4. Mechanism of Intoxification
Campylobacter jejuni attached to
mucosal cell receptor in our body cell
and produce toxin.
ATP cAMP
The toxin influence the conversion of ATP to
body energy, and change it to become Cyclic
AMP. (Influence by activating enzyme
responsible for the conversion)
cAMP then blocks the uptake of Na+ ion to
mucosal cells in intestinal lining. This will make
the ion accumulate and cause osmotic
inbalance. This will cause watery diarrhea.

5. Mechanism of Virus Transmission
6. Mechanism of Parasitic infections
All information from comic and the comic notes section were obtained from:
Understanding Food Science and Technology International Edition
by Peter S. Murano
Food Contaminated
with Virus
Food Consumed
Virus is not digested and
incubate inside body
Ilness occur
Unsporulated cyst
Enviromental condition make cyst sporulated into food
chain
Sporulated cyst in food is consumed
Inside body: Cyst become excystation
(release parasite)
Parasite form
zygote
Zygote become unsporulated
cyst and release through
excretion in stool.

Short Communication Essay
A Foodborne Disease story: present and future
As a quick review, the foodborne disease outbreak in America is abundance. 48
million illness were estimated to occurred in America ANNUALLY (Control et al.,
2011). A comparison of surveillance on foodborne disease outbreak in America
between 1998-2002 and 2008, shows a drastic difference in terms of what is
causing human sick. In 1998-2002, Salmonella serotype Enteritis accounted for the
largest number of outbreaks and outbreak-related cases; the runner-up, Norovirus,
is a viral transmission virus that cause infectious through contaminated food or
water and even surfaces (Lynch et al., 2006). However, in 2008, Norovirus become
the no. 1 in causing the most foodborne disease outbreaks (Control et al., 2011).
As you know from the comic, virus transmission occur most probably due to
incompetent food handling process. The society must learn that they have to
choose good food from good source. However, from the data, the people of
America do not follow the advice. This does not to say that Americans are ignorant,
but the Centre for Disease Control is the only one publishing the data free and
consistently in the world. So, the Americans become the model in this context. We
can learn from these data to extrapolate to our country, although not accurately
but suffice for estimation of each of the countries behavior (America is still a
huge country you know, they have population almost of any kind)
As a fellow person from Malaysia, I advised anyone to be cautious of the
food you buy from hawkers, or restaurants. In Malaysia, there were a lot food
hazard issues (Izham Nayan, 2012), from sacrilege religion (Islamic Halal) to
unhygienic conditions (Failed food quality control policies). However, these were
due to people’s greed. All of these can be changed (although it will be a daunting
challenge). But what about to happen next is beyond our grasp.
As we know, Global Warming is real, and it is becoming reality. Although
there are attempts of climate denials in media (Emily Atkin, 2014; Hoggan et al.,
2009; Owen et al., 2010), Courts ("Native Village of Kivalina v. ExxonMobil Corp,"
Published in Academicomic.wordpress.com 12
2009) in which Some succeed, some didn’t. There are even literature studies on
why the population does not believe global warming (Boykoff et al., 2004; Maibach
et al., 2014).
The effect of global warming to the foodborne disease is substantial.
According to a research report (Hall et al., 2002), unpredictable weather and its
subsequent disaster could lead to disarray of food logistics and hygiene. Change in
temperature could render the equipment for food preservation useless due to poor
temperature control in changing climate. Temperature rising could also increase
the growth of cyanobacteria (Blue-green algae) in water supplies and recreational
water bodies. This will lead to mass bacterial intoxication. Foodborne Disease will
be ubiquity.
However, there is still hope (and time). We, as a human, must be vigilant. It is our
nature to learn and learn we must. We must learn on how to prevent the foodborne
disease pathogens spread as well as practice it. Then, we must devise a plan or
strategy (even on individual basis) on acquiring good and hygienic basic food supply.
These include learning and practicing agriculture or simple food preservation
technique. Global warming will come (unless some miracle happen), but until then, we
must equipped ourselves with proper knowledge and the capability to overcome it.
