Risk Edit

Game meat from carnivorous animals may be infected with parasites.
In-game description

On Stalker and Interloper difficulties, there is a risk of contracting intestinal parasites by consuming any quantity of meat from carnivorous animals such as wolves and bears. Cooked meat is not safe from this affliction. Raw meat increases the risk by 75%. The first piece of cooked meat consumed will set the chance to 1%, the second will increase it by 4% and the next pieces of meat will increase it by 5%. Every time meat is consumed the risk is increased, regardless of the weight of meat eaten; therefore, it is more reasonable to consume only full stacks of meat (1 kg/2.20 lbs) to minimize the parasite risk gain. First consumption of the meat, regardless of weight, will increase the risk by 1%.

Unlike hypothermia risk, intestinal parasites don't just happen by reaching 100%. After approximately a day from consuming your first meat, the player experiences a risk check, where the percentage is the chance of getting intestinal parasites, meaning that similarly to infections, it is possible but unlikely to get intestinal parasites with a 1% chance. If you consume so much meat that the risk reaches 100%, you will get parasites immediately.

Eating food items or meat other than bear or wolf meat while under risk of 1-10% is a good way to mitigate the risk of intestinal parasites, as while they have no positive effect on parasite risk, they have no negative effect either.

Affliction Edit

You ate infected meat and now have Intestinal Parasites. Recovery requires multiple daily treatments! You will continue to weaken until treatment has run its full course. [maximum 1 dose/day.]
In-game description

Characters infected with intestinal parasites will lose 2% of their maximum condition a day until they are treated (indicated by a red [ -#% ] next to the player's condition). On top of this, their max Fatigue will reduce by approximately 4% a day (indicated by red on the far right of the Fatigue bar). While this does not seem severe, the hefty length of treatment required to slow the impending death can make this condition a serious force to be reckoned with, and even if the player is as quick as possible with treatments they will suffer a 20% reduction in max condition or even 40% on Interloper, this alone being a serious detriment, increasing the risk of wolf attacks and other injuries. Technically, the intestinal parasites will kill the player in approximately 50 days, but the many complications resulting from this affliction will most certainly finish them before these 50 days are up. It is not recommended to start treatment more than 4-6 days after the infection begins, lest the player risk not being able to keep up with the onslaught of negative effects that rapidly stack up.

Parasites can be treated by consuming 2 doses of antibiotics or a single dose of reishi tea once per day for 10 cumulative days in Stalker mode or 20 cumulative days in Interloper mode, making it the most demanding affliction treatment in the game. Parasites is an affliction in Stalker and Interloper and cannot be contracted in Pilgrim and Voyageur. [1]

It is important to note that eating meat from carnivorous animals while being already infected with parasites has no further negative effect; in long term survival situations, assuming the player has stockpiled enough meat from carnivores, it may even be beneficial to keep the parasites for upwards of a month to reduce the number of total antibiotics and teas consumed in the long run. However, this does not come without risks, and is certainly not the safest strategy for long term survival despite its potential benefits.
