores in NE disp
layed the greatest variety (P < 0.05) of brown shell eggs. The average numb
er of liquid and frozen egg products was highest (P < 0.05) for NC stores.
Packaging type, USDA labeling, and carton coding differed somewhat among st
ates. The price per one dozen cartons of all white shell egg sizes was high
est (P < 0.05) in CA stores, and the average liquid plus frozen egg product
prices were higher in CA and NE stores compared to the other states. Howev
er, the ratio of liquid and frozen product prices to all large shell egg pr
ices was among the lowest for CA and NC stores. These data indicate that pr
oduct Selection, packaging, and consumer prices for shell eggs and egg prod
ucts varied considerably across five separate regions of the country.
