“…Broken needles and needle fragments in pork carcasses also present a risk factor for physical hazard in the pig industry. 9 These risks could be eliminated by needle-free injection devices (NFID). Furthermore, needles can serve as mechanical vectors for the spread of haematogenous transferable pathogens like porcine reproductive and respiratory syndrome virus (PRRSV) 10 11 and Mycoplasma suis.…”

“…Although needle stick and sharps injuries are a major occupational health hazard in veterinary practice, 8 most vaccines are still administered by injection with needle‐syringe devices. Broken needles and needle fragments in pork carcasses also present a risk factor for physical hazard in the pig industry 9 .

The present study compares the safety and efficacy of a needle-free, intradermal vaccine to an intramuscular one. 420 piglets (21+3 days of age) were randomly assigned to two vaccination groups (intradermal vaccination V1 (n=138), intramuscular vaccination V2 (n=144)) and one unvaccinated control group (CG, n=138). As safety parameters clinical observations, local injection site reactions (ISR) and rectal temperatures were assessed. Average daily weight gain (ADWG) and pneumonic lung lesions (LL) were measured as efficacy parameters. ISRs were minor in V1. After both vaccinations, no adverse impact on appetite was observed and mean rectal temperatures remained within physiological range. ADWG during the fattening period was significantly higher in vaccinated groups (V1: 913.4 g, V2: 924.5 g) compared with CG (875.6 g). No differences in ADWG were observed between V1 and V2. Vaccinated pigs had a significantly reduced mean extent of LL compared with CG. V1 was superior in reducing the extent and prevalence of LL compared with V2. These results reveal that a needle-free intradermal vaccination is safe and efficacious in reducing both the prevalence and extent of lung lesions, as well as in improving performance parameters, in a farrow-to-finish farm with a late onset ofe infection.

“…It is caused by a bacterium that is widely distributed in pig faeces [186] which is not, however, the main source of contamination for humans [185]. Human infections are mainly caused by Campylobacter jejuni [185] while Campylobacter coli is the most common species in pigs [187]. According to one study, there is no significant difference in the prevalence of C. coli carriage between pigs from organic and non-organic farms [188].…”

Pig Farming in Alternative Systems: Strengths and Challenges in Terms of Animal Welfare, Biosecurity, Animal Health and Pork Safety

In pig production, the widespread conventional indoor system with a slatted floor currently dominates. However, this production system is becoming less socially acceptable. In addition to general environmental protection issues, animal welfare, the absence of suffering and distress, and the management of pain also constitute societal concerns. In this context, alternative production systems are gaining ground. Although they are popular with consumers and other citizens, these alternative systems have their critical points. Here, we reviewed the international scientific literature to establish the state of the art of current knowledge regarding welfare, biosecurity, animal health and pork safety in this type of farming system. In general, alternative farms give pigs the opportunity to express a broader range of behaviours than conventional farms. However, the management of feeding, watering, temperature and predators is often more complicated in these outdoor systems. In addition, biosecurity measures seem to be applied less strictly in alternative farms than in conventional farms, especially in free-range systems, where they are more difficult to implement. On the other hand, pigs kept in these farming systems seem to be less affected by respiratory diseases, but parasitism and piglet crushing (in farrowing units) both remain a real challenge. Furthermore, the higher prevalence of many zoonotic pathogens in these farms may represent a risk for human health.
