DANGER DOUBLE WRAP DRIVE BELT!

A 19 year old girl slipped while sweeping
the floor beneath the double wrap drive belt;
shown in the illustration. She extended her
right hand for support and ended up with the
right arm severed at the shoulder joint.

This accident occurred in an area that
people normally don't frequent. You might
say that people could not get back there--
but someone did.

If you have an unguarded double wrap
drive belt accessible or not, GUARD IT!
Guard it today. After all, what is an arm
worth?

While you are thinking of accident pre-
vention, look around for other hazards and
correct them. Get some help (often free)
from someone experienced in spotting accidents
waiting to happen. Your local Florida Depart-
ment of Commerce representative welcomes
invitations for courtesy inspections. Also,
your insurance underwriter can frequently be
invaluable. After all, what is an arm worth?

GREEN PEEL COLOR CAN BE CAUSED BY GREASY SPOT FUNGUS AND REGREENING

Control of greasy spot fungus is essential to reduce peel blemishes on fresh
citrus fruit. This fungus also can cause fruit peel to retain green color. Cells
adjacent to the specks,characteristic of greasy spot fungus,retain green color
longer than normal and such areas often fail to respond to ethylene degreening.
This problem is common on grapefruit and 'Temples'. Control sprays should be
applied in June or July. The 1974 Florida Citrus Spray and Dust Schedule (Page 8)
has control recommendations (see Available Publications).

Green peel color caused by greasy spot should not be confused with 'regreening'.
Grapefruit and 'Valencias' remaining on the trees during optimum growing weather in
May and June may develop green color overlaying the characteristic color of the
variety. Regreening starts at the stem-end and the peel in this area becomes both
green and coarse. This green color cannot be removed by degreening with ethylene.

'VALENCIA' PEEL INJURY


There have been reports of stem-end rind breakdown (SERB) on 'Valencia' oranges.
This disorder is characterized by peel injury on the stem end of the fruit with a
narrow ring of unaffected cells next to the button. This type of peel injury can be
greatly reduced by proper handling between harvesting and waxing. Fast handling and
high humidities during this critical time are the key to control. We have been
encouraged to note some packers are holding fruit overnight and over weekends in
degreening rooms with high humidity and air circulation (no ethylene) until it could
be packed. Request Circular 286 from the Available Publications for more details.

REMODELING? PLAN AHEAD


We anticipate another summer of major remodeling in Florida citrus packinghouses.
Various Florida citrus packing organizations have held conferences with us (a free
service if you pay your taxes!) to discuss plans for such changes. Anyone interested
in such a conference just call either of us (813--956-1151). The ground rules are
simple. You bring anyone you want to, and we will call in our staff as their special
skills are needed. Sometimes an initial conference has been followed by several others
involving suppliers, consultant engineers, etc.

In this way we can provide a clearinghouse for available information and experience
completely free of the pressure of having something to sell.

Warning! Late deliveries, back orders and substituted items have become the rule
for many equipment items. Your suppliers and machinery company representatives are beinj
hampered by increasing time lags. Give them a chance to help you make your major change!
before September by making decisions now and placing your orders as soon as possible.
Otherwise, you will be ready to run by September, but no one would dare to promise which
year.

BILINGUAL LABELING AND METRIFICATION

"Canada May Require Bilingual Labeling. If you export to Canada, note these pro-
posed farreaching changes in Canada's Labeling and Packaging Act of 1971.

The changes, which would affect all prepackaged foods and other consumer goods,
would make mandatory bilingual labels in French and English denoting either the common
or generic name of the product or a description of its function. All labels would be
required to show the net quality in both metric and Canadian units of liquid measure
(Imperial gallons, quarts, etc.).

For imported goods, the only exception to the latter regulation would be for goods
labelled in the country of origin showing metric measurement only. Some 46,000 imported
items would fall under the new regulations."
Food Engineering, January 1974

~T Sorry Lhout tNat!


In Packinghouse Newsletter No. 61, March 5, 1974 I presented a graph showing the
movement of fresh fruit over the last twelve seasons. Unfortunately, the vertical
scale is labeled "Millions of cartons shipped fresh", but the values given are for boxes
not cartons. Readers who file these newsletters are asked to change the figures on the
vertical scale from "0, 10, 20, 30" to "0, 20, 40, 60."
