Proper
sanitation is probably the most important aspect of any pest
prevention or control programme. Sanitation robs pests such
as flies, cockroaches, rodents and ants of the food they need
to survive. Keep all areas such as counter tops, sinks, floors,
cupboards and machinery free of food scraps and spilled liquids.
Keep food in secure containers and store durable commodities
such as rice in the refrigerator if being kept for long periods.
Ensure that garbage cans are properly covered and emptied
frequently. Regular inspection and proofing i.e. blocking
areas for pest entry, must be included in any pest control
programme. |

A
fumigant is a toxic chemical used in the gaseous state in
to kill or control a target organism. Fumigants must usually
be used in a sealed area at the proper concentrations and
time periods in order to be effective. Fumigants must only
be used by trained persons. The only two fumigants approved
for use in Jamaica are methyl bromide and phosphine. |

Mycotoxins
are toxic chemicals produced by certain species of fungi.
If contaminated food is consumed, these toxins can lead to
illnesses such as cancers, birth defects and inflammation
of the digestive tract in humans. In livestock, mycotoxins
can cause lowering of meat or milk production, increased susceptibility
to infections and difficulties in reproduction. |

Insects
belong to the phylum Arthropoda, class Insecta. About one
million different species of insects have been described and
entomologists believe that there may be millions that a yet
to be discovered. Most insects are not harmful to man. Some,
however, such as certain species of cockroaches, flies
and ants infest homes, food and food areas and can also be
vectors of disease. Some beetle species infest stored food
and agricultural crops. Note that spiders and mites are not
insects. |

A
stored product pest is an insect (or a mite) that lives, reproduces
and feeds on and in durable stored commodities such as rice,
corn, flour, spices, tobacco and lumber. e.g. the rice weevil
(Sitophilus oryzae) the rust-red flour beetle
(Tribolium castaneum)
and tropical warehouse moths (Ephestia spp.). Stored product
pests can cause great loss in food quality and quantity. The
larval stage of the insect usually does the most damage |

Squirrels
and beavers are rodents but are not found in Jamaica while
mongooses and bats are not rodents. Coneys are protected species
and must not be harmed. A rodent is a mammal which has large,
strong incisors, no canine teeth and a space (diastema) between
the incisors and molar teeth. Rodents belong to the order
Rodentia which means "to gnaw". |

Cockroaches,
rats, mice and flies are capable of spreading disease because
of their filthy habits. This is one important reason why infestation
must be controlled |

Minimally
processed/fresh cut/lightly processed fruits and vegetables
are prepared by a single or any number of the appropriate
unit operations such as peeling, slicing, shredding, juicing,
coring, chopping that do not affect the "fresh-like quality"
of the fruit or vegetable (Burns, 1995). It differs from traditional
processing as the tissues remain viable or fresh during handling
and the tissue's behaviour is typical of that observed in
plant tissues that have been wounded or exposed to stress
conditions (Brecht, 1995) |

Stacks
of food in containers must be stored at least two feet away
from walls, four feet away from ceilings and (stacks of food
in containers which are not waterproof) four inches off the
floor. |
