Answer to Question 1

 Physical hazards, such as fasteners, pieces of glass, wood splinters, and others
 Chemical hazards that can contaminate produce during handling or storage, such
as pesticides, fungicides, herbicides, rodentacides, machine lubricants from
equipment, heavy metals, industrial toxins, compounds used to sanitize equipment,
and others
 Human pathogens, such as soil-associate pathogenic bacteria (Clostridium
botulinum, Listeria monocytogenes), feces-associated pathogenic bacteria (Salmonella
spp. and others), pathogenic parasites (Cryptosporidium, Cyclospora) and pathogenic
viruses (Hepatitis, Enterovirus)

Answer to Question 2

 Better and more economical methods for controlling and monitoring temperature
and relative humidity
 Reduced losses due to chilling injury by avoiding temperatures that cause it
 Expanded film wrapping and other treatments to replace waxing to reduce water
loss
 Increased mechanization in all aspects of the harvesting and storage operation
 Development of improved controlled atmosphere (CA) and modified atmosphere
(MA) technology
 Genetically engineered crops to enhance their storage life
