When evaluating a hazard, the
hazard evaluation determines if the
hazard will cause potential harm
to the person consuming the egg.
Starting at the beginning of the
flowchart, we will assume the egg
packing operations obtain eggs
from in-line and off-line production facilities and nest run truckload
purchases.
One example prerequisite
program of a biological hazard
noted in the hazard analysis of
the presented plan is at receiving
off-line eggs. The temperature
of incoming eggs will vary from
season to season and from operation to operation. Source of packing

materials will vary, with plastic
flats, reused pulp paper flats or new
flats, transport racks or pallets and
how everything is cleaned.
General feed hazards include
receiving and storage of the
grain and other ingredients. The
biological hazard in feeds is
Salmonella; currently, that is the only
one under regulation.
The two types of chemical hazards
are mycotoxin levels and drug medication carryover. Mycotoxin levels
in the feed may affect the safety of
the product for animal and human
consumption. Drug medication carryover may occur if there is commingling in the feed bins with previously

A critical limit is a maximum or
minimum value at which a biological, chemical or physical hazard
must be controlled to prevent, eliminate or reduce the identified food
safety hazard.
For each critical control point
(CCP) identified, operational limits or
boundaries must be set. If the process
remains within these limits, hazards
are being controlled effectively.

Monitoring
Monitoring is a planned sequence
of observations or measurements to
establish whether a CCP is under
control. Monitoring instances must
be properly documented to produce
an accurate record for future verification and of monitoring procedures
based on an identified lot of product.
All CCPs must be monitored to
determine compliance with established critical limits. Companies
want to be proactive in preventing
any biological contaminants from
reaching the consumer. However,
egg operations who want to rigorously look for risk are faced with the
dilemma of what they must report if
they find something that has not yet
caused a problem.
Based on the regulations and
the reportable biological controls,
there is no incentive for companies
to be proactive in their microbiological monitoring. This reporting
