Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: the patient is a 61-year-old gentleman seen by dr. previously for a lower anterior resection of rectus sigmoid carcinoma on . follow-up ct of the chest and abdomen on , showed a large area of heterogenous perfusion measuring 8.6 x 7.7 cm. upon subsequently admission to the hospital on for chest, abdominal and back pain, he received another ct scan of the abdomen that displayed a poorly defined area of heterogenous enhancement located within the right lobe of the liver that increased in size compared to the prior exam. the lesion was deemed to be a metastatic spread of his previous colon cancer, and he was planned for elective surgery. he was seen by cardiology and anesthesia prior to surgery and was cleared. he was admitted on , for exploratory laparotomy with possible excision of the right hepatic lobe. the lesion was deemed unresectable at the time of surgery, and the patient was closed. the patient tolerated the procedure well. postoperatively he complained of some abdominal pain but did quite well otherwise. he was transferred to the and seen by the acute pain service team. he was continued on epidural with meperidine. on , the epidural was discontinued. during his stay in the hospital, a right internal jugular triple-lumen catheter was placed with no complications. he tolerated the procedure well, and his chest x-ray showed no evidence of pneumothorax and showed good placement of the catheter tip. on , he was transferred to the intensive care unit as he was found unresponsive, cyanotic and hypoxic. he was hemodynamically stable but intubated and ventilated. chest x-ray at the time showed right upper lobe and right middle lobe infiltrates but no evidence of pneumothorax. ct of the chest ruled out the presence of a pulmonary emboli. head ct was normal. the patient's troponins were negative as well. the patient was diagnosed with aspiration pneumonitis, and he was diuresed gently with lasix. he was subsequently extubated on , and tolerated this procedure well and remained hemodynamically stable. the patient was subsequently transferred to the . on exam the patient was well. his temperature is 98.9??????, heart rate 60, blood pressure 140/78, respirations 20, oxygen saturation 94% on room air. he was alert and oriented times three. he had clear lung fields. there were normal heart sounds. his abdomen is soft and nontender and slightly obese. he has good peripheral pulses. he has been eating a regular diet and ambulating. he is currently stable for discharge. discharge medications: heparin 5000 u b.i.d. subcue, aspirin 81 mg p.o. od, zosyn 4.5 mg q.i.d., axopt, travatan, morphine sulfate, cepacol, metoprolol, isosorbide, mononitrate, celexa, zofran, percocet, lasix. this discharge summary will be amended. , m.d.,ph.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube arterial catheterization other laparotomy insertion of catheter into spinal canal for infusion of therapeutic or palliative substances systemic to pulmonary artery shunt diagnoses: malignant neoplasm of liver, secondary other postoperative infection cellulitis and abscess of trunk congestive heart failure, unspecified other specified forms of chronic ischemic heart disease pneumonitis due to inhalation of food or vomitus respiratory arrest personal history of malignant neoplasm of rectum, rectosigmoid junction, and anus 

Answer: The patient is high likely exposed to
