Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    STUDIES ON ADULTERATION OF MILK AND ITS PUBLIC HEALTH IMPORTANCE IN HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2018) Palsra, Tanu; Khurana, S. K.
    The present study was conducted to assess the milk quality with reference to adulteration and its importance on consumers’ health in different areas of Himachal Pradesh. Total 200 raw milk samples were collected directly from consumers. Milk analysis was done firstly to assess the physico-chemical quality attributes and further qualitative analyses of adulterants. The specific gravity of milk samples ranges from 1.010-1.032 with an average value 1.022±0.005. The fat percentage ranges from 1.0-9.2 with an average value 3.5±0.10, SNF ranges from 3.6-12.8 with an average value 7.01±0.10 and Total Solid ranges from 4.6-19.2 with an average value 10.54±0.17. Total 74% milk samples in case of specific gravity, 69.5% samples for fat percentage, 82.5% samples for SNF, and 73.5% milk samples for TS were less than the minimum prescribed standards of FSSAI for specific gravity, fat, SNF, and TS for cow milk in Himachal Pradesh. Further zone-wise determination of physico-chemical parameter of milk samples revealed that there was no significant difference (p>0.05) in specific gravity and %SNF content between Zone I and Zone II whereas, there was significant difference (p<0.05) of Zone III with Zone I and Zone II. No significant difference was observed between Zone I, Zone II, and Zone III in case of fat% and TS. All these samples were analysed for presence of adulterants by using a standard milk adulteration kit. Tests included were alizarin test, urea test, starch test, salt test, skim milk powder test, glucose test, formalin test, sugar test (sucrose), neutralizers test, detergent test, hydrogen peroxide test, maltose test, ammonium sulphate test, boric acid test, nitrate/ pond water test. Assessment of adulteration depicted that water was the most common adulterant (74%) found in the milk samples followed by salt (18%), alizarin (13.5%), skim milk powder (9.5%), detergent (3%), sucrose (1.5%), glucose (1%), formalin (1%), and neutralizers (1%). Other tests performed were negative in all milk samples. None of the individual sample was found positive for all the synthetic ingredients (urea, detergent or soap, sodium hydroxide, vegetable oil, and salt) required for production of synthetic milk. From survey study it could be concluded that majority of the respondents had low awareness towards disease transmission through milk, government regulations against milk adulteration and proper reporting system. Majority of respondents preferred the method of assessment of adulteration was through visual appearance, taste, touch and they perceived that adulterated milk had no harmful effect on their health

    STUDY ON INCIDENCE OF BACILLUS SPP. IN READY-TO- EAT FOODS, BEVERAGES AND WATER FROM DIFFERENT TOURIST PLACES OF HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2018) Rana, Neha; Panda, A.K.
    The present study was designed with the aim to determine the incidence of Bacillus species in ready-to-eat (RTE) foods, beverages and water from different tourist places of Himachal Pradesh. Bacillus were also analyzed for the presence of toxin genes and antimicrobial susceptibility. A total of 220 samples; RTE milk products (n=80), RTE meat products (n=40), beverages (n=40) and water (n=60) were tested. In addition, 50 stool samples from hospitalized patients were also screened. Bacillus isolates were characterized by cultural and biochemical methods and reconfirmed by amplifying 16S rRNA (1500 bp) through polymerase chain reaction (PCR). Bacillus isolates were characterized for the presence of enterotoxins (hbl encoding hemolytic, nhe encoding non-hemolytic and cytK encoding cytotoxic) and emetic toxin (ces) by multiplex PCR. A total of 11.4 per cent (n=25/220) samples tested were contaminated with Bacillus species. These isolates were identified as B. cereus (76%, n=19/25), B. alvei (12%, n=3/25), B. polymyxa (8%, n=2/25) and B. firmus (4%, n=1/25). RTE milk products were found to have the highest incidence of Bacillus (17.5%, n=14/80) followed by water (8.3%, n=5/60), RTE meat products (7.5%, n=3/40) and beverages (7.5%, n=3/40). None of the stool samples were found positive for Bacillus spp. B. cereus recovery was highest from cheese (25%, n=4/16) followed by khoa (14 %, n=3/21) and paneer (8.6 %, n= 2/23) based items. nhe complex was detected as the predominant (76%) enterotoxin gene, followed by cyt K (40%) and hbl gene complex (28%). ces was not present in any of the tested isolates. All the isolates were resistant to cefixime and penicillin. High level of susceptibility was observed for antimicrobial classes; aminoglycosides, quinolones and phenicols. MDR was found in 28 per cent (n=7/25) isolates of Bacillus spp. Highest number of MDR isolates were recovered from RTE milk products (12%) followed by water (8%), RTE meat products (4%) and beverages (4%).

    STUDIES ON INCIDENCE OF AEROMONAS SPP. IN READY-TO-EAT FOODS, BEVERAGES AND WATER FROM DIFFERENT TOURIST PLACES OF HIMACHAL PRADESH
    (CSKHPKV, Palampur, 2018) Neena Kumari; Panda, A.K.
    The present study was designed with the aim to determine the incidence of Aeromonas species in ready-to-eat foods, beverages and water from different tourist places of Himachal Pradesh. A total of 220 samples; RTE milk products (n=80), RTE meat/fish products (n=40), beverages (n=40) and water (n=60) were collected from 12 different tourist places. In addition, 50 stool samples from hospitalized patients were also screened. Aeromonas isolates were characterized by cultural and biochemical methods and reconfirmed by amplifying 16S rRNA (953 bp) through polymerase chain reaction (PCR). Enterotoxin genes alt (encoding heat-labile cytotonic enterotoxin), ast (encoding heat-stable cytotonic enterotoxin) and act/hlyA/aer (encoding cytotoxic/β-haemolysin/aerolysin) complex present in characterized Aeromonas isolates were detected by PCR. A total of 20 Aeromonas spp. isolates were recovered from tested samples; 16 from RTE foods, beverages, water and 4 from human stool samples. RTE milk products had highest level of contamination (n=12/80, 15%) followed by beverages (n=3/40, 7.5%) and water (n=1/60, 1.67%). These isolates were identified as A. hydrophila (n=7/20, 35%), A. sobria (n=6/20, 30%), A. schubertii (n=4/20, 20%) and A. veronii (n=3/20, 15%). All Aeromonas isolates carried alt and 25 per cent were positive for act/hlyA/aer complex. None of the isolates was carrying ast. High level of susceptibility was observed for antibiotic classes; nitrofurans, phenicols and tetracyclines followed by quinolones and aminoglycosides. However, all the isolates were resistant to ampicillin. Nine (45%) isolates were multidrug resistant. Highest number of MDR isolates were recovered from RTE milk products (25%) followed by stool samples (15%) and beverages (5%).
