Onions (Allium cepa), a vegetable plant is consumed globally for its culinary and medicinal importance. Despite the various health benefits ascribed to onions, several rumours have been spread, especially on the online media as regards its ability to act as a sponge absorbing microorganisms from the atmosphere, once cut open and left exposed in the atmosphere.
 This research work involved the exposure of the half portion of an onion at different sites, while culturing the other half immediately without exposure, to serve as a control. Thirty healthy and fresh onion samples were exposed, and the sites of exposure include: living rooms, public conveniences, kitchens, fridge, freezer, and bole joints (roasted plantain eatery).
 After inoculation and identification of the cultured microorganisms, Pseudomonas sp., Bacillus cereus, Escherichia coli, Staphylococcus sp., Klebsiella sp., Enterobacter sp., yeast and Aspergillus sp., were isolated with Klebsiella sp., Pseudomonas sp. and Staphylococcus sp. having the highest number of occurrence of 40% having been isolated from twelve test samples each. B. cereus had a percentage occurrence of 30%, having been isolated from nine test samples. E. coli had a 10% occurrence having been isolated from three test samples, while Enterobacter sp. had the lowest rate of occurrence having been isolated in just one test sample. For the fungi isolates, Aspergillus sp. had a percentage occurrence of 76.6% having been isolated in twenty three test samples, while yeast had a percentage occurrence of 66.6%, having been isolated in twenty test samples.
 The isolated organisms were all pathogenic organisms, and some such as Staphylococcus sp. and Bacillus sp. have been implicated in causing food poisoning. Some other organisms isolated have also been implicated in the spoilage of onions. It is therefore recommended that users of onions should reduce to the barest minimum the tendency to consume raw cut onion sample.

given to parrots. Other foods are not necessarily toxic, but should only be given in a limited capacity. Two examples of this are garlic and onion. Another
A companion parrot is a parrot kept as a pet that interacts abundantly with its human keeper. Parrots are among the most popular companion birds worldwide, but most species are not domesticated and retain the complex behavioural and environmental needs of wild parrots, including flocking, social interaction, varied foraging and regular flight. Reviews of parrot welfare report that many companion p
Different species (sometimes even different individuals within species) can vary greatly in temperament, noise, and talking ability. For example, Pionus parrots generally have a reserved stance, while at the other end, large cockatoos need at least several hours of attention daily. The upbringing and genetic inclination of an individual bird plays a major role in determining its disposition, regardless of species.
Many of the larger parrots are unsuitable in an apartment setting due to noise level. Although all parrots will make some noise, species that are generally less noisy include parrotlets, budgies, cockatiels, Pyrrhura conures, Pionus, caiques, greys, and usually Poicephalus. Many of the other species of conures can be loud birds. Cockatoos, and many macaws and amazon parrots can be very loud, though normally only at certain times of the day and some birds will learn to scream for attention.
Many people are initially attracted to parrots for their ability to talk, sing, and mimic noises they are exposed to. Some parrot species such as greys, eclectus, quaker parrots, male and some female budgies, and some species of amazon parrots, macaws, and Psittacula are frequently good talkers and mimickers, although there is no guarantee that any individual parrot will talk. Many parrots learn to use words in context; for example, calling family members by name, or requesting certain food items by name. Other species are poor talkers, but popular for their affectionate or playful personalities.
Parrots need a cage large enough to exercise in, stretch their wings, and climb if it will not be out for a good part of the day. Without exercise, parrots tend to become obese and unhealthy.
Toys (enrichment) are necessary for pet parrots. Different birds may have very different toy preferences. Toys should be sized appropriately for the bird's size and destructiveness; for example, a small plastic budgie toy could be dangerous for a large parrot that could break off and ingest a piece. Some birds may prefer wooden toys to chew up; some may prefer bells or other toys that make noise; some may prefer toys with leather strips they can untie; some may prefer a bowl of small…
