Andy bought a loaf of bread from a bakery, but when reaches home, he
discovers small dark green specks of mould on it. He goes back to the bakery to
get a refund, but owner refuses, insisting the bread was freshly made.
Andy is now wondering what has caused the mould to grow, and what he can do about the situation.

Types of mould
|
Description
|
Cladosporium
 |
Cladosporium - is a very common mould
species. It is usually found in conjuction with Aspergillus or Penecillium
species. It is also a very common outdoor mould. Cladosporium appears gray to black or very
dark green and can have a powdery appearance.
|
Aspergillus
 |
Aspergillus - is a very
common mould species. It thrives in conditions where there is a variation in
moisture. Conditions in building such as infrequent water intrusion, followed
by periods of dryness, such as basements leaking in the spring
time.
|
Eppicoccum
 |
Eppicoccum - grows well on
cellulose surfaces and is often found growing on a variety of building
materials including but not limited to paper, textiles, and insects.Some
people may experience hay fever and or asthma when exposed to this mould.
|
Stachybotyrys
 |
Stachybotyrys - is what
most people commonly refer to as "black mould". It is actually a
greenish-black fungus that colonizes particularly well in high-cellulose
material and cellulose-containing
building material that becomes
chronically moist or water damage due to excessive humidity, water leaks,
condensation or flooding.
|
Penicillium
 |
Penicillium - encompasses more
than 150 species. Penicillium is a cryophilic fungi, which means it likes the
cold, growing best at 34 degrees .
It is xerophilic, which means it can obtain moisture from the air if humidity
is at 60% or higher. When it is more than two weeks old, it is bluish in
colour.
|
Ulocladium
 |
Ulocladium - has
moderately rapid growth rate. The colonies, which reach maturity within 5
days, are brown to olivaceous-black or greyish and suede-like to floccose
(wooly to cottony). Ulocladium spores are
mainly dispersed by air. Ulocladium has a high water requirement, and indoors
is found where there is high moisture.
|
Mucor
 |
Mucor - colonies are
typically white to beige or grey and fast-growing. . Older colonies become grey to
brown in colour due to the development of spores. Mucor species are very aggressive, and they
will quickly overrun an environment and dominate other fungi. The mold grows
and spreads quickly, making it difficult for slower-growing fungi to compete.
|
Chaetomium
 |
Chaetomium - is one of
those moulds that require chronic moisture conditions for it to grow. It’s
presence is therefore an indication of existing or previous serious moisture
problem. Chaetomium globosum is known to produce 2 toxins in moisture
damaged buildings, chaetoglobosins A and C. Mould commonly found in soil, air, and
decaying plant material.

I think to get a very clear clarification on consumer right regarding this issue, the action plan should not just discuss in group but you should ask the customer society in which they are more expert on this :)
very detail information about the moulds that may cause the bread to become rotten, very amazed!. I also agreed with hanim's opinion. Perhaps customer's right should be include too, however, in our country, if such things happened, someone seems to just keep quiet and never complain anything.
