1
00:00:00,110 --> 00:00:11,369
The anisakis eats a nematode worm that expands its life cycle in the digestive tract of fish

2
00:00:11,369 --> 00:00:13,009
and marine mammals.

3
00:00:13,009 --> 00:00:18,129
When the human being injects infected fish, this worm can cause digestive and allergic

4
00:00:18,129 --> 00:00:19,129
reactions.

5
00:00:19,129 --> 00:00:26,699
They are thin and flat worms, their white is almost transparent color, they measure

6
00:00:26,699 --> 00:00:35,020
between 4 and 6 cm when stretched.

7
00:00:35,020 --> 00:00:43,820
This is the disease caused by the larvae of the small round worms of the Anisakidae family.

8
00:00:43,820 --> 00:00:49,899
The most characteristic member of this family and the one that causes the greatest number

9
00:00:49,899 --> 00:00:57,219
of infections is the Anisakis simplex.

10
00:00:57,219 --> 00:01:04,680
The Anisakis was discovered in 1845 by Félix de Jardin, which was a friend doctor, naturalist,

11
00:01:04,680 --> 00:01:12,760
geologists and zoologists who identify the adult worms.

12
00:01:12,760 --> 00:01:18,840
We can find them in those fishes that do not require heat for their preparation and are

13
00:01:18,840 --> 00:01:27,099
consumed raw, smoked, marinated in vinegar and in saltine such as the anchovy, salmon

14
00:01:27,099 --> 00:01:28,099
and sardine.

15
00:01:28,099 --> 00:01:36,159
They are also common in cephalopods, oedipides, cuttlefish and squid crustaceans like prawns

16
00:01:36,159 --> 00:01:45,079
and lobsters. Most common fishes such as hake and bonito.

17
00:01:45,079 --> 00:01:50,680
In most cases we can find them in the intestine, but sometimes anisakis are located in the

18
00:01:50,680 --> 00:01:57,299
abdominal cavity or in the thoracic cavity. It can also affect different organs such as

19
00:01:57,299 --> 00:02:02,219
the liver, the pancreas and the ovary.

20
00:02:02,219 --> 00:02:07,859
Do not buy fish in market that is into boxes containing water or ice.

21
00:02:07,859 --> 00:02:14,139
Check that the food is in good condition, with a nice appearance and appropriate smell

22
00:02:14,139 --> 00:02:15,479
and color.

23
00:02:15,479 --> 00:02:23,180
Ensure that the fish you have brought indicate that it has been previously frozen.

24
00:02:23,180 --> 00:02:28,740
The main anisakis symptoms can be digestive or allergic and they always appear quickly,

25
00:02:28,740 --> 00:02:31,960
12 hours after the ingestion.

26
00:02:31,960 --> 00:02:38,340
It usually starts with a strong pain in the abdomen, accompanied by nausea and vomiting.

27
00:02:38,340 --> 00:02:45,020
The symptoms usually persist for only a few days, a week as much, but in some cases it

28
00:02:45,020 --> 00:02:49,750
may last longer.

29
00:02:49,750 --> 00:02:55,610
Sometimes it is possible to detect and extract the parasite, but in the case that you have

30
00:02:55,610 --> 00:03:00,289
stomach ache or something similar, gastric protectors are used.

31
00:03:00,289 --> 00:03:06,289
If you have allergy symptoms, you can use corticosteroids and antihistamines.

32
00:03:06,289 --> 00:03:11,289
It can also be struck by surgery or digestive endoscopy.

33
00:03:11,289 --> 00:03:23,669
The bad practices of deep sea fishing of the fish, with the uncontrolled elimination of the viscera, is what is producing the contamination of the seas.

34
00:03:23,669 --> 00:03:30,669
The methods to eliminate this parasite are simple, because the parasite lives mainly in the viscera of the fish.

35
00:03:30,669 --> 00:03:33,770
You will try to esquire fish without viscera.

36
00:03:34,330 --> 00:03:39,909
In case of esquiring whole fish, it is advisable to eviscerate as soon as possible.

37
00:03:40,469 --> 00:03:48,710
So instead of throwing the viscera to the sea, they have to burn it because if not, the viscera in the sea contaminates other fishes.

38
00:03:49,710 --> 00:03:52,069
At first, marine mammals scrape the eggs.

39
00:03:52,469 --> 00:03:57,090
After that, two larvae stages are developed inside the same egg.

40
00:03:57,590 --> 00:04:01,509
Later, the eggs hatch and larvae swim freely in the sea.

41
00:04:02,250 --> 00:04:04,229
Next, a krill eats the larvae.

42
00:04:04,710 --> 00:04:08,430
And then, fish eats the krill that has just eaten the larvae.

43
00:04:08,710 --> 00:04:10,969
And the fish is eaten by another fish.

44
00:04:11,610 --> 00:04:14,349
Finally, marine mammals eat infected fish.

45
00:04:15,009 --> 00:04:19,009
Larvae mario mates and lay eggs in the intestine.

46
00:04:19,009 --> 00:04:25,990
The humans eat infected rod or undercooked fish and become accidental hods.

47
00:04:27,089 --> 00:04:29,050
Thank you.
